弹性豆茎上的 RuntimeError("populate() is not reentrant")

Question

我在 Elastic Beanstalk 上运行 django，在推送新版本的应用程序后，我收到 500 内部服务器错误。

日志显示：

     apps.populate(settings.INSTALLED_APPS)
   File "/opt/python/run/venv/local/lib/python3.6/site-packages/django/apps/registry.py", line 83, in populate
     raise RuntimeError("populate() isn't reentrant")
 RuntimeError: populate() isn't reentrant
 mod_wsgi (pid=21994): Target WSGI script '/opt/python/current/app/wsgi.py' cannot be loaded as Python module.
 mod_wsgi (pid=21994): Exception occurred processing WSGI script '/opt/python/current/app/wsgi.py'.
 Traceback (most recent call last):
   File "/opt/python/current/app/wsgi.py", line 16, in <module>
     application = get_wsgi_application()
   File "/opt/python/run/venv/local/lib/python3.6/site-packages/django/core/wsgi.py", line 12, in get_wsgi_application
     django.setup(set_prefix=False)
   File "/opt/python/run/venv/local/lib/python3.6/site-packages/django/__init__.py", line 24, in setup

对调试有什么建议吗？到目前为止，我试图理解它/谷歌它没有成功。

这通常发生在解释器无法加载源代码（前提是您已经运行）或（如果您正在部署）它指出了一个配置问题，主要与尝试加载相同解释器的线程数有关。

我建议您硬重启运行应用程序的服务。这很可能会解决它。如果错误仍然存​​在，请检查您的 wsgi 配置。
