每次打开 Ubuntu 终端时，Bash 均提示没有该文件或目录

我是 Ubuntu 新手。我试图添加：

echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc

然后我重新加载了 .bashrc ：

source ~/.bashrc

现在我被这个问题困住了。每次我启动终端时，我首先都会得到这个：

截图＃1

bash: /catkin_ws/devel/setup.bash: No such file or directory
bash: /home/ros/Home/catkin_ws/devel/setup.bash: No such file or directory

编辑：cat ~/.bashrc我得到以下内容（文件的最后一行）：

else 
    if [ -f "/home/ros/anaconda3/etc/profile.d/conda.sh" ]; then 
        ."/home/ros/anaconda3/etc/profile.d/conda.sh"
    else 
        export PATH="/home/ros/anaconda3/bin:$PATH" 
    fi
fi
unset __conda_setup 
# <<< conda initialize <<<

source /opt/ros/noetic/setup.bash 
source /catkin_ws/devel/setup.bash 
source ~/catkin_ws/devel/setup.bash 
source ~/catkin_ws/devel/setup.bash 
source ~/catkin_ws/devel/setup.bash 
source ~/Home/catkin_ws/devel/setup.bash 
source ~/catkin_ws/devel/setup.bash 
source ~/catkin_ws/devel/setup.bash 
source ~/catkin_ws/devel/setup.bash

并ls ~/catkin_ws/devel给出：

cmake.lock  local_setup.bash  setup.bash      setup.zsh
env.sh      local_setup.sh    setup.sh        share
lib         local_setup.zsh   _setup_util.py

好的，看一下你的结尾.bashrc，你能看到问题吗？

看起来您尝试执行该命令echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc多次，但其中一些命令包含错误。

您需要做的是编辑您的~/.bashrc文件，例如使用 nano：

nano ~/.bashrc

现在，删除末尾（之后）所有不需要的行# <<< conda initialize <<<。我假设您还需要文件/opt/ros/noetic/setup.bash，因此保留以下几行：

source /opt/ros/noetic/setup.bash 
source ~/catkin_ws/devel/setup.bash
