使用pip安装包时出现异常。我试着安装了numpy，flask和其他软件。但是得到了低于错误。
C:\Users\ABC>pip install flask

Could not find a version that satisfies the requirement flask (from versions: )
No matching distribution found for flask请帮助解决它。Pip版本为18.1 Python版本为3.7

好吧，这是一个我总是遵循的黑客，但每次都有效-我需要这样做，因为我的公司网络背后是沉重的分层安全。
每次您需要安装pkgs时，请预先从cmd运行以下命令(您不需要是管理员)：
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>然后运行您常用的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通过您的网络信任pip：
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> --userStack Overflow用户

似乎对于当前发布的v1.0.2 Python3.7 is not supported yet。它的支持确实存在于master branch中，但尚未发布。
