【问题描述】：

我设置如下，但有错误。我需要你的帮助。

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

虽然我们按照上面的方式处理了，但还是有如下错误。

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)

【解决方案1】：

您的 Web 应用程序在虚拟环境 myvenv 中运行，但您在 .local 中安装了带有 --user 标志的包。您需要在没有--user 的情况下安装它并激活myvenv 虚拟环境。见：https://help.pythonanywhere.com/pages/InstallingNewModules/
