使用pip安装软件包时发生异常。我尝试安装numpy,flask和其他人。但低于错误。
C:\Users\ABC>pip install flask

请帮忙解决它。 Pip版本是18.1 Python版本是3.7
好吧,这是一个我总是遵循但每次都有效的黑客 - 我需要这样做,因为我的公司网络背后是分层安全。
每次需要安装pip pkgs时,请事先从cmd运行以下命令(您不需要是Admin):
set http_proxy=http://your_corp_username:password@<your_corp_proxy_host>:<port>
set https_proxy=https://your_corp_username:password@<your_corp_proxy_host>:<port>
然后运行您通常的pip命令。
如果pip抛出一些SSL信任/解析错误。您还可以执行以下操作来信任您的网络点:
pip --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org install <some_package>
使用以下命令仅在当前用户下安装软件包(这不需要管理员权限)
pip --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org install <some_package> --user
你的“f”应该是“F”:
pip install Flask
似乎对于当前发布的v1.0.2 Python 3.7 is not supported yet。它的支持确实存在于master branch,但尚未发布。
