Command 'vcs' not found, did you mean

已经成功执行

pip install -U colcon-common-extensions vcstool

但是执行如下命令时报错：

vcs import src < fastrtps.repos

Command 'vcs' not found, did you mean:
...
Try: sudo apt install <deb name>

原因

pip install 可能把 vcs 安装到了 ~/.local/bin/

解决方案

运行如下命令，修改 PATH 环境变量

PATH=$PATH:~/.local/bin
