在检查 pip3 版本时遇到“-bash: /usr/local/bin/pip3: /usr/bin/python3.6: bad interpreter: No such file or directory”

Question

我为当前的 python 版本安装了 pip3

$ python -V
Python 3.5.1+

我用这个命令来安装 pip3

sudo apt install python3-pip

当我尝试查看 pip 的版本时

$ pip3 -V 

我有

-bash: /usr/local/bin/pip3: /usr/bin/python3.6: bad interpreter: No such file or directory

之前我已经安装了python3.6并删除了它。

这是批准：

$ sudo apt remove python3.6
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'python3.6' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

这是我的 ${PATH}

$ echo ${PATH}
/home/user/.local/share/umake/bin:/home/user/.local/share/umake/bin:/home/user/.local/share/umake/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/snap/bin

如何修复当前 pip 的路径？

Answer 1

1. 运行命令which python3以显示 python3 可执行文件的路径。在步骤 2 中的命令中，我假设它是默认值/usr/bin/python3

2. 创建一个符号链接，在/usr/bin/python3.6其中引用 file /usr/bin/python3。

   sudo ln -s /usr/bin/python3 /usr/bin/python3.6
