If anyone coming here because of getting this error while running a google app engine Python 3.7 standard environment project in PyCharm then all you need to do is

Make sure the configuration to run is for Flask, not Google App Engine configuration.
Then disable Google App Engine support under Preferences >> Languages & Framework >> Google App Engine

The reason being as per this link

The overall goal is that your app should be fully portable and run in any standard Python environment. You write a standard Python app, not an App Engine Python app. As part of this shift, you are no longer required to use proprietary App Engine APIs and services for your app's core functionality. At this time, App Engine APIs are not available in the Python 3.7 runtime.

I guess when we create a python 3.7 project in PyCharm as a Google app engine project it still tries to do the same way it does for a python2.7 app

In case you have to keep PYTHONPATH for both python2 and python3  you can write alias statements to set the proper PYTHONPATH in your bash profile   Hardcode your PYTHONPATH2  and PYTHONPATH3 variables in your    bash profile  and add the following aliases at the end of it   alias python  export PYTHONPATH   PYTHONPATH2  python  alias python3  export PYTHONPATH   PYTHONPATH3  python3    My python  refers to python2  as I use python2 more often

I have Python 2 and Python 3 installed on my computer  For some strange reason I have in the sys path of Python 3 also a path to the sitepackage library directory of Python2 when the re module is called  If I run Python 3 and import enum and print enum   file    the system does not show this Python 2 path to site-packages  So a very rough and dirty hack is  to directly modify the module in which enum is imported  follow the traceback paths  and insert the following code just before importing enum   import sys for i  p in enumerate sys path       if  python27  in p lower   or  python2 7  in p lower    sys path pop i  import enum   That solved my problem

DISCLAIMER  Please   juanpa arrivillaga  if you see this answer  feel free to write your own and I will remove this post    juanpa arrivillaga had mentioned above      Is there a file name enum py in your working directory  by any chance    This was the issue I encountered  I was not aware of the enum module on python at the time and had named my test file enum py   Since the file name is the module name  there was a conflict  More info on modules here  https   docs python org 2 tutorial modules html

Installing version 1 1 8 of enum34 worked for me      I was able to fix this by adding enum34      1 1 8  to pyproject toml    Apparently enum34 had a feature in v1 1 8 that avoided this error  but   this regressed in v1 1 9   This is just a workaround though  The   better solution would be for packages to use environment markers so   you don t have to install enum34 at all unless needed    Source  https   github com python-poetry poetry issues 1122

It s because your enum is not the standard library enum module  You probably have the package enum34 installed    One way check if this is the case is to inspect the property enum   file    import enum print enum   file        standard library location should be something like     usr local lib python3 6 enum py   Since python 3 6 the enum34 library is no longer compatible with the standard library  The library is also unnecessary  so you can simply uninstall it   pip uninstall -y enum34   If you need the code to run on python versions both  lt  3 4 and  3 4  you can try having enum-compat as a requirement  It only installs enum34 for older versions of python without the standard library enum

I did by using pip install  lt required-library gt  --ignore-installed enum34 Once your required library is installed  look for warnings during the build  I got an Error like this  Using legacy setup py install for future  since package  wheel  is not installed ERROR  pyejabberd 0 2 11 has requirement enum34  1 1 2  but you ll have enum34 1 1 10 which is incompatible  To fix this issue now run the command  pip freeze   grep enum34  This will give you the version of the installed enum34  Now uninstall it by pip uninstall enum34 and reinstall the required version as  pip install  quot enum34  1 1 20 quot

I got this issue while installing transformers library from HuggingFace  It was due to the fact package enum34 was installed in my environment which was overriding built-in enum in Python  This package was probably installed by something as for forward compatibility which is no longer needed with Python 3 6   So the solution is simply  pip uninstall -y enum34
