全局 gunicorn 和 pipenv 虚拟环境：ModuleNotFoundError: No module named 'django'

Question

我想只在全球范围内安装 gunicorn（apt-get gunicorn3，Ubuntu 18.04），但要识别我由 pipenv 管理的虚拟环境。

这行得通 - 本地独角兽：

# install dependencies from requirements.txt
$ pipenv install

# add local gunicorn
$ pipenv install gunicorn

# run the app, using local gunicorn
$ gunicorn my-site.wsgi:application

这行不通，这才是我真正需要的：

# install dependencies from requirements.txt
$ pipenv install

# activate the virtual environment
$ pipenv shell

# run the app, using global gunicorn
$ gunicorn3 my-site.wsgi:application

Error:

由于我在同一服务器中有多个 python 应用程序，其中一些无法修改为需要 gunicorn，因此能够全局运行 gunicorn3 并使用pipenv 启动多个应用程序将非常方便。

我缺少什么能够在全球范围内运行 gunicorn 但仍然加载安装在虚拟环境中的包？

Answer 1

运行

pipenv run gunicorn my-site.wsgi:application

而不是

gunicorn my-site.wsgi:application
