我花了一天的时间来解决这个问题。
我在Digital Ocean上与Django，Python3.6，Nginx，Ubuntu 16.04和uWSGI一起运行。
必须通过Python3.6安装deadsnakesppa并拥有我用
virtualenv
mkvirtualenv --python=python3.6 myproject
我正在遵循之前遵循的this tutorial，但是当我尝试运行以下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
我得到了此追溯

激活virtualenv时，我会得到相同的结果。

如果我运行以下命令（不在virtualenv内部）
python3 -c 'import django.core.wsgi'
我知道
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named 'django'
但是如果我在virtualenv中运行它，则不会收到任何错误，这意味着该错误与uWSGI有关。
从我的python manage.py runserver级别运行manage.py很好。
pip3 -V给出pip 19.2.1 from /home/user/.local/lib/python3.6/site-packages/pip (python 3.6)
和python3.6 -V给出Python 3.6.9
我尝试使用sudo -H pip3 install uwsgi重新安装uWSGI，并且它似乎总是安装到python 3.5 site-packages。
如果我在virtualenv中运行pip3 install uwsgi，它将安装到

我的项目显然需要python3.6才能运行，而我没有解决方案，有人可以提供任何建议吗？
答案 0 :(得分：1)
如果您在系统上使用两种不同版本的python（您的系统范围内的python似乎是3.5.2），则应pip install uwsgi 内部包含以下内容的virtualenv您将要使用的python版本。
然后，您应该直接使用指向特定路径的 uwsgi启动 / home / user / Env / myproject / bin / uwsgi ：< / p>
> /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
