so today I wanted to create a new Angular project using the command
ng new <projectname> and I got this error:
npm ERR! ERESOLVE unable to resolve dependency tree npm ERR! npm ERR! While resolving: [email protected] npm ERR! Found: [email protected] npm ERR! node_modules/jasmine-core npm ERR! dev [email protected]"~3.6.0" from the root project npm ERR! npm ERR! Could not resolve dependency: npm ERR! peer [email protected]">=3.7.1" from [email protected] npm ERR! node_modules/karma-jasmine-html-reporter npm ERR! dev [email protected]"^1.5.0" from the root project npm ERR! npm ERR! Fix the upstream dependency conflict, or retry npm ERR! this command with --force, or --legacy-peer-deps npm ERR! to accept an incorrect (and potentially broken) dependency resolution.
I literally tried everything, I updated
Angular cli again, download and installed
npm audit, and a lot of other things but nothing happened.
Also as you can see error told me to use the command with
--force, I tried but nothing happened, and with
--legacy-peer-deps, I get the error as unknown option.
What is bothering me the most is that everything was working completely right last night and I changed nothing at all but suddenly I’m getting this error today.
Open the folder you create with ng new and open the
package.json file. In
devDependencies change the version of "jasmine-core"
3.8.0 and "karma-jasmine-html-reporter" from
1.6.0 and save it. Then go back to Terminal and go to your project and run
npm install. Now it works and you can run
"jasmine-core": "~3.8.0", "karma-jasmine-html-reporter": "^1.7.0"
