MacOS – The terminal on the Mac does not work anymore after installing Python & Sublime Text

bashmacospythonterminal

I was trying to install Python3, and Sublime Text 3 in order to learn and run Python. Unfortunately, I watched some videos on youtube and tried to follow their instructions, I did something with my Terminal and now it does not work at all. Please explain and show me how to fix it!

In Terminal it shows:

Lances-MacBook-Pro:~ lancedang$ touch
-bash: touch: command not found
Lances-MacBook-Pro:~ lancedang$ python
-bash: python: command not found
Lances-MacBook-Pro:~ lancedang$ python3
-bash: python3: command not found

Your PATH environment variable seems to have been changed somewhere.

Type the following command at your Terminal prompt:

echo 'PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:~/bin:$PATH' >> ~/.bash_profile

Exit terminal and the shell by typing exit and closing the Terminal app. Relaunch.

Everything should be working now.

Well, wget isn't installed by default on Mavericks. You could install it through homebrew though.

If you installed wget yourself at one time then you may just need to adjust your $PATH to find it again.

PATH=/path/to/wget:"${PATH}"

Take a look in /bin and /usr/bin to see what tools are installed and try one of them to see if Bash is working correctly.

First, get your PATH back for the current shell by running

PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"
export PATH

Then fix the PATH problems

edit your bash-profile and put back the line you've deleted. If you don't remember, take the two lines from above
path_helper takes its input from the files in /etc/paths.d, at least one of those files seems to be corrupt (the last two entries in the output look kind of strange). To fix, run /bin/ls -l /etc/paths.d to get the name of the file containing the additions for omnet++ (should be named accordingly) and remove it with sudo /bin/rm /etc/paths.d/NAME-OF-FILE
