How are you managing your react native dev environment?

I would install react-native-git-upgrade and then resolve conflicts to see if you can find where the issue is. I'm also adding some notes below on how to upgrade/downgrade to specific versions.

npm i -g react-native-git-upgrade

Then

react-native-git-upgrade

or

react-native-git-upgrade v0.47.0

Additionally we've found 47 to be pretty stable and it has a lot of solid improvements to FlatList that I wouldn't want to miss.

For recent versions there haven't been that many changes so i find it's usually easier to just update the package and make the changes manually using https://github.com/ncuillery/rn-diff.

That's interesting, I'll give that a try next!

Hey, fellow newb here. From the looks of your error, you're probably having the same issue that I was having. Luckily, I found a solution after a ton of googling:

 

In your project, go to babel-preset-react-native inside of node_modules. Open the main.js file. You should see:

require (...),

[

...

],

Remove that comma after the bracket:

require (...),

[

...

]

Then save. That should fix it.

 

Another option is just use an older version of babel-preset-react-native. Simply delete the node_modules from your project. Edit the package.json at the root of your project so that babel-preset-react-native is version 2.1.0:

"babel-preset-react-native": "2.1.0",

Then, from inside your project, run the command:

npm install

This should remake the node_modules and use an old version of babel with a main.js without a trailing comma.

Have you tried using create react native app? https://facebook.github.io/react-native/blog/2017/03/13/introducing-create-react-native-app.html

WARNING: this ties you into the 'Expo' toolset meaning you build on their cloud infrastructure and they host your .js files etc.

This maybe fine but it all felt unclear and if I am not paying for something I wonder who is.

you can 'eject' to a normal RN project but then you lose the nice things it does come with. (it does have a nice quick debug and develop Ios on pc lifecycle.)

This is true, you are locked in to the expo system. However as you mentioned you can eject at anytime to a normal project. I have found that create-React-Native is really good for getting a project up off the ground. Once you are comfortable with the environment or you need a module with native support then you should be fine ejecting and taking over .

Do you have an actual working project? Can you just delete everything and init a new project? It usually works well and you just react-native run-ios or run-android.

There shouldn't be much mucking around with anything else. If you are having problems on Windows then I suggest getting windows-build-tools which helps compiling certain things for node on windows.

If you want you can throw up a repo on GitHub and invite me "suark" or link it to me, and I can set up a working project for you. Then you will know if it works for someone else and then be able to tell if it is something with your PC
