Windows上的PyCharm：無法將“ django-admin”識別為內部或外部命令

Question

當我嘗試安裝Django時，PyCharm的控制台向我顯示：

(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'

但是當我運行pip freeze ，它顯示了我：

(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

雖然我無法啟動項目：

(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.

我怎樣才能解決這個問題？ 我正在Windows和Python 3.x上運行PyCharm 2016。

謝謝，

您應該使用虛擬環境。 （virtualenv）您需要在啟動PyCharm之前激活虛擬環境，並且需要在激活虛擬環境的命令提示符下啟動PyCharm。

激活virtualenv時，它會將條目添加到您的Shell（cmd）的PATH中，並且從該Shell啟動的任何程序都將繼承該Shell的PATH。 通過在激活的virtualenv中啟動編輯器，它將找到正確的python和正確的django-admin。

由於環境已激活，您還可以從cmd提示符下執行django-admin。

您可以在virtualenv上閱讀以找到激活腳本，該腳本會將cmd提示符置於正確的思路中，以使所有這些工作正常進行。
