Windows 上的 PyCharm：'django-admin' 未被识别为内部或外部命令

Question

当我尝试安装 Django 时，PyCharm 的控制台显示：

(my_env) C:\projects\app\web>pip install django==1.8.6
You are using pip version 7.1.0, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip'    command.
Collecting django==1.8.6

raise DistlibException('Unable to locate finder for %r' % package)
pip._vendor.distlib.DistlibException: Unable to locate finder for 'pip._vendor.distlib'

但是当我运行pip freeze 时，它显示了我：

(my_env) C:\projects\app\web>pip freeze
You are using pip version 7.1.0, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
Django==1.8.6
wheel==0.24.0

虽然我无法启动项目：

(my_env) C:\projects\app\web>django-admin startproject mysite
'django-admin' is not recognized as an internal or external command,
operable program or batch file.

我该如何解决这个问题？我在 Windows 和 Python 3.x 上运行 PyCharm 2016。

谢谢，

您应该使用虚拟环境。 (virtualenv) 在启动 PyCharm 之前，您需要激活您的虚拟环境，并且您需要从激活虚拟环境的命令提示符处启动 PyCharm。

当您激活 virtualenv 时，它会将条目添加到您的 shell (cmd) 的 PATH 中，并且从此 shell 启动的任何程序都会继承 shell 的 PATH。通过在激活的 virtualenv 中启动编辑器，它会找到正确的 python 和正确的 django-admin。

由于激活了环境，你也可以在cmd提示符下执行django-admin。

您可以阅读 virtualenv 以找到激活脚本，该脚本将使您的 cmd 提示符处于正确的思维框架中以使所有这些工作。
