Error: Local workspace file ('angular.json

Question

I have travis-ci integrated with my GitHub account (https://github.com/pradeep0601/Angular5-Router-App).

When I updated @angular/cli version from 1.7.4 to 6.0.0-rc.3, the build started failing with an error:

Local workspace file ('angular.json') could not be found.
Error: Local workspace file ('angular.json') could not be found.

package.json snippet to better understand the running environment:

    "@angular/cli": "6.0.0-rc.3",
    "@angular/compiler-cli": "^5.2.0",
    "@angular/language-service": "^5.2.0",
    "@types/jasmine": "~2.8.3",
    "@types/jasminewd2": "~2.0.2",

Answer 1

If all sorts of updating commando's won't do it. Try deleting package-lock.json. And then run npm install. Did the trick for me after going through tons of update commando's.

Answer 2

For me, the issue was that I have an angular project folder inside a rails project folder, and I ran all the angular update commands in the rails parent folder rather than the actual angular folder.

Answer 3

If you don't know the version ,current project has been made, you can omit --from command and type --migrate-only

ng update @angular/cli --migrate-only

Answer 4

I had the same problem, and what I did that works for me was:

1. Inside package.json file, update the Angular CLI version to my desired one:

   "devDependencies": { ...
     "@angular/cli": "^6.0.8",
     ...
   }
   

2. Delete the node_modules folder, in order to clean the project before update the dependencies with:

   npm install
   
   ng update @angular/cli
   

3. Try to build again my project (the last and successful attempt)

   ng build --prod
   

Answer 5

Try using the below command:

ng update @angular/cli --migrate-only --from=1.7.4

It will perform the below

• Updating karma configuration

• Updating configuration

• Removing old config file (.angular-cli.json)

• Writing config file (angular.json)

Pls note that the above command should be run in the folder where you have file .angular-cli.json and it will be then replaced by angular.json.

Answer 6

Check your folder structure where you are executing the command, you should run the command 'ng serve' where there should be a angular.json file in the structure.

angular.json file will be generated by default when we run the command

npm install -g '@angular/cli' ng new Project_name then cd project_folder then, run ng serve. it worked for me
