'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.

Answer 1

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.

1. Hit Windows key and search for Environment variables.
2. 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)

3. Open a new command prompt and enter

> expo

You will see something like this:

Answer 2

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

1. 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.

2. Use yarn to install expo with yarn global add expo-cli.

3. expo start should work now. yarn start and npm start should also work.

Hope that helps!
