'"npm run build" = "react-scripts: Permission denied"
I'm trying to deploy my working Windows 10 Spring-Boot/React app on Ubuntu 18.04 but keep getting "react-scripts: Permission denied" error despite numerous attempts to fix. Hopefully one of you react experts can spot what I'm doing wrong.
My package.json looks like this
{
"name": "medaverter-front",
"version": "0.1.0",
"private": true,
"dependencies": {
"@testing-library/jest-dom": "^4.2.4",

"react-table-6": "^6.11.0",
"react-validation": "^3.0.7",
"reactstrap": "^6.5.0",
"validator": "^12.2.0"
},
"scripts": {

"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"
]
}
}
I'm logged in as root and used nvm to install node and lts. I installed nvm like this:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash
then did this:
nvm install node
nvm use node
nvm install --lts
nvm use --lts
Then I cd
to /var/lib/jenkins/workspace/MedAverter/medaverter-front
and install node_modules
like this:
npm install -g
and then change the permissions to 777 recursively, like this:
chmod -R 777 node_modules
I also changed all the /root/.nvm permissions to 777 recursively, like this:
chmod -R 777 /root/.nvm
I can get it build once using
npm run build
but then I run a "Build Now" from Jenkins and it fails with the same
[[1;34mINFO[m] Running 'npm run build' in /var/lib/jenkins/workspace/MedAverter/medaverter-front [[1;34mINFO[m] [[1;34mINFO[m] > [email protected] build /var/lib/jenkins/workspace/MedAverter/medaverter-front [[1;34mINFO[m] > react-scripts build [[1;34mINFO[m] [[1;31mERROR[m] sh: 1: **react-scripts: Permission denied** [[1;31mERROR[m] npm ERR! code ELIFECYCLE [[1;31mERROR[m] npm ERR! errno 126 [[1;31mERROR[m] npm ERR! [email protected] build: `react-scripts build` [[1;31mERROR[m] npm ERR! Exit status 126
Then I cd
to /var/lib/jenkins/workspace/MedAverter/medaverter-front
and run
npm run build
And also get the same error again:
> root@ubuntu-s-1vcpu-1gb-nyc1-01:/var/lib/jenkins/workspace/MedAverter/medaverter-front# > npm run build > > > [email protected] build /var/lib/jenkins/workspace/MedAverter/medaverter-front > > react-scripts build > > sh: 1: **react-scripts: Permission denied** npm ERR! code ELIFECYCLE > npm ERR! errno 126 npm ERR! [email protected] build: > `react-scripts build` npm ERR! Exit status 126
I've literally spent days trying to figure this out. Suggestions?

I finally figured out a solution to this problem. It took days of effort. First, I deleted the Jenkins project and created a new one using Pipeline, rather than Freestyle. Then I added a Jenkinsfile with a script. That continued to fail but now I had the flexibility to add in additional commands to handle the errors.
One new error was something about jest-worker. I ran the following command on the DigitalOcean server to get past that one:
yarn add jest-worker
Then I had the old permissions error again. I think all these permission errors are due to user jenkins trying to run things owned by user root, even though everything had 777 permissions. I don't understand that but here's how I got around it. Modify the /etc/sudoers file and add the following line:
jenkins ALL=(ALL) NOPASSWD:ALL
Then modify the Jenkins file script to include recursive chmod and chown. Here is the full script that FINALLY worked:
pipeline {
agent any
stages {
stage('Checkout') {
steps {
echo 'Checkout...'
sh 'sudo chmod -R 777 /var/lib/jenkins/workspace/MedAverter/medaverter-front'
checkout scm
sh 'sudo chmod -R 777 /var/lib/jenkins/workspace/MedAverter/medaverter-front'
sh 'sudo chown -R jenkins /var/lib/jenkins/workspace/MedAverter/medaverter-front'
stash 'sources'
}
}
stage('Build') {
steps {
echo 'Build...'
unstash 'sources'
sh 'sudo chmod -R 777 /var/lib/jenkins/workspace/MedAverter/medaverter-front'
sh 'sudo chown -R jenkins /var/lib/jenkins/workspace/MedAverter/medaverter-front'
sh 'mvn clean package -DskipTests'
stash 'sources'
}
}
}
}
I also had to increase the memory of the DigitalOcean droplet from 1GB to 2GB to get past another error. If someone knows a better way to get past that frustrating permissions error, please comment.

Solution 1:
I think you have react-script globally installed. so try this command
npm install react-scripts --save
and then run the application again.
Solution 2:
try this command
sudo chmod +x node_modules/.bin/react-scripts
and then run the application again.
Solution 3;
I think your npm not have permission. you can try to run by sudo
sudo npm run build
and you can fix this problem like this
Step 1:
check path of npm if you are using npm by
which npm
you will "/usr/local/bin/npm" this type of path
OR
check path of yarn if you are using yarn by
which yarn
you will "/usr/local/bin/npm" this type of path
Step 2:
give permission 777 to this path and try to run project
sudo chmod -R 777 /usr/local/bin/npm

Solution for macOS
From the root of your project run:
chmod +x node_modules/.bin/react-scripts
Solution 4:[4]
Instead of the default "start": "react-scripts start"
specified in your package.json
file, try changing it to the following and then try: "scripts": { "start": "node ./node_modules/react-scripts/bin/react-scripts.js start" }

I had modified the permissions on the folders earlier and undid the changes. I believe that is it.
I just deleted the node_modules
folder and reinstalled the dependencies with the yarn
command.
sudo rm -rf node_modules
yarn
yarn start

It seems you don't have the right permission to build or execute the react app,
What you could do is try changing the owner to the current user using
sudo chown -R username:username /var/lib/jenkins/workspace/MedAverter/medaverter-front/
you can check your username by typing whoami
in the terminal this is done because the current user does not have access to to the var
folder or anything inside it by default. Furthermore you want to change the access mode to read and execute for everyone using
sudo chmod 755 /var/lib/jenkins/workspace/MedAverter/medaverter-front/
then you can want to change to root user using
sudo su
and then build the app using
npm run build
This has worked for me when i was facing somewhat a similar problem , hopefully it works for you as well,Cheers :)

That happens because of lack of a package.json file Just run this command and the issue will be fixed:
npm audit fix
Solution 8:[8]
In my case it was giving at npm run. this is how i solved.
- rm -rf /node_modules
- npm i
- npm run android
Solution 9:[9]
Sometimes npm need root permission. Try using sudo in the command. It resolved a similar issue for me. This might help.
sudo npm run build
