sudo: command not found

Question

Every time I try to use a sudo or ssh command, it returns with this error:

when:~ jackson1442$ sudo [insert any command here]
-bash: sudo: command not found

I was messing with Python installs, and am not sure what I did to cause this. How can I permanently fix this?

macOS Sierra 10.12.4 16E195
MacBook Pro 2016
13" Touchbar

EDIT: here's the path:

when:~ jackson1442$ echo $PATH
’/usr/local/bin:??

Here is .bash_profile

# Setting PATH for Python 2.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH

# Setting PATH for Python 3.5
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.5/bin:${PATH}"
export PATH
export PATH=’/usr/local/bin:��

Answer 1

Your PATH is hosed!

First check your .bash_profile file with:

/usr/bin/nano ~/.bash_profile

Prepend lines containing something like export PATH="/... " with a # to comment them out. Save the file with ctrlO and exit nano with ctrlX

Then check /etc/paths with: /bin/cat /etc/paths.

It should look like this:

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

You can edit the file with /usr/bin/sudo /usr/bin/nano /etc/paths if required.

If everything is fine enter source ~/.bash_profile or close the Terminal window and open a new one.

Now sudo should work again. Then check all #export PATH=... lines in your .bash_profile for potential errors. You may add them to your question to get help here.
