I am new to React.js. And I followed the tutorials in https://github.com/facebook/create-react-app. It worked fine while running npm init react-app my-app. But I got error when I run npm start.
detailed error message:
I have tried https://stackoverflow.com/questions/39959900/npm-start-error-with-create-react-app. That dose not work for me. I also tried move my project folder to upper directory, which still doesn't work.....
Can anyone fix it?
add: package.json
{
"name": "my-app",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^16.5.2",
"react-dom": "^16.5.2",
"react-scripts": "2.0.5"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"eslintConfig": {
"extends": "react-app"
},
"browserslist": [
">0.2%",
"not dead",
"not ie <= 11",
"not op_mini all"
]
}
try npm install -g

Found the solution my self! :)
I had to run npm run build to create the build folder. Then ran npm run deploy
I tried to update my version of create-react-app by doing this:
If you've previously installed create-react-app globally via npm
install -g create-react-app, we recommend you uninstall the package
using npm uninstall -g create-react-app to ensure that npx always uses
the latest version.
But now, when I run npm start, i get an error message:
missing script: start
But in the package.json from my app, i found the start script:
{
"name": "dropzone-montessori",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^16.12.0",
"react-dom": "^16.12.0",
"react-scripts": "3.2.0"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"eslintConfig": {

"not dead",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}
Anybody knows what's happening?
I try to deploy my react web app to github pages but when i can't find website online
In the console, it says that the app is ready to publish and i should run command npm run deploy but i see the same message every time i run that command
Here's package.json file:
{
"name": "weather-app",
"version": "0.1.0",
"private": true,
"homepage": "http://shotiko-forecast.github.io/weather",
"dependencies": {
"react": "^16.12.0",
"react-dom": "^16.12.0",
"react-redux": "^7.1.3",
"react-scripts": "1.1.4",
"redux": "^4.0.4",
"redux-thunk": "^2.3.0"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject",
"predeploy": "npm run build",
"deploy": "gh-pages -d build"
},
"eslintConfig": {
"extends": "react-app"
},
"browserslist": {
"production": [
">0.2%",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}
install dependencies to the project.
> npm i gh-pages
In your package.json add script and homepage
"homepage": "https://username.github.io/repo-name",
"scripts": {
"deploy": "gh-pages -d build"
}
run build Script to build for production
npm run build
run deploy script to deploy your code to the-pages it automatically push on git-hub gh-pages branch and auto-selected on gh-pages branch you can check settings > GitHub pages.
npm run deploy
now it time to check your
https://username.github.io/repo-name
The name of your React app is weather-app. I assume that the github repository for the app is named as weather-app. There is an error in your package.json file. The homepage property is set incorrectly.
It should be set as,
"homepage": "http://<<github-user-name>>.github.io/<<github-repo-name>>"
In your case, change weather to weather-app and everything should work fine
I had created a new react project and while running it using npm start it shows me ELIFECYCLE error.
I had tried deleting the package.lock.json and node_modules and removed the dependencies and done a fresh npm install. Eventhough the same error occurs again.
This is my package.json file:
{
"name": "tables",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^16.9.0",
"react-dom": "^16.9.0",
"react-scripts": "3.1.1"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"eslintConfig": {
"extends": "react-app"
},
"browserslist": {
"production": [
">0.2%",
"not dead",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}
C:\Users\Srinithi K\tables
this is my path where the react project called tables is present.
output after running npm start:
This might be due to package-lock.json file. If you had not run eject, it might not have occurred. Installing the latest version of npm would help.
Try these fixes:
Go to your application directory in the command prompt,
rm -rf node-modules
npm install npm#latest -g
npm install
You might consider the following command if the above fix doesn't work.
npm install react-scripts
I followed all the steps for deploying my React App , but it deploys a New React App on Github and My Components and My Code is not there .
I added "homepage" and "predeploy" , "deploy" in my Package.json file but when those files got on github , it disappeared .
Here is link to Github repository : https://github.com/cyumair/smartbrainapp
//This is my Package.json

your .gitignore file currently ignores the build folder. that's why your files did not get pushed onto your github repo.
# production
# /build <= comment out this line
The Problem Is Solved By Changing # production
# /build
to # build / in .gitignore file
and changing "homepage" : "" in package.json file.
And then Running Following Commands In Console :
$git add .
$git status (This showed that my missing files were new and needed commit )
$git commit -m "adding the missing files "
$git push -u origin master
$npm run deploy
I Deleted The Old Repository And Applied The Same Steps on New One , You Can See Working React App at: https://cyumair.github.io/smartbrain/
//package.json file
"homepage":"https://github.com/cyumair/smartbrainapp"
//Changed To
"homepage":"https://cyumair.github.io/smartbrainapp"
