关于autoware只复制文件，直接编译遇到的错误解决方法

1、只是在cpu状态下不能编译

colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release

显示colcon未找到命令
解决思路，应该装一个colcon
正常应该是装一个rosdep，命令

rosdep init
 rosdep update
 rosdep install -y --from-paths src --ignore-src -r

由于网络等原因不方便安装，换一种方法直接自己建立文件夹，将github上的内容复制进来进行保存。
遇见的问题：

ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.

解决办法：
也可以直接梯子装，下面是没有梯子的安装方法。

$ sudo mkdir -p /etc/ros/rosdep/sources.list.d
$ cd /etc/ros/rosdep/sources.list.d
$ sudo gedit 20-default.list
$ 将https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list中的内容复制粘贴到20-default.list中

https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list中的内容

# os-specific listings first
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx

# generic
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/ruby.yaml
gbpdistro https://raw.githubusercontent.com/ros/rosdistro/master/releases/fuerte.yaml fuerte

# newer distributions (Groovy, Hydro, ...) must not be listed anymore, they are being fetched from the rosdistro index.yaml instead

随后直接编译命令即可。
2、编译过程中出现的问题：
会出现丢包的状态，然后缺什么包安装什么包
举例问题：

--- stderr: lanelet2_io

这个错误信息表明 CMake 在构建 lanelet2_io 时无法找到 pugixml 库，导致构建失败。以下是解决这个问题的步骤：

安装 pugixml： 如果没有安装 pugixml，可以通过以下命令安装：

sudo apt-get install libpugixml-dev

以后的缺什么就按照这样装什么（可使用gpt帮忙操作）。
其余的我自己补全，每个人缺的东西可能不一样：

sudo apt-get install ros-melodic-jsk-recognition-msgs
sudo apt-get install ros-melodic-jsk-recognition-msgs
sudo apt-get install ros-melodic-jsk-rviz-plugins
sudo apt-get install libgeographic-dev
sudo apt-get install ros-melodic-nmea-msgs
sudo apt-get install libglew-dev
sudo apt-get install ros-melodic-nmea-navsat-driver
sudo apt-get install ros-melodic-grid-map-cv
sudo apt-get install ros-melodic-grid-map-msgs
sudo apt-get install ros-melodic-grid-map-ros
sudo apt-get install ros-melodic-automotive-navigation-msgs
sudo apt-get install ros-melodic-automotive-platform-msgs
sudo apt-get install ros-melodic-velodyne-pointcloud
sudo apt-get install ros-melodic-qpoases-vendor
