我该怎么办？

Answer 1

权限被拒绝错误通常是由要加载的文件或导致该文件的子目录之一的所有者，组或文件模式设置不正确引起的。 另一个可能的原因是SELinux，但前提是已启用它并且处于强制模式。

Permission denied: '/root/.local/share/virtualenvs/movie_douban-og6kh8C1/bin/activate_this.py'

在这种情况下，几乎可以肯定，Apache进程无法访问/root目录（即admin的主目录），因为它在apache或httpd用户的UID下运行。

您应该将virtualenv文件移动到更合适的位置。
