Ubuntu 18.04下安装ROS小记

 

一开始遇到

sudo apt-get install ros--desktop-full (E: Unable to correct problems, you have held broken packages.)

 

多方搜索之后，先使用apt-get安装aptitude

sudo apt-get install aptitude

 

然后使用aptitude安装对应的ros

sudo aptitude install ros-desktop-full

 

接着是配置下zshrc

echo "source /opt/ros/melodic/setup.zsh" >> ~/.zshrc source ~/.zshrc

如果你用的是bashrc，则是

echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc source ~/.bashrc

 

接着是配置依赖

sudo apt install python-rosdep python-rosinstall python-rosinstall-generator python-wstool build-essential

 

进行初始化

sudo rosdep init rosdep update

 

初始化的时候遇到错误

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.

 

下载并配置proxychains来解决

sudo apt-get install proxychains

 

然后编辑配置文件，在文件末尾处，将内容改为自己的代理地址以及端口

sudo vi /etc/proxychains.conf

 

之后执行

sudo proxychains rosdep init

proxychains rosdep update

注意后面update的时候不要加sudo，不然会有权限问题
