Question

我正在尝试部署appengine flex python应用程序，但部署后在Stackdriver log stderr中得到以下内容

  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行中的

entry_point.py具有

import flask_restful as restful

我的require.txt有

Flask-RESTful==0.3.6
gunicorn==19.7.1

不确定为什么它仍然抱怨Flask-Restful

Answer 1

导入是在某些平台上case sensitive的，即Linux（Windows和Mac可能或可能不关心大小写）。包Flask-RESTful并不像大多数包一样都是小写的（按照PEP 8的建议），因此，import flask_restful as restful会产生导入错误，除非使用适当的大小写。

Answer 2

ImportError：没有名为flask_restful的模块

似乎没有安装 flask_restful 来安装运行：

pip install flask-restful

在您的终端中，然后运行您的应用。

我遇到了同样的问题...我正在使用Visual Studio Code的“播放”按钮运行应用程序，并被卡住。一切都已经安装好了... 一段时间后，我意识到必须使用IDE的控制台并从那里启动程序：

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {


    setHasOptionsMenu(true);

    View view = inflater.inflate(R.layout.fragment_cgpa_frag, container, false);
    recyclerview = (RecyclerView) view.findViewById(R.id.rc2);
    cgpaArrayList = new ArrayList<>();
    //put this method here
    Fetchdata2();
    ac = new adapter_cgpa(cgpaArrayList);
    recyclerview.setLayoutManager(new LinearLayoutManager(getContext(), RecyclerView.VERTICAL, false));
    recyclerview.setAdapter(ac);



    return view;
}

private void Fetchdata2() {
    dbmanager db = new dbmanager(getContext());

    Cursor cursor = db.fetch_data2();

    if (cursor != null) {

        // cursor.moveToFirst();
        while (cursor.moveToNext()) {

            POJO pj = new POJO();
            pj.setCname(cursor.getString(0));
            pj.setNo_of_sems(cursor.getString(1));
            pj.setCgpa(cursor.getString(2));
            pj.setPercentage(cursor.getString(3));
            pj.setSchemec(cursor.getString(4));
            cgpaArrayList.add(pj);
        }

    }

}

我在虚拟环境

下运行它

Answer 4

基本上，您的项目根目录与python不匹配此特定（flask_restful）软件包的根目录，
卸载python应用程序并将其重新安装在窗口程序文件中，您应该在您的Windows程序中单独安装python

我通过此过程（满意的编码）解决了

ImportError：没有名为flask_restful的模块
