Pip error -> ImportError: No module named helpers

Question

当我尝试使用 pip 安装任何包时出现错误。它显示 "ImportError: No module named helpers"。我尝试使用 pip 安装 helpers 模块，但发生了同样的错误。我正在粘贴错误消息的输出。操作系统：Arch Linux.

pip2 install requests

错误:

感谢大家的帮助。我找到了解决方案。当我升级到 python 时，3.7 点被破坏了。执行这些命令解决了问题。

rm -rf /usr/lib/python3.7/site-packages
python3.7 -m ensurepip
pip install --upgrade pip

同样可以与 Python2 一起使用，只需将 3.7 替换为 2.7，将 pip 替换为 pip2。
