我已经尝试了这个 PIP 损坏问题的所有方法

每次我遇到这个问题时，我只是复制我的文件并安装新的kali副本，然后再次更新系统并复制重新下载我的应用程序的要求，我不知道它到底发生在哪里或何时，唯一的解决方法是使用环境活跃 pip3 工作正常

root@kali:~# which pip
/usr/local/bin/pip
root@kali:~# whereis pip
pip: /usr/bin/pip /usr/local/bin/pip /usr/local/bin/pip2.7 
/usr/share/man/man1/pip.1.gz



root@kali:~# pip

如果 pip 搞砸了。那么最好的选择是使用您在发行版上安装 python 时使用的相同软件包系统来重新安装它。

下一步是获取蟒蛇环境使用以下方法自行修复：

python -m ensurepip

python -m ensurepip --upgrade

如果失败你可以尝试引导脚本- 用curl获取它：

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

然后执行：

python get-pip.py
