将 pip 从 /usr/local/bin/pip 切换到 /usr/bin/pip

Question

我通过/usr/local/bin/pip执行sudo python3 -m pip install -U pip命令强制启动 pip 。

现在我想使用 pip from/usr/bin/pip

为了实现这一点，我将点重命名为/usr/local/bin/pip_backup

现在在我问，which pip或者which pip -a它只显示/usr/bin/pip。

但我无法使用 pip 下载或安装任何包。它说：

[root@localhost file_name]# pip install snips-nlu

-bash: /usr/local/bin/pip: No such file or directory
some relevant

[root@localhost bot_v4.0]# which python -a /usr/bin/python 

[root@localhost bot_v4.0]# which pip -a /usr/bin/pip
