Restore path to be read from /private/etc/paths
Fix your /private/etc/paths content:

The default content is:

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin


If you want to include /usr/bin/vim (but only if vim is a folder containing some executables - the macOS installed vim exec is /usr/bin/vim!) modify the content to:

/usr/local/bin
/usr/bin/vim
/usr/bin
/bin
/usr/sbin
/sbin

You have another (superior) export PATH line somewhere (i.e. bash config files) with the following content:

export PATH="/Users/&lt;myusername&gt;/bin:/Library/Python/3.6/bin/:*"


with *= either completely missing or a falsely defined PATH variable (e.g. Path instead of PATH)

At least it doesn't inherit the standard paths defined by /private/etc/paths

This first PATH export and the second in your ~/.bash_profile then yield something broken like:

/Library/Frameworks/Python.framework/Versions/3.6/bin:/Users/&lt;myusername&gt;/bin:/Library/Python/3.6/bin/ 


as PATH
