The term 'CI=false' is not recognized as the name of a cmdlet, function, script file, or operable program

Question

I'm trying to gitlab's CI/CD and was making a yml-file that build the project. The problem is that I get the following:

$ npm run build
 > [email protected] build C:\GitLab-Runner\builds\QLuLhspz\0\I416547\s4-software-fun-frontend
 > react-scripts build
 Creating an optimized production build...
 Treating warnings as errors because process.env.CI = true.
 Most CI servers set it automatically.
 Failed to compile.

Now it says warnings are set to errors so what I tried doing in my yml-file was adding CI=false:

stages: ["build", "test", "deploy"]

before_script:
    - npm install
    - CI=false

build:
    stage: build
    script: npm run build

test:
    stage: test
    script: npm run test

deploy:
    stage: deploy
    script: npm run start

But than it says the command is not recognized. Is it because it's not a powershell command or does react.js use the node-command? (either way it doesn't work)

Sources tried:

• npm ERR! code ELIFECYCLE
• https://github.com/facebook/create-react-app/issues/3657

EDIT: found the problem....instead of doing it in the yml-file it should've been done in the project itself. How to set environment variable in React JS..?

Answer 1

For anyone having this issue because they're running script using powershell:

$env:CI=$false; npm run build;

$env:CI is how you set the environment variable inline in powershell.

Answer 2

Another way to disable CI using windows is adding build-win script to package.json:

  "scripts": {
    "build": "CI=false rescripts build",
    "build-win": "set CI=false&&rescripts build"
  }

And then running npm run build-win. Note that && must not be surrounded by spaces.

Answer 3

You'll need to set the environment variable along with running each relevant command: CI=false npm run build and CI=false npm run build.

If setting it as a before_script, GitLab CI tries to run it as a stand-alone command (when actually it's just setting an environment variable).

Is it because it's not a powershell command or does react.js use the node-command?

Powershell is Windows-only, whereas GitLab CI commands are bash commands that run on Linux. React isn't related to Node.js, though create-react-app does use it. Environment variables that are set can be read by any code, regardless if it's Node.js or anything else.

Answer 4

CI=true is needed in case you would like to process test during the deployment but it can be easily archived by setting a flag via package.json

 "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "CI=true react-scripts test"
  }

Answer 5

When I wanted to create a build folder using npm run build command, this problem showed up. After trying the above answers (CI= false or CI= true in the script object of the package.json I still get the same error.

"scripts": {
    "start": "react-scripts start",
    "build": "CI= false react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

Edit (31.10.2021): I found the solution that remove the bothersome problem in another post. This is the related post: npm ERR! [email protected] build: `CI= react-scripts build` Thank you @manchit197
