Hi! Thanks so much for the report!

This appears to be an issue with npm5, as I'm able to start the development server via yarn. We'll try to identify a resolution soon! In the meantime, you can workaround this by installing yarn globally.

Hello! This is indeed a npm5 issue and I have reported it upstream here: npm/npm#16893

npm5 is currently buggy, I recommend you use npm4 or yarn. (the same recommendation applies for create-react-app).

Same npm5 bug as #2436

x-ref: npm/npm#16839

I have the same issue on win 7 using npm 5.0.1 Looks like there is a problem with the path -->
11:59:04: Error starting packager: Error: Couldn't start project. Please fix the errors and restart the project. at D:\xdl\src\Project.js:1039:11
I dont have such directory : D:\xdl

@mirosa06 - this is a npm bug as I mentioned above (npm/npm#16893), please use an older version of npm (preferably 4.x) or yarn

ERROR: npm 5 is not supported yet

It looks like you're using npm 5 which was recently released.

Create React Native App doesn't work with npm 5 yet, unfortunately. We
recommend using npm 4 or yarn until some bugs are resolved.

You can follow the known issues with npm 5 at:
npm/npm#16991

@sasanazizi - this is a known issue, we say explicitly in README that you cannot use npm5 with create-react-native-app. I don't recommend using npm5 at all right now (as of writing, latest version is 5.0.3) because it is too buggy

@13hoop - yarn works but you need to re-create the project or delete node_modules and run yarn install again. the problem with npm5 is that it installs the dependencies incorrectly when you create the project.

[aswerdlow935]

Is there an easy way to downgrade from npm 5.0.3 to 4 that works with react native?

[brentvatne]

@aswerdlow935 - npm i -g npm@4.6.1 - then install create-react-native-app again and create a project as per readme intructions
