ImportError: No module named 'django' uWSGI Django Nginx Ubuntu 16.04 Python3.6
ImportError: No module named 'django' uWSGI Django Nginx Ubuntu 16.04 Python3.6
我花了一天时间想弄明白。
我运行正在 Digital Ocean 与 Django、Python3.6、Nginx、Ubuntu 16.04 和 uWSGI.
必须通过 deadsnakesppa 安装 Python3.6 并且有一个 virtualenv 我用
创建的
mkvirtualenv --python=python3.6 myproject
我正在关注 this tutorial 我之前已经关注但是当我尝试 运行 下面的代码来测试应用程序服务器（不在 virtualenv 中）
uwsgi --http :8080 --home /home/user/Env/myproject --chdir /home/user/myproject/src/myproject -w myproject.wsgi
我得到这个回溯

我的项目显然需要 python3.6 到 运行 而我没有解决方案，任何人都可以提供任何建议吗？
如果您在系统上使用两个不同版本的 python（您的系统范围 python 似乎是 3.5.2），那么您应该 pip install uwsgi inside 包含您将要使用的 python 版本的 virtualenv。
然后你应该通过直接使用它的路径来启动那个特定的 uwsgi，在你的情况下/home/user/Env/myproject/bin/uwsgi：
> /home/user/Env/myproject/bin/uwsgi --ini /path/to/file/uwsgi.ini
或
> /home/user/Env/myproject/bin/uwsgi --http :8080 --home /home/user/Env/myproject --chdir /home/user/myproject/src/myproject -w myproject.wsgi
