Treating warnings as errors because process.env.CI = true. Failed to compile
Solution 1
"scripts": {
"start": "react-scripts start",
"build": "CI=false && react-scripts build", // Add CI=False here
"test": "react-scripts test",
"eject": "react-scripts eject"
},
Solution 2
For me the solution was:
env:
CI: false
Solution 3
For me replacing npm run build
with CI='' npm run build
worked.
Solution 4
In my specific case, I was using Netlify, so all I did was set the ENV vars inside Netlify's panel:
- Select Site Settings Tab
- Select Build and Deploy
- Scroll down to Environment variables and press Edit Variables
- Fill it in with Key = CI and Value = false
- Press save and trigger a new deploy
Solution 5
if you have to continue with the build and deploy from within GitLab CICD pipelines, you can include CI=false like so:
CI=false npm run build
or
unset CI
npm run build
Here is a complete gitlab_ci job sample:
build-dev:
environment: DEV
image: node:16
stage: build
script:
- npm install
- CI=false npm run build
only:
- /^devrelease-.*$/
tags:
- docker
or
build-dev:
environment: DEV
image: node:16
stage: build
script:
- unset CI
- npm install
- npm run build
only:
- /^devrelease-.*$/
tags:
- docker

I am working on a react-weather application for self learning purpose. Deployed the same in gh-pages.

Repo
https://github.com/davisraimon/react-weather
When tried to integrate my application with Travis Ci, i got error as follows. It says like i have to change some env variable called Process.env.CI.$ git clone --depth=50 --branch=master https://github.com/davisraimon/react-weather.git davisraimon/react-weather nvm.install 4.18s$ nvm install stable cache.1 Setting up build cache cache.npm $ node --version v14.4.0 $ npm --version 6.14.5 $ nvm --version 0.35.3 install.npm 13.21s$ npm ci 7.45s$ npm run build > [email protected] build /home/travis/build/davisraimon/react-weather > react-scripts build Creating an optimized production build...

I added env variable in .travis.yml file.
env: process.env.CI : false
Still its showing the same error.
Can anyone help me out of this situation please...

twknab almost 2 yearsThank you for this -- after bashing awhile in this situation w/ Netlify, I caught on that the
warnings
were failing the build completely, then finally studied the output a bit more closely and saw mention of the flag...which the error output was a bit more robust. Thanks so much for helping unblock me ;P
