I can reset OS X PATH with this method

In configuring your system’s PATH in OS X (ex. .bash_profile or direct method), whether for PhoneGap/Cordova, or Android application development, you can make a mistake like me.

Those mistakes might cause OS X unable to use any command.

Here is how I resolved the problem by reset OS X path.

Let’s reset our OS X’s PATH

Open your terminal, then execute following command:

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

That should fix it. 🙂
