Question

我正在尝试安装以下依赖项：

appdirs==1.4.3
click==6.7
Flask==1.0
itsdangerous==0.24
Jinja2==2.10.1
MarkupSafe==1.0
packaging==16.8
prometheus-client==0.0.19
pyparsing==2.2.0
Werkzeug==0.15.3

但是无论我尝试安装哪个依赖项，都会出现以下错误：

Traceback (most recent call last):
  File "/usr/bin/pip", line 11, in <module>
    load_entry_point('pip==19.3', 'console_scripts', 'pip')()

    from pip._vendor.six import ensure_binary
ImportError: cannot import name 'ensure_binary' from 'six' (/usr/lib/python3.8/site-packages/six.py)

出了什么问题？

在此将答案专门发布给使用Manjaro Linux的人（不建议使用pip，因为如果使用不正确，可能会破坏环境）。它还可能导致后续发行版更新无法无缝发生，并可能导致需要人工干预。

消除环境损害的解决方案是使用：

sudo pacman -Syu python-pkgname --overwrite='*'

其中pkgname是要安装的python依赖项的名称。完成此操作后，应该修复环境，然后不再需要应用--overwrite选项。

整个Python 2和Python 3以及由此产生的pip2和pip3工具分离是疯狂的。
