Question

我已经在flask中编写了一个网站，它可以在调试服务器上完美运行，但是当部署在uwsgi和nginx的组合上时，它无法从命令行运行任何命令。例如，脚本的一个部分尝试访问它无法找到它的os.environ['HOME']。其中一个脚本尝试运行命令行程序，但它再次抱怨无法找到它。我以我的用户身份运行nginx，我绝对可以看到并使用所有这些内容。

我猜测uwsgi或nginx在＆＃39;空间＆＃39;那是无法看到操作系统或什么的？我怎样才能改变它或绕过它呢？

错误如下（这些是从烧瓶站点的新python线程开始的，所以这可能很重要）

环境变量的回溯：

Flask，uwsgi，nginx无法访问操作系统级命令
