:
python -m pip install -U pyyaml setuptools
下载ROS2
-
ROS2的相关下载链接:https://github.com/ros2/ros2/releases
-
下载适用于Windows的最新软件包,例如
ros2-package-windows-AMD64.zip
。- 注意:可能有多个二进制下载选项可能导致文件名不同。
-
解压缩zip文件(我们假设

)。
设置ROS2的环境
- 执行以下命令以及source RO2的配置文件来设置工作空间
call C:\dev\ros2\local_setup.bat
-
如果您下载了具有OpenSplice支持的版本并希望将其用作中间件,则必须另外获取OpenSplice安装文件。只有这样

ros2 run demo_nodes_cpp talker
- 打开一个新终端,执行以下命令:
ros2 run demo_nodes_py listener
- 运行结果图如下:
排除故障
-
如果不能运行例子且出现缺少dll的报错,请检查前面安装的外部依赖的所有的库,例如:OpenCV的
PATH
环境变量是否设置正确 -
如果前面在设置时忘记执行
call C:\dev\ros2\local_setup.bat
命令,则可能无法运行演示

Installing ROS 2 on Windows¶
Table of Contents
This page explains how to install ROS 2 on Windows from a pre-built binary package.
System requirements¶
As of beta-2 only Windows 10 is supported.
Installing prerequisites¶
Install Chocolatey¶
Chocolatey is a package manager for Windows, install it by following their installation instructions:
You’ll use Chocolatey to install some other developer tools.
Install Python¶
Open a Command Prompt and type the following to install Python via Chocolatey:
> choco install -y python
Install OpenSSL¶
Download an OpenSSL installer from this page. Scroll to the bottom of the page and download Win64 OpenSSL v1.0.2. Don’t download the Win32 or Light versions.
Run the installer with default parameters. The following commands assume you used the default installation directory:
-
setx -m OPENSSL_CONF C:\OpenSSL-Win64\bin\openssl.cfg
You will need to append the OpenSSL-Win64 bin folder to your PATH. You can do this by clicking the Windows icon, typing “Environment Variables”, then clicking on “Edit the system environment variables”. In the resulting dialog, click “Environment Variables”, then click “Path” on the bottom pane, finally click “Edit” and add the path below.
-
C:\OpenSSL-Win64\bin\
Install Visual Studio¶
Install Visual Studio 2019.
If you already have a paid version of Visual Studio 2019 (Professional, Enterprise), skip this step.
Microsoft provides a free of charge version of Visual Studio 2019, named Community, which can be used to build applications that use ROS 2:
Make sure that the Visual C++ features are installed.
An easy way to make sure they’re installed is to select the Desktop development with C++
workflow during the install.
Make sure that no C++ CMake tools are installed by unselecting them in the list of components to be installed.
Install additional DDS implementations (optional)¶
ROS 2 builds on top of DDS. It is compatible with multiple DDS or RTPS (the DDS wire protocol) vendors.
The package you downloaded has been built with optional support for multiple vendors: eProsima FastRTPS, Adlink OpenSplice, and RTI Connext as the middleware options. Run-time support for eProsima’s Fast RTPS is included bundled by default. If you would like to use one of the other vendors you will need to install their software separately.
Adlink OpenSplice¶
If you want to use OpenSplice, you will need to download the latest supported version. For ROS 2 Dashing version 6.9.190403OSS-HDE-x86_64.win-vs2017 or later is required.
After unpacking, set the OSPL_HOME
environment variable so that it points to the directory that contains the release.bat
script.
RTI Connext¶
To use RTI Connext DDS there are options available for university, purchase or evaluation
After installing, run RTI launcher and point it to your license file.
Set the NDDSHOME
environment variable:
set "NDDSHOME=C:\Program Files\rti_connext_dds-5.3.1"
If you want to install the Connext DDS-Security plugins please refer to this page.
Install OpenCV¶
Some of the examples require OpenCV to be installed.
You can download a precompiled version of OpenCV 3.4.6 from https://github.com/ros2/ros2/releases/download/opencv-archives/opencv-3.4.6-vc16.VS2019.zip .
Assuming you unpacked it to C:\opencv
, type the following on a Command Prompt (requires Admin privileges):
setx -m OpenCV_DIR C:\opencv
Since you are using a precompiled ROS version, we have to tell it where to find the OpenCV libraries. You have to extend the PATH
variable to C:\opencv\x64\vc16\bin
.
Install dependencies¶
There are a few dependencies not available in the Chocolatey package database. In order to ease the manual installation process, we provide the necessary Chocolatey packages.
As some chocolatey packages rely on it, we start by installing CMake
> choco install -y cmake
You will need to append the CMake bin folder C:\Program Files\CMake\bin
to your PATH.
Please download these packages from this GitHub repository.
-
asio.1.12.1.nupkg
-
eigen-3.3.4.nupkg
-
tinyxml-usestl.2.6.2.nupkg
-
tinyxml2.6.0.0.nupkg
-
log4cxx.0.10.0.nupkg
Once these packages are downloaded, open an administrative shell and execute the following command:
> choco install -y -s <PATH\TO\DOWNLOADS\> asio eigen tinyxml-usestl tinyxml2 log4cxx
Please replace <PATH\TO\DOWNLOADS>
with the folder you downloaded the packages to.
You must also install some python dependencies for command-line tools:
python -m pip install -U catkin_pkg empy lark-parser lxml numpy opencv-python pyparsing pyyaml setuptools
RQt dependencies¶
python -m pip install -U pydot PyQt5
Downloading ROS 2¶
-
Go the releases page: https://github.com/ros2/ros2/releases
-
Download the latest package for Windows, e.g.,
ros2-dashing-*-windows-AMD64.zip
.
Note
There may be more than one binary download option which might cause the file name to differ.
Note
To download the ROS 2 debug libraries you’ll need to download ros2-dashing-*-windows-debug-AMD64.zip
-
Unpack the zip file somewhere (we’ll assume
C:\dev\ros2
).
Set up the ROS 2 environment¶
Start a command shell and source the ROS 2 setup file to set up the workspace:
> call C:\dev\ros2\local_setup.bat
It is normal that the previous command, if nothing else went wrong, outputs “The system cannot find the path specified.” exactly once.
Try some examples¶
In a command shell, set up the ROS 2 environment as described above and then run a talker
:
> ros2 run demo_nodes_cpp talker
Start another command shell and run a listener
:
> ros2 run demo_nodes_py listener
You should see the talker
saying that it’s Publishing
messages and the listener
saying I heard
those messages. Hooray!
If you have installed support for an optional vendor, see this page for details on how to use that vendor.
Troubleshooting¶
-
If at one point your example would not start because of missing dll’s, please verify that all libraries from external dependencies such as OpenCV are located inside your
PATH
variable. -
If you forget to call the
local_setup.bat
file from your terminal, the demo programs will most likely crash immediately. -
If you see an error related with FastRTPS failing to be loaded, see troubleshooting section in development install instructions.
Build your own packages¶
If you would like to build your own packages, refer to the tutorial "Using Colcon to build packages".
