ngrok command not found [closed]

Question

Short answer: Put the executable file in /usr/local/bin instead of applications. You should now be able to run commands like ngrok http 80.

Long answer: When you type commands like ngrok in the terminal, Macs (and other Unix OSs) look for these programs in the folders specified in your PATH. The PATH is a list of folders that's specified by each user. To check your path, open the terminal and type: echo $PATH.

You'll see output that looks something like: /usr/local/bin:/usr/bin:/bin. This is a : separated list of folders.

So when you type ngrok in the terminal, your Mac will look for this executable in the following folders: /usr/local/bin, /usr/bin/ and /bin.

With Homebrew already installed on your Mac, you can easily install ngrok from the terminal, using this command:

$ brew cask install ngrok

Then run it from the shell using this command:

$ ngrok http 8000

With this command, you're telling ngrok to basically create a tunnel to your localhost 8000 and assign an internet name host for it. And thats it. You should be good to go.

• Download the zip file.
• Unzip it.
• Open The terminal in the current location (inside unzip folder) where you unzip the file.

• Execute the following command into the terminal :

  sudo cp ngrok /usr/local/bin          
  

  Now your ngrok execuatable file is successfully copied to the /usr/local/bin directory. Now you are able to run the ngrok command in the terminal

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.

This is how I got it to work..

For Mac

1. If you downloaded via a download link, you need to add ngrok path to your .bash_profile or .bashrc whichever one you are using.

For Windows 10 bash:

1. Download ngrok from https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-windows-amd64.zip
2. Move executable file ngrok.exe to C:\Windows\system32\ngrok.exe
3. Add Environment Variables via UI (search for "Edit the environment variables for your account" in the search bar next to windows logo => double click on Path under Users Variables for yourusername => Click New => add your path C:\Windows\system32\ngrok.exe => click OK.
4. Restart your bash and you should be able to run "ngrok http 80" command.
