ng serve command not working angular 5

Question

If I run ng serve, getting this error

ng : The term 'ng' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:1 + ng serve + ~~ + CategoryInfo : ObjectNotFound: (ng:String) [], CommandNotFoundException + FullyQualifiedErrorId : CommandNotFoundException

I have tried npm run ng serve, getting this error

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

I have uninstall @angular/cli and cleared the cached, again installed but facing same issue.

Kindly suggest.

Solution 1

This could be due to different versions of angular-cli. Check the version of angular-cli, you should not have version 6, but use 1.7. Cause in angular 6 the configuration is in angular.json file. In version 1.7 the configuration is in angular-cli.json

Solution 2

> npm start

will solve your problem as it solved mine

It gave error because you installed latest version of Angular CLI and your project built with may be older version of angular Try to run: npm install -g @angular/[email protected]

Thanks for reponse, I tried this but facing same issue

[Admin]

npm i -g @angular/cli, or if it's installed locally, try running npm run serve after you added "serve": "ng serve" to your package file

[Parth Savadiya]

From which path you are trying to run? that path contain package.json and angular.json file?

[mjck]

where I can see the path or update

[Admin]

This should be a comment

[mjck]

Thanks for the update, I have installed npm install -g @angular/[email protected], removed the node modules folder and installed it again. if I run npm run ng serve its working fine, but if I run ng serve its not working

I challenge this solution. If we look at the documentation and other online articles, angular-cli 1.7 contains vulnerabilities, due to which latest version of angular-cli is preferred. Answer is Okay if you are not putting something in production.
