pythonanywhere corsheaders模块未找到错误

如何解决pythonanywhere corsheaders模块未找到错误

我将其设置如下，但是出现错误。 我需要你的帮助。

1. 在setting.py文件中设置corsheader
2. 已安装pip install django-cors-headers。
3. pip3 install django-cors-head已安装。

即使我们按照上面的方法进行处理，也存在如下错误。

pip3 cors-headers安装命令

pip3.7 install --user django-cors-headers      
Looking in links: /usr/share/pip-wheels
Requirement already satisfied: django-cors-headers in ./.local/lib/python3.7/site-packages (3.3.0)
Requirement already satisfied: Django>=2.0 in /usr/lib/python3.7/site-packages (from django-cors-headers) (2.1)
Requirement already satisfied: pytz in /usr/lib/python3.7/site-packages (from Django>=2.0->django-cors-headers) (2018.5)

解决方法

您的Web应用程序在虚拟环境myvenv中运行，但是您已使用.local标志将软件包安装在--user中。您需要在未激活--user虚拟环境的myvenv的情况下安装它。参见：https://help.pythonanywhere.com/pages/InstallingNewModules/
