Flask PermissionError:[Errno 13]权限被拒绝 [英] Flask PermissionError: [Errno 13] Permission denied

问题描述

我正在尝试使用/opt/mount1/python35/bin/python3.5 notification.py 运行Flask应用程序，但出现以下错误:

I am trying to run a Flask application using /opt/mount1/python35/bin/python3.5 notification.py and I am getting the following error:

WARNING:tensorflow:From /opt/mount1/python35/lib/python3.5/site-packages/tensorflow/python/framework/op_def_library.py:263: colocate_with (from tensorflow.python.framework.ops) is deprecated and will be removed in a future version.

我已对flask应用程序文件夹授予了递归777权限.

I have given recursive 777 permission to the flask application folder.

从上面的堆栈跟踪中，我不确定出了什么问题.

From the above stack trace, I am not sure what is going wrong.

任何帮助将不胜感激.谢谢！

Any help will be appreciated. Thanks!

我试图使用CentOS 7.6的核心python(即python 2.7 )运行Flask应用，并且有效！

I tried to run the Flask app using the core python of CentOS 7.6 i.e Python 2.7 and it worked!!

我不确定为什么不适用于从其RPM安装到路径/opt/mount1/python35 的python 3.5.6 版本.

I am not sure why it is not working for a python version 3.5.6 which has been installed from its RPM to the path /opt/mount1/python35.

推荐答案

由于我已经在不同的路径中分别安装了Python 3.5，因此必须在文件顶部放置以下 shebang 解决此问题:

Since I had installed the Python 3.5 separately in a different path, I had to place the following shebang at the top of my file to fix the issue:

#!/opt/mount1/python35/bin/python3.5
