ImportError:没有名为flask_restful的模块

Question

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

Answer 1

导入错误：没有名为 flask_restful 的模块

似乎你没有安装flask_restful，安装运行：

pip install flask-restful

在您的终端中，然后运行您的应用程序。

进口在某些平台上是区分大小写的,即Linux(Windows和Mac可能会或可能不关心大小写).Flask-RESTful软件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import flask_restful as restful除非使用正确的大小写,否则会产生导入错误.
