I want to make command python3 to run python3.7

Question

I am currently using Mac OS Mojave version 10.14.2 I just installed python3.7 and uninstalled python3.6. Then, the following result occurs

$ python3
-bash: /Library/Frameworks/Python.framework/Versions/3.6/bin/python3: No such file or directory
$ which python3
-bash: type: python3: not found
$ which python3.7
python3.7 is /usr/local/bin/python3.7

I want to make the python3 command runs python3.7 but I am very confused of the setting of python. I searched on Google but I couldn't solve it. Could you please help me? Thank you

perhaps not the ideal solution but an easy work around is creating an alias in your bashrc. alias python3='python3.7' — jonroethke

It is not a good idea to replace the system installed Python interpreter as some OS functions depend on that specific release. It is better to keep both versions. — Selcuk

That's a bad soft link since you removed python3.

Check out where python3 is by

which python3

Then use the return of that output to see what it's currently pointing to

ls -la $(which python3)

Replace the bad python3 softlink with the correct python3.7

ln -sf $(which python3.7) /usr/local/bin/python3

Test out the version

python3 --version

In the future, check out pyenv because it will make installing new versions of python and switching between versions much easier.
