django,pyenv,uwsgi - ModuleNotFoundError:没有名为'django'的模块

问题描述 投票:3回答:4

我在/etc/uwsgi/vassals/gsd.ini中有以下附庸配置:

[uwsgi]
plugins = python
env = DJANGO_SETTINGS_MODULE=%n.settings
virtualenv = /home/toogy/.pyenv/versions/%n
chdir = /home/webapps/%n
module = %n.wsgi:application
master = true
vacuum = true
pidfile = /tmp/uwsgi-%n.pid
socket = /tmp/uwsgi-%n.sock
daemonize = /var/log/uwsgi/%n.log
chmod-socket = 666
uid = toogy
gid = toogy

这是我得到的uwsgi日志

它找不到django,我不知道为什么因为uwsgi似乎检测到python环境(安装了django)。

此外,它说Python version: 3.6.0而我的virtualenv Python版本是3.5.2。我不知道这是否应该发生。系统Python版本是3.6.0。

我正在使用uwsgiuwsgi-plugins-python Arch Linux官方软件包的最新版本。

python django uwsgi pyenv

问题是链接到uwsgi的系统级python版本需要与virtualenv相同,我认为这是一个非常愚蠢的事情。

gsd.ini看看这个:

virtualenv = /home/toogy/.pyenv/versions/%n

你有没有在这个virtualenv下安装django

我还发现了一些我想分享的陷阱:

  • 检查,如果virtualenv(与venvpyhomehome相同)设置为该目录,其中包含binincludelib,...目录
  • 检查,如果用户(uid)可以读取项目中的文件和虚拟环境中的库(这以ModuleNotFoundError而不是权限错误结束)
  • 使用need-app退出失败(这有助于调试,应该是默认的imho)
  • 使用strict来避免配置中的拼写错误(这也应该是默认的...)
  • 如果您的test.py运行,请尝试导入项目模块和虚拟环境,以测试是否有效。它还有助于添加一个 import sys print(sys.path)

您还可以复制打印的sys.path,打开python shell并将sys.path设置为相同的值并尝试导入所需的wsgi模块。

在我的情况下,它使用系统范围的uwsgi,我正在使用virtualenv,所以如果我执行

$ which uwsgi

我得到了/usr/local/python3.6/bin/uwsgi

正如Valentin Iovene建议您需要使用虚拟环境中的uwsgi

我的目录结构是这样的:

~/Env
--/app
--/bin
----/....
----/uwsgi <-- This should be the good one
----/...
--/include
--/lib

(app目录是我的django app所在的位置)

在我的情况下,uwsgi文件没有执行权限,所以我只执行:

$ chmod +x ~/Env/bin/uwsgi

最后在我的app目录下,我执行了uwsgi命令,如下所示:

../bin/uwsgi --http :8000 --module app.wsgi

现在我可以看到我的应用程序正在运行:)

我正在遵循这个指南:https://uwsgi-docs.readthedocs.io/en/latest/tutorials/Django_and_nginx.html

接下来的步骤是配置nginx和https ...

我知道这是一个迟到的回应,但希望这有助于并分享对我有用的东西。
