python-pip在Arch Linux上似乎已损坏（没有名为'pip._vendor.retrying'的模块）

系统更新后，尝试调用pip（或pip3.7或pip3）时收到此错误：

  $ pip3.7

Other suggested solutions包含

  • ssl与此相关，但是python3 -c "import ssl"运行没有问题

  • python-requests可能会丢失，但是在那里。卸载和重新安装没有区别。

  • python-setuptools可能会丢失，但是在那里。卸载和重新安装没有区别。

  • pip uninstall pkg-resources==0.0.0，但这当然会失败，因为pip无法启动

  • 从curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3重新安装pip。我没有尝试。我宁愿不这样做，因为我认为它将以某种方式导致依赖性梦night

可能值得注意的是，我曾经有不同的python 3版本。我必须从AUR临时安装3.6，因为必须使用不能与3.7配合使用的软件。但是3.6版现在已经消失了，只剩下标准3.7版。

系统是Arch Linux 5.2.1，python是3.7.3。

答案 0 :(得分：2)

您可以尝试直接从pip（或python）重新安装损坏的python3，而不要使用系统软件包管理器（pacman）。请注意肯定有关Arch Linux，但对我来说，它解决了Ubuntu 16.04上的类似问题（ModuleNotFoundError: No module named 'pip._vendor.retrying'）：

$ sudo python -m pip install --upgrade pip
