python virtualenv（包装器）+ uwsgi + nginx（再次）

Question

好的，我知道那里有很多 virtualenv + uwsgi + nginx 文章，我已经阅读了大约 50 篇（我没有完整阅读 uWSGI 文档） .

我的问题：

为什么 none 这些选项实际上 activate 我要求它做的 virtualenv？

[uwsgi]
home = <path to python3 venv>
venv = <path to python3 venv>
virtualenv = <path to python3 venv>

但是我尝试了，我无法从默认的 python2.7 启动 uwsgi（已安装并正在运行），并且无法读取 uwsgi.ini、activate virtualenv，启动我的 django 项目。 uwsgi 也安装在 virtualenv 上。

所有其他内容（用户、组和权限）都已准备就绪，并且可以正常工作。

失败：从开始 virtualenv 活动：

$> uwsgi --ini uwsgi.ini

Answer 1

在第一种情况下，您似乎正在启动某种全局（可能与 sudo pip 一起安装）uwsgi，如输出所示：

detected binary path: /usr/local/bin/uwsgi

它可能缺少 python3 插件来正确切换环境，一般来说，我发现从 virtualenv 使用 uwsgi 总是更简单——它只是更频繁地工作。真的，不要费心尝试在系统范围内工作，使用你自己的。您将需要在另一个配置中添加完整路径，但这几乎不是问题。只需启动 /path/to/your/venv/bin/uwsgi 而不是 uwsgi.
