导读：我正在尝试部署appengine flex python应用程序,但在部署后在Stackdriver日志stderr中获取以下内容 File "/env/local/lib/python2.7/site-packages/gunicorn/arbiter.py",line 578,in spawn_worker worker.init_process() File "/env/local/lib/python2.7/sit

我正在尝试部署appengine flex python应用程序,但在部署后在Stackdriver日志stderr中获取以下内容

File "/env/local/lib/python2.7/site-packages/gunicorn/arbiter.py",line 578,in spawn_worker
    worker.init_process()
  File "/env/local/lib/python2.7/site-packages/gunicorn/workers/base.py",line 126,in init_process
    self.load_wsgi()
  File "/env/local/lib/python2.7/site-packages/gunicorn/workers/base.py",line 135,in load_wsgi
    self.wsgi = self.app.wsgi()
  File "/env/local/lib/python2.7/site-packages/gunicorn/app/base.py",line 67,in wsgi
    self.callable = self.load()
  File "/env/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py",line 65,in load
    return self.load_wsgiapp()
  File "/env/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py",line 52,in load_wsgiapp
    return util.import_app(self.app_uri)
  File "/env/local/lib/python2.7/site-packages/gunicorn/util.py",line 352,in import_app
    __import__(module)
  File "/home/vmagent/app/my_service/entry_point.py",line 5,in <module>
    import flask_restful as restful
ImportError: No module named flask_restful

第5行的entry_point.py有

import flask_restful as restful

而我的requirements.txt有

Flask-RESTful==0.3.6
gunicorn==19.7.1

不知道为什么它还在抱怨Flask-Restful

解决方法

在某些平台上进口是 case sensitive,即Linux(Windows和Mac可能会或可能不关心案例). Flask-RESTful包并不像大多数软件包那样都是小写的(根据 PEP 8建议),因此将rest_restful作为restful导入会产生导入错误,除非使用了正确的大小写.
