问题分析

系统是Manjaro Linux，pip是通过包管理器pacman安装的，这个应该是包管理器安装的pip出现了问题。

卸载试试。看看能不能在安装后换回包管理器版本的pip，因为这样子系统很干净。

解决方案

卸载pip sudo pacman -R python-pip

下载最新的pip源码包当前为10.0.1，wget https://files.pythonhosted.org/packages/ae/e8/2340d46ecadb1692a1e455f13f75e596d4eab3d11a57446f08259dee8f02/pip-10.0.1.tar.gz

解压tar -zxvf pip-10.0.1.tar.gz && cd pip-10.0.1

安装pipsudo python3 setup.py install

安装pip完成

如果你没有系统洁癖，强迫症到这里就完成了。

这样子安装的pip无法通过包管理器完成更新，每次需要手动更新。

卸载pipsudo python -m pip uninstall pip

重新安装pipsudo pacman -S python-pip
