After cloning your repository, I installed dependencies using 'npm install', then I run the command 'npm start' and faced this error. Kindly help me.

Dear @KrGyan
I installed npm install -g @angular/cli.
But it occurs same error. How can I fix it?

Regards,
Alex

[SkMamtajuddin]

Thanks @KrGyan ! its work when update cli to 1.2.6

hmm, I updated cli to 1.3.1 But it doesn't still work for me. what' the reason?

[SkMamtajuddin]

@alexandra1030 pls use 1.2.6 version and reinstall

@SkMamtajuddin oh, yeah, i'll try it. 👍

[JohannesFerner]

@SkMamtajuddin @alexandra1030
I was on 1.5.0 (global); Downgraded to 1.2.6 (global) ...
be aware of

$ ng -version
Your global Angular CLI version (1.2.6) is greater than your local
version (1.0.3). The local Angular CLI version is used.

To disable this warning use "ng set --global warnings.versionMismatch=false".

so do not update via -g but update the local version.

Then it worked for me

[akilmakda]

run :npm install enhanced-resolve@3.3.0

in your pakage.json file.. in script tag replace this "ng build --prod" with "ng build --env=prod". It will reolve the problem.

[chozharajan]

i updated my local angular cli to 1.2.6.

its worked

[kamalakkanni]

I am using angular5.Me also getting this issue

[Mr-Plants]

@akilmakda thank you!it really work for me
