Versions of @angular/compiler-cli and typescript could not be determined. The most common reason for this is a broken npm install.
Please make sure your package.json contains both @angular/compiler-cli and typescript in devDependencies, then delete node_modules and package-lock.json (if you have one) and run npm install again.

I solved The Issue after 23hrs of research and continues trails
Sollution:
Add the three { “@angular/cli”: “1.5.2”, “@angular/compiler-cli”: “^5.0.0”, “typescript”: “^2.4.2” } in “dependencies” too so these will be installed without error I repeat again make sure the above three are available in “dependencies” and Devdependencies too…
It will work for sure… If you have any doubts mail me or call me
Thank you, everyone…
I don’t have NODE_ENV=production and have the same error
+1 I am also having same problem and tried different things but nothing worked
The same issue was for me too.
Works fine in dependencies and devDep.
Do you have environment variable NODE_ENV=production like I had? Clear this value, delete folder node_modules and file package-lock.json, rerun npm install, reassign the NODE_ENV and you should be ok. See also npm issues
I managed to solve my own problem, and have deployed to heroku. I put them two, @angular/compiler-cli and typescript together with @angular/cli in the dependencies. Don’t know if this is the solution, @angular/compiler-cli and typescript together with @angular/cli in the same place, or I just had a stroke of luck
Closing as there seem to be suggestion to address the problem.
This problem seems to depend on your environment. If you are running npm in production mode (
npm install --prodor if you haveNODE_ENV=productionsomewhere), then onlydependenciesin yourpackage.jsonwill be installed. The packages indevDependencieswill not be installed.But many packages in
devDependenciesare needed to build your app. So you either don’t install in prod mode, or move the neededdevDependenciesover todependencies.after creating ng new Projectfoldername when i run “npm start” Im getting this error

I tried reinstalling i tried force install many ways but everything is not working I’m trying from Last 18 Hrs trying many ways to Overcome none of them is working. Anyone Help me
By default, npm install will install all modules listed as dependencies. With the --production flag, npm will not install modules listed in devDependencies. either we can go for @sudhakar216 solution of editing the package.json or
To install dev dependencies, npm --production=false install will work even with NODE_ENV=production.
Or you can run NODE_ENV=development npm install

Good to see my 23 hrs of searching is useful for people feeling good in heart thanks for posting Atereshkov
Could you check that your “@angular/compiler” in your dependencies is compatible with angular/cli version:
