Python3.7: error while loading shared libraries: libpython3.7m.so.1.0

You need to add /usr/local/lib/ to the library search path. You can call the following in the current shell before running python3.7:

export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib

Or run ldconfig to add the path to the linker cache:

sudo ldconfig /usr/local/lib
