'expo' is not recognized as an internal or external command

Question

After running npm install -g expo-cli and successfully installing the packages globally, expo is still not recognized as an internal or external command. Does anyone know how I might get around this issue using windows 10, or what to do in terms of something like a path variable.

if installed using YARN add `C:\Users\{USER}\AppData\Local\Yarn\bin` to path — Qwerty, Jul 13 '21 at 14:00

Probably the only thing missing is to add the expo executable to your path.

For Windows 10, you can simply add the npm folder to your path environment variable.

Hit Windows key and search for Environment variables.
Inside the Path variable under System variables, add a new entry (entries are separated by semicolons) with this content (without /node_modules ):

%USERPROFILE%\AppData\Roaming\npm

OR if you are using yarn C:\Users\{USER}\AppData\Local\Yarn\bin (as @Qwerty mentioned above)

Open a new command prompt and enter

> expo

You will see something like this:

This answer fixed my problem, but why the key "%USERPROFILE%\AppData\Roaming\npm" deleted after a period of from Path variables – hamzeh.hanandeh Aug 30 '20 at 18:12
If you already have path variable you can add the above by typing a semicolon – Gayatri Dipali Dec 31 '20 at 12:21

I wondered it was working last night when I first installed and run the "react-native" project but the very next day it showed me the same error as yours.

Here is what I did in windows 10 Operating System:

Add the following path :

environment variable > System Variables > PATH > C:\Users\YOUR_USERNAME\AppData\Roaming\npm

Now I ran the following commands one by one in CMD:

i) npm -g uninstall expo-cli --save

ii) npm install -g expo-cli

Now start the Project and run npm start and now it works for me.

I didn't try this article one but it also shows the solution for the same problem, see here

I may be too late to answer this, but for people looking for the same error this is what worked for me.

Install yarn if you don't have it. I used the command choco install yarn (you'll have to install Chocolatey). If you have scoop installed, scoop install yarn also works.
Use yarn to install expo with yarn global add expo-cli.
expo start should work now. yarn start and npm start should also work.

Hope that helps!

I have the same error and although this I haven't figured out how to solve it – Gianmarco Nov 13 '19 at 10:16
It might be the solution. But, setting environment variable can solve the issue so there's no need to add another package. No offence but as an efficient solution, I would consider is setting *environment variable* instead of installing `yarn` – meDeepakJain Jan 13 '20 at 11:28

go to the environment variable, then in the user variable section find Path and press the edit button, you will see a new window, press new and add the following

%USERPROFILE%\AppData\Roaming\npm

then press ok. Now,

expo --version

Here is the solution I came out with.

I ran npm list -g

then copy the directory on the first line and paste in your system enviroment variables under the variable name 'path'

close all the terminals and run expo or any other command.

If it still doesnt work or you can't access npm. Try setting the path with the Windows PowerShell:

Open Windows Powershell as Administrator
Type: setx path "%path%;C:\Users\USERNAME\AppData\Roaming\npm"

It worked for me.

After installing nodejs reboot your computer

Generate a new project with - npx expo-cli init projectName
cd projectName
npm start

If you are using Windows 10 or 11, the solution to edit your Path variable works well. Just make sure that you replace "YOUR_USERNAME" with your username on the computer:

This means that if my username is "Green", I will replace YOUR_USERNAME here: C:\Users\YOUR_USERNAME\AppData\Roaming\npm

to

C:\Users\Green\AppData\Roaming\npm.

This article is very detailed in solving the problem in case if the above does not work for you.

This worked for me:

You must uninstall node js then install it again.
You must run npm install expo-cli.

It will solve your problem

If you are using yarn global add expo-cli, try npm install -g expo-cli.

I don't know why but when i go into C:\Users\%{user}%\AppData\Roaming\npm there isn't the expo package(and other packages that I thought I install globally by yarn) but there are other that I installed globally by npm.

If adding C:\Users\%{user}%\AppData\Roaming\npm to PATH variable doesn't work, give this a shot.

I had the same problem last night, and I've recently started my journey in ReactNative. So, there might be better answers out there.

If you're following the ReactNative Official documentation, the first time npm start works fine, the subsequent ones throws an error saying expo is not recognized. I got around that by running expo start and not npm start ( which basically is the same thing but doesn't work for some reason ).

So, mine looks like a work around rather than an explanation as to why this happens or how to permanently fix it.

If expo is not recognized, how i run "expo start"??? – Samir Diaz Jun 01 '23 at 16:41 — Samir Diaz, Jun 01 '23 at 16:41

This is a more general problem where your global node modules are not in your system path. This question is what you are looking for: Nodejs cannot find installed module on Windows?

I faced same problem and it was not getting resolved by "npm install --global expo-cli". Global CLI was having error as SS below -

npm list -g --depth 0

Followed below steps to get it resolved

npm uninstall --global expo-cli
Deleted global package causing error C:\Users<USERNAME>\AppData\Roaming\npm\node_modules\expo-cli
npm install --global expo-cli

And expo cli worked. Happy coding!!!

If you need a solution to Run Expo command without Environment Variable update then on your terminal use below command for windows system:

R:\> C:\Users\{user}\AppData\Roaming\npm\expo.cmd init {projectname}

Where you directly point the expo.cmd file rather than specifying in the environment variable.

And update the expo to C:\Users{user}\AppData\Roaming\npm\expo.cmd in package.json to run the project.

// package.json
"scripts": {
    "start": "C:\\Users\\{user}\\AppData\\Roaming\\npm\\expo.cmd start",
    "android": "C:\\Users\\{user}\\AppData\\Roaming\\npm\\expo.cmd start --android",
    "ios": "C:\\Users\\{user}\\AppData\\Roaming\\npm\\expo.cmd start --ios",
    "web": "C:\\Users\\{user}\\AppData\\Roaming\\npm\\expo.cmdstart --web",
    "eject": "C:\\Users\\{user}\\AppData\\Roaming\\npm\\expo.cmd eject"
  },

Could you revise the answer more clearly using code blocks? – myeongkil kim Dec 21 '20 at 06:44 — myeongkil kim, Dec 21 '20 at 06:44

If you set the environment path as said in other replies and the command is still not recognized, try running whatever you're using to execute the command in administrator mode.

I'm using VS Code terminal and expo was not recognized until I ran it as administartor.

'expo' is not recognized as an internal or external command
