ModuleNotFoundError: No module named 'pip.download' when trying to install Python package for Django

Question

尝试使用 pip 安装 Numpy 和其他包时。我收到一条消息说 ModuleNotFoundError: No module named 'pip.download'。任何人都知道任何可能的解决方案吗？我目前运行 Python3。我看过类似的问题，但似乎没有解决方案。例如。 "pip install unroll": "python setup.py egg_info" failed with error code 1

pip3 install 'django-numpy==1.0'
Collecting django-numpy==1.0

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

        from pip.download import PipSession
    ModuleNotFoundError: No module named 'pip.download'

Answer 1

如果您希望使用此代码 from pip.download import PipSession 更新旧的 Python 包，此代码段可以替换它

try:  # pip >= 10
    from pip._internal.download import PipSession
except ImportError:  # pip <= 9.0.3
    from pip.download import PipSession
