I have created a new app with npx react-native init. The installation is completed and I can run my app with npx, but it's giving me this error during installation:
⠋ Downloading templateerror Cannot parse yarn version: 0.32
⠴ Downloading templateerror Cannot parse yarn version: 0.32
✔ Downloading template

⠋ Installing dependencieserror Cannot parse yarn version: 0.32

Similarly, if I run any yarn command like yarn start, it doesn't recognize it:
00h00m00s 0/0: : ERROR: [Errno 2] No such file or directory: 'start'
Writting yarn --version returns 0.32.
Yarn may be missing. Try installing it via npm:
sudo npm install yarn -g

then changing to the ios folder and issuing "pod install" yields:

Reinstalled Node using NVM
Apparently the node I installed multiple times through the store was giving the error so I decided to use the Node Version Manager instead.
Instructions:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

If you previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:
Run this command

but CocoaPods is installed:

react-native version is 8.0.6
If you are using M1 or up processor, try updating ruby and again install cocoapods or you can go into iOS folder and do pod install
I possible please share whole error from terminal.
Thanks :)
first time using react native. When i run npm start and open the localhost, it says "An unexpected error has ocurred". If i scan the QR code in the Expo app, it says "Something went wrong. Network responde timed out".
When i open the console this appears
I created the app as:
npm install -g expo-cli
expo init MyApp
Selected the typescript template
And then at the MyApp folder npm start
Its probably because of new version of expo-cli#5.4.10
Uninstall new version and install 5.4.7
For npm:
npm -g uninstall expo-cli
npm -g install expo-cli#5.4.7
For yarn:
yarn global remove expo-cli
yarn global add expo-cli#5.4.7
I'm trying to build a project in expo react native project.
My expo version is 3.2.2, sdkVersion is 35.
When I ran in cmd (on Windows 10)
set EXPO_DEBUG=true
expo build:android -c
I got:
Request failed with status code 400

I'm tried to update expo version, sdkVersion, the version in react, check for internet connection.
Expo login and logout works fine. I don't have any proxy in my network.
I don't have any clues for what search or how to fix this problem.
Seems was a error in expo-cli version 3.2.2.
The update 3.2.3 fixed for me.
I have fixed the issue by using this command
Move to your root folder then type this command in your terminal
npm install -g expo-cli
I had two versions of expo-cli installed (one via yarn global install expo-cli and one as a dev dependency in project yarn add -D expo-cli). This started working for me after I removed the global expo-cli:
yarn global remove expo-cli
and used the local version in my project instead:
yarn run expo-cli start
Run those following command, then we are good to go.
$ yarn global remove expo-cli && yarn global add expo-cli
$ rm -rf node_modules/ yarn.lock && yarn install
$ yarn run start
