I have installed react-native and built some simple application. I ran it and everything was fine. After a while, I could not run anymore my application, because every time I type "react-native start" in cmd, it gets me something like in the picture below. Does anyone have any idea?
EDIT: package json looks like:
{
"name": "AwesomeProject",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest"
},
"dependencies": {
"react": "15.3.2",
"react-native": "0.36.0",
"react-native-checkbox": "^1.0.15",
"react-native-mail": "^2.0.0"
},
"jest": {
"preset": "jest-react-native"
},
"devDependencies": {
"babel-jest": "16.0.0",

"jest": "16.0.2",
"jest-react-native": "16.0.0",
"react-test-renderer": "15.3.2"
}
}
according to me you need to run npm install from your root project dir because you might have deleted some file from node_module folder which will be recovered after running the above command.

I'm having some issues with a CRUD desktop application I developed with the help of a freelancer. It's an electron-forge build that works seamlessly on Windows 10, and works on MacOS initially when accessing the out folder, the strange thing happens when:
I use npm run publish to zip the Mac/Darwin instance
I manually package.zip the results of npm run make
When I do this, and unzip the file to run, the SQLite integration fails completely. The app appears to be working upon start, but no changes can be made to the DB objects, nor can new objects be made.
The freelancer who put together the DB integration said he was not able to solve this issue, but it's impossible to put apps in marketplaces without zipping the application for delivery. I can post code if necessary, I just don't even know what aspect of the code would be relevant, and feel like there has to be something I can install/put in my package.json that might solve this, but I'm just not sure.
Here is my package.json file in case that is helpful:

I found that by simply creating a DMG target (see https://www.electronforge.io/config/makers/dmg) that I did not need to worry about unzipping process. I believe DMG is the ideal approach for packaging Mac OS apps that have something like a SQLite database integration within.
First off, I'm new to react-native so please excuse my missing knowledge regarding troubleshooting.
I have built a basic app using Expo, which runs perfectly fine when I run expo start and scan the QR code to run it on my physical device.
I then ran expo build:android in my terminal and selected apk to create an apk file. It installs, but when I try to open the app on my phone, it crashes straight away. I'm not sure why this happens, or how to troubleshoot it.
Some steps I have taken:
Reinstalled expo-cli
Reinstalled react-native
Ran npm-update
Manually downgraded my sdkVersion to 37.0.0 in my app.json file (as suggested by online forums)
Here is my app.json file:
{
"expo": {
"name": "FactApp",
"slug": "FactApp",

And here is my package.json file:

Any help would be greatly appreciated!
So I created a fresh new app with expo-cli and the resulting APK crashed so I figure it's an issue with expo. I used react-native cli to create an apk for this app and it works with no issues
I was running an Electron project, and everything worked just fine. But now when I run any of the scripts in my package.json (including npm start), it just escapes a line and doesn't do anything.

I tried updating NPM, didn't work. When I tried in different projects, also doesn't work.
Thanks in advance
npm has a ignore-scripts configuration key. It's expected value is a Boolean and it's set to false by default.
Perhaps it has inadvertently been set to true.
To get/set the ignore-scripts configuration you can utilize the npm-config command:
Check its current setting by running:
npm config get ignore-scripts
If the aforementioned command returns true then reset it to false by running:
npm config set ignore-scripts false
If you are using an integrated terminal (such as the VsCode integrated terminal) try running your npm "run dev' command from your PowerShell (or cmd) terminal. This error arises as a result of your integrated terminal not recognizing your command (especially if you created your app with a git bash terminal).
Try this, and I hope it helps someone cause it always works for me. Cheers!!!
I have spent over a day trying to get map view to work and along the way I picked up this error that I can't find anywhere at all on the internet. The error code shows up on iOS simulator with a red screen as is typical for react native.
I tried reinstalling the Dev Tools and that didn't work.

please help
I found out an answer that works for me, but I'm not sure. Maybe this can help people in the future. I ran:
"yarn add eslint-config-rallycoding --dev"
"npm start"
(in project directory)
Got this issue after ejecting from Expo (with ExpoKit). Had a working environment before ejecting. npm run ios will run with this issue repeating over and over:

As #SyedZainAli mentioned this might be caused by environment. A few things to try then is:
Remove node_modules, run npm cache clean and reinstall
Reinstall NodeJS
Create a new app using CRNA and compare
In my case ejecting and using Expo react-native branch (default behavior) causes the issue. Changing back to official react-native npm package resolves the issue. So should be something on Expo's side.
I don't know if this may help you, but it fixed my issue within docker.
In Docker file
//////////////////////////////////////////////////////////////////////////

Needed libc6-compact
so try installing libc6-compat.
I had the same issue (below) when I was trying the start an app I got from my team in Expo. And it turned out that uws version in the project was not compatible with the Node version I was using. - node v10.15.0
Switching the node version to be 8.11.4 using nvm - nvm use 8.11.4 solved my issue. (If there is no 8.11.4 version installed use nvm install 8.11.4 instead)
