Python external on Azure ImportError No Module Fou

2019-08-21 02:56发布

If i locally run my code with python main.py, then this error occurs locally. If i run it with python3 main.py, it works as expected. I suspect my azure app service is not running the correct version of python, however, it is set to python 3.4

    StdErr:

    from newspaper import Article

UPDATE

So I went to the debug console in kudo and i ran python -m pip install --upgrade -r d:\home\site\wwwroot\requirements.txt.

Here is the error

 ERROR: b"'xslt-config' is not recognized as an internal or external command,\r\noperable program or batch file.\r\n" ** make sure the development packages of libxml2 and libxslt are installed ** Using build configuration of libxslt

One of the requirements is Pillow which requires libxml2 and libxslt. I've tried using wheels however, I've had no success.

UPDATE II I tried to install virtualenv since it does not exist and I receive a permissions error.

UPDATE III I ran this command

D:\home\python364x64>python -m pip install newspaper3k

I test everything locally, and it works perfect. I push and receive this error below.

Error occurred while reading WSGI handler:

Per my experience, we have no permission to modify D:\home environment.

So , It's better to use python extension. Please follow the steps in this case: Azure Flask Routes Not found and use command python -m pip install newspaper to install additional packages in python extension.

Please make sure the package you want to install must match with version of python extension. Otherwise, it will throw error as follows.

Hope it helps you.
