使用pip安装软件包时发生异常。我尝试安装numpy，flask等。但出现错误。

Answer 1

好吧，这是我始终会遵循的骇客方式，但每次都能奏效-我需要这样做，因为我的公司网络背后存在沉重的分层安全性。

每次您需要安装pip pkgs时，请从cmd预先运行以下命令（无需成为管理员）：

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的点子：

pip --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org install <some_package>

使用以下内容仅在当前用户下安装软件包（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

Answer 2

It seems that for current release v1.0.2 Python 3.7 is not supported yet. Its support does exist in the master branch, but not yet released.

您的“ f”应为“ F”：
