I\'m trying to install ngrok
(which I\'ve been using for a while on Windows with no issues) on my 1 week old yosemite and these are the steps I\'ve followed so
I have also faced this issue on my MacOS, I used these simple steps and it worked for me.
Just open the terminal and go to your project folder where you what to start ngrok and then unzip downloaded file.
$ unzip /path/to/ngrok.zip
After doing this you don't need to authenticate ngrok, just run this command:
./ngrok http 80
It should work now.
