Install the libstdc++ package since it says there’s no such file or directory

Or create a requirements.txt with Shapely==1.7.1 in it to see if it resolve the libstdc++.so.6 errors

NO use :
requirements.txt with Shapely==1.7.1

Please tell me how to Install the libstdc++ package

you can try setting the LD_LIBRARY_PATH environment variable to include the directory where the libstdc++.so.6 library is located. Assuming the library is in the /usr/lib directory

export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH
this command would do that, (had to look it up)
