python - djangocms : AttributeError: 'FileNotFoundError' object has no attribute 'cmd'

Question

我正在尝试安装Django CMS在 window 上。我正在使用以下步骤。

C:\Python34\Scripts\pip install djangocms-installer

E:\Projects\example>C:\Python34\Scripts\djangocms -p mysite mysite

但抛出以下错误:

Creating the project
Please wait while I install dependencies

During handling of the above exception, another exception occurred:

AttributeError: 'FileNotFoundError' object has no attribute 'cmd'

我已经搜索过，但找不到任何解决方案。

Answer 1

根本原因是这一行:

output = subprocess.check_output(['pip'] + args, stderr=subprocess.STDOUT)

因此将 PATH 放在 pip 可执行位置上，它应该可以工作:

set PATH=%PATH%;C:\Python34\Scripts

乍一看，这个包不太适合 Windows 环境...双重异常不太好，并且在没有任何路径的情况下调用 pip 可能会出现问题。
