ROS2-IRON Ubuntu-22.0 源码下载失败解决方法 vcs import --input

一.ROS2 IRON环境搭建

虚拟机系统：Ubuntu22.04
虚拟机：VMware-player-full-16.2.5-20904516 （这个是非商用就可以免费使用的哦）
电脑系统：WIN10
以下操作都是在虚拟机下的Ubuntu22.04环境中。
详细步骤参考ROS2官网：

1.设置系统字符集为UTF-8

locale  # check for UTF-8

sudo apt update && sudo apt install locales
sudo locale-gen en_US en_US.UTF-8
sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
export LANG=en_US.UTF-8

locale  # verify settings

2.将RO2 apt 库添加到系统中

sudo apt install software-properties-common
sudo add-apt-repository universe

3.添加ROS2 GPG key

sudo apt update && sudo apt install curl -y
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg

4.添加ROS 2 的软件源

这个命令的作用是将 ROS 2 的软件源添加到/etc/apt/sources.list.d/ros2.list 文件中。这样系统就可以从这个源中获取 ROS 2 相关的软件包。

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(. /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null
1

安装开发工具

sudo apt update && sudo apt install -y \
  python3-flake8-docstrings \
  python3-pip \
  python3-pytest-cov \
  python3-flake8-blind-except \
  python3-flake8-builtins \
  python3-flake8-class-newline \
  python3-flake8-comprehensions \
  python3-flake8-deprecated \
  python3-flake8-import-order \
  python3-flake8-quotes \
  python3-pytest-repeat \
  python3-pytest-rerunfailures \
  ros-dev-tools

二.下载ROS2sh源代码

创建ros2_iron/src目录，并下载相关源码。

mkdir -p ~/ros2_iron/src
cd ~/ros2_iron
vcs import --input https://raw.githubusercontent.com/ros2/ros2/iron/ros2.repos src

这一步我尝试了很多方法，各种换源。但是因为电脑不能翻墙的原因，一直下失败。我的解决方法是在浏览器中访问

url对应的就是github上所在的源代码。把github上的这些源代码仓库转移到gitee上，这个gitee提供了这一部分的功能。
在ros2_iron路径下，用vim新建ros2.repos文件。

vim ros2.repos 
1

vim 在normal模式下，输入"+p将https://raw.githubusercontent.com/ros2/ros2/iron/ros2.repos中的内容复制到本地（前提是已经复制到系统内存中了，才能使用这个命令）。用vim查找替换url地址。

:%s/https\/\/github.com\/\(.*\)\//gitee.com:makuswork\//g

这样本地中ros2.repos中的url中的内容全部修改成我自己的gitee仓库中了。我把地址改成了ssh的通信。下载源代码时就不用一直的输入帐号和密码了。保存关闭。

在ros2_iron路径下

vcs import --input ros2.repos src

编译

sudo apt upgrade

sudo rosdep init
rosdep update
rosdep install --from-paths src --ignore-src -y --skip-keys "fastcdr rti-connext-dds-6.0.1 urdfdom_headers"

如果编译报错，EasyInstallDeprecationWarning，可以参考colcon build --symlink-install ,编译失败解决方法
