WPILib安装指南
This guide will walk you through installing the WPILib development environment on your computer. This includes the WPILib tools, Visual Studio Code, and all dependencies needed to develop and deploy code to the roboRIO. WPILib Installation is required for Java and C++ teams. LabVIEW teams can skip to 安装LabVIEW for FRC（仅LabVIEW）. Python teams can do a full install per these instructions to get a Visual Studio Code environment with some python extensions, or do a tools only installation to install dashboards such as Shuffleboard and Elastic. Python teams additionally need to follow the Python Installation Guide.
先行准备
- Supported Operating Systems and Architectures:
Windows 10 & 11, 64 bit only. 32 bit and Arm are not supported
Ubuntu 22.04 & 24.04, 64 bit. Other Linux distributions with glibc >= 2.34 may work, but are unsupported
macOS 13.3 or higher, both Intel and Arm.
警告
The following OSes are no longer supported: macOS 12 or earlier, Ubuntu 18.04 & 20.04, Windows 7, Windows 8.1, and any 32-bit Windows.
备注
Windows 10 support from Microsoft ended in October 2025. We intend to continue supporting Windows 10 through the 2026 season, but may have to drop support in 2027. Teams should start planning their upgrade path to Windows 11, or switch to one of the supported Linux distributions listed.
备注
C++ compilation is memory intensive. A minimum of 32 GB of RAM is recommended for C++ teams.
This tutorial shows Windows 11, but the steps are identical for all operating systems. Notes differentiating operating systems will be shown.
WPILib is designed to install to different folders for different years, so that it is not necessary to uninstall a previous version before installing this year’s WPILib.

Release Notes
This is an update release of WPILib for the 2026 season. This release adds 2026 season-specific field images and AprilTag information as well as a handful of other minor improvements and fixes. This upgrade is recommended for all teams.
Upgrading from earlier 2026 releases is easy: simply download and run the new installer and it will update your current installation. If you already have the 2026 WPILib vscode installed, it will detect it and you can simply click "next" for that installation step. After installation, vscode will prompt you when opening your robot project whether you want to upgrade it to this version. Note that using the installer is required to get the new version of desktop tools such as Elastic and AdvantageScope. This release is compatible with the kickoff release of the RoboRIO image, so there is no need to upgrade the RIO image if you have already done so for 2026.
The documentation for WPILib is located at https://docs.wpilib.org/ (if you have trouble accessing this location, https://frcdocs.wpi.edu/en/stable/ is an alternate location with the same content).
If you're new to FRC, start with Getting Started.
System Requirements: WPILib requires 64-bit Windows 10 or 11 (Arm and 32-bit are not supported), Ubuntu 22.04 or later, or macOS 13.3 or later. C++ teams should note that the latest version of Visual Studio 2022 is required for desktop builds. Mac users will need to have the Xcode Command Line Tools installed before running the installer. This can be done by running xcode-select --install in the Terminal.
If you're returning from a previous season, check out what's new for 2026. You will need a new RoboRIO image for 2026; this is available via the FRC 2026 Game Tools. Follow the WPILib installation guide to install WPILib.
If you're starting from a 2025 robot project, you will need to import your project to create a 2026 project. The import process is important, as it will make a few automated corrections for some breaking changes that happened in 2026. It is also necessary to import vendor libraries again, since last year’s vendor libraries must be updated to be compatible with this year’s projects.
A complete list of known issues with this release can be found here.
WPILib is developed by a small team of volunteers and the FIRST community.

You can also download the latest release of the installer from GitHub.
Once on the GitHub releases page, scroll to the Downloads section.
Then click on the correct binary for your OS and architecture to begin the download.
解压缩安装程序
当您下载WPILib安装程序时，对于Windows，它作为磁盘映像文件.iso分发；对于Linux，它作为.tar.gz分发；对于MacOS，它作为DMG分发。
Windows 10+ users can right click on the downloaded disk image and select Mount to open it. Then launch WPILibInstaller.exe.
备注
Other installed programs may associate with iso files and the mount option may not appear. If that software does not give the option to mount or extract the iso file, then follow the directions below.
You can use 7-zip to extract the disk image by right-clicking, selecting 7-Zip and selecting Extract to…. Windows 11 users may need to select Show more options at the bottom of the context menu.
After opening the .iso file, launch the installer by opening WPILibInstaller.exe.
备注
After launching the installer, Windows may display a window titled “Windows protected your PC”. Click More info, then select Run anyway to run the installer.
备注
Ensure you’ve ejected any previous WPILibInstaller images from the desktop before starting installation
macOS users can double click on the downloaded dmg and then select WPILibInstaller to launch the application.
If a warning is shown about WPILibInstaller being downloaded from the internet, select Open.
Linux用户应解压缩下载的.tar.gz，然后启动WPILibInstaller。 Ubuntu将文件浏览器中的可执行文件视为共享库，因此双击将不会运行它们。在终端中运行以下命令，而不是将“ <version>”替换为要安装的版本。
$ tar -xf WPILib_Linux-<version>.tar.gz
$ cd WPILib_Linux-<version>/
$ ./WPILibInstaller
运行安装程序
打开安装程序后，将显示以下屏幕。继续并按：Start。
This showcases a list of options included with the WPILib installation.
Tools Only installs just the WPILib tools (SmartDashboard, Shuffleboard, RobotBuilder, OutlineViewer, PathWeaver, Glass, SysId, Data Log Tool, roboRIO Team Number Setter, AdvantageScope, Elastic, WPIcal) and JDK.
Everything installs the full development environment (VS Code, extensions, all dependencies, C++ compiler and JDK), WPILib tools, and documentation
您会注意到两个按钮，“为此用户安装”和“为所有用户安装”。为此用户安装仅将其安装在当前用户帐户上，并且不需要管理员特权。然而，为所有用户安装安装工具，所有系统帐户和将需要管理员权限。为所有用户安装不是macOS和Linux的选项。
备注
If you select Install for all Users, Windows will prompt for administrator access through UAC during installation.
选择适合您的选项，然后将显示以下安装界面。
下一个界面涉及下载VS Code。不幸的是，由于许可原因，VS Code无法与安装程序捆绑在一起。
Download for this computer only
这仅下载当前平台的VS Code，这也是最小的下载。
Skip and don’t use VS Code
跳过安装VS Code。对于高级安装或配置很有用。通常不推荐。
Select existing VS Code archive for offline install on this computer
选择此选项将弹出提示，允许您选择安装程序先前已下载的VS Code压缩文件。该选项不是让您在机器上选择一个已安装VS代码的副本。
Create VS Code archives to share with other computers/OSes for offline install
This option downloads and saves a copy of VS Code for all platforms, which is useful for sharing with the installer for future offline installs.
Go ahead and select Download for this computer only. This will begin the download process and can take a bit depending on internet connectivity (it’s ~150MB). Once the download is done, select Next. You should be presented with a screen that looks similar to the one below.
备注
teams upgrading from Beta will already have a version of VS Code installed. However, it’s still recommended to select Download for this computer only to ensure the latest recommended version of VS Code is installed
安装完成后，将显示完成的界面。
重要
WPILib installs a separate version of VS Code. It does not use an already existing installation. Each year has it’s own copy of the tools appended with the year. IE: WPILib VS Code 2026. Please launch the WPILib VS Code and not a system installed copy!
恭喜，您的计算机上现已安装WPILib开发环境和工具！按完成退出安装程序。
安装后
某些操作系统需要某些最终操作才能完成安装。
安装后，安装程序将打开WPILib VS Code文件夹。将VS Code应用程序拖到扩展坞上。从桌面弹出WPILibInstaller映像。
Some versions of Linux (e.g. Ubuntu 22.04 and later) require you to give the desktop shortcut the ability to launch. Right click on the desktop icon and select Allow Launching.
Ubuntu 23.10 and later disable the kernel user namespaces feature for unknown applications. This means that the sandboxing feature won’t work on the WPILib VS Code. To enable sandboxing for the WPILib applications, AppArmor profiles are provided, and can be installed using the command below.
$ sudo cp ~/wpilib/YEAR/frccode/AppArmor/* /etc/apparmor.d/
$ sudo systemctl reload apparmor.service
The above will fix the following error:
The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that ~/wpilib/2026/advantagescope/chrome-sandbox is owned by root and has mode 4755.
备注
Installing desktop tools and rebooting will create a folder on the desktop called YYYY WPILib Tools, where YYYY is the current year. Desktop tool shortcuts are not available on Linux and macOS.
Additional C++ Installation for Simulation
C++ robot simulation requires that a native compiler to be installed. For Windows, this would be Visual Studio 2022 version 17.9 or later (not VS Code), macOS requires Xcode 14 or later, and Linux (Ubuntu) requires the build-essential package.
Ensure the Desktop Development with C++ option is checked in the Visual Studio installer for simulation support.
安装了什么？
脱机安装程序将安装以下组件：
** Visual Studio代码**-受支持的IDE，适用于2019及更高版本的机器人代码开发。即使您的计算机上已经安装了VS Code，脱机安装程序也会为WPILib开发设置单独的VS Code副本。这样做是因为，如果您将VS Code用于其他项目，则使WPILib安装程序起作用的某些设置可能会破坏现有的工作流程。
** C ++编译器**-用于为roboRIO构建C ++代码的工具链
** Gradle **-用于构建/部署C ++或Java机器人代码的Gradle的特定版本
** Java JDK / JRE **-Java JDK / JRE的特定版本，用于构建Java机器人代码并运行任何基于Java的工具（Dashboards等）。它与任何现有的JDK安装并存，并且不会覆盖JAVA_HOME变量
WPILib Tools - SmartDashboard, Shuffleboard, RobotBuilder, OutlineViewer, PathWeaver, Glass, SysId, Data Log Tool, roboRIO Team Number Setter, AdvantageScope, Elastic, WPIcal
** WPILib依赖项**-OpenCV等
VS Code Extensions - WPILib and Java/C++/Python extensions for robot code development in VS Code
Documentation - Offline copies of this frc-docs documentation and Java/C++/Python APIs
备注
It’s not recommended to use the VS Code Backup and Settings Sync feature to sync settings between a regular VS Code installation and the FRC VS Code installation. This could lead to either installation being broken.
卸载
WPILib旨在在不同的年份安装到不同的文件夹，因此在安装今年的WPILib之前不必卸载以前的版本。但是，如果需要，可以使用以下说明卸载WPILib。
Delete the appropriate wpilib folder (
c:\Users\Public\wpilib\YYYYwhereYYYYis the year to uninstall)删除``C：Users Public Public Desktop’’中的桌面图标
Delete the appropriate wpilib folder (
~/wpilib/YYYYwhereYYYYis the year to uninstall)
Delete the appropriate wpilib folder (
~/wpilib/YYYYwhereYYYYis the year to uninstall). egrm -rf ~/wpilib/YYYY
故障排除
In case the installer fails, please open an issue on the installer repository. A link is available here. The installer should give a message on the cause of the error, please include this in the description of your issue.
