我在/home/stephane/programs/install/bin/目录中安装了一个nvim应用程序。
我还删除了以前的安装：sudo apt-get remove neovim
但我只能用绝对路径运行：
stephane@stephane-pc:~$ echo $PATH

stephane@stephane-pc:~$ nvim --version
bash: /usr/bin/nvim: No such file or directory
当试图用相对路径运行它时，也就是说，只使用命令名，它找不到它
更新：类型显示：
stephane@stephane-pc:~$ type -a nvim
nvim is /home/stephane/programs/install/bin/nvim
您的命令nvim似乎只安装在本地文件夹中。如果您想将其与命令名一起使用：
/home/stephane/programs/install/bin/应该添加到您的$PATH中(但您似乎已经尝试过了(
或
nvim应安装在适当的目录中，例如已经在$PATH中的/usr/local/bin/
您可以尝试执行符号链接：ln -s /home/stephane/programs/install/bin/nvim /usr/local/bin/还是尝试执行/usr/bin/中的符号链接
有帮助吗？
我刚刚获取了.bashrc文件，它解决了这个问题。
它显示了需要刷新的PATH环境变量。
stephane@stephane-pc:~$ source ~/.bashrc
stephane@stephane-pc:~$ nvim --version
NVIM v0.6.1
