Ionic Framework ionic-v3

Hi community,
I just deleted node directory and then added it with, npm install.
After that ionic serve giving the following error:

Error: Cannot find module 'reflect-metadata’
at Function.Module._resolveFilename (module.js:469:15)
at Function.Module._load (module.js:417:25)
at Module.require (module.js:497:17)
at require (internal/module.js:20:19)

at Module.load (module.js:487:32)
at tryModuleLoad (module.js:446:12)
at Function.Module._load (module.js:438:3)

Can,t able to build either.Anyone have any idea about this.

Any suggestion is appreciable.

Thanks,

What is your ionic info output?
Do you always get the same error?
What does npm list -g --depth=0 return?

hi @Sujan12,
Thanks for reply.
My ionic info:

@ionic/cli-utils  : 1.15.1
ionic (Ionic CLI) : 3.15.1

global packages:

cordova (Cordova CLI) : 7.1.0

local packages:

@ionic/app-scripts : 1.3.7
Cordova Platforms  : android 6.2.3 ios 4.5.2
Ionic Framework    : ionic-angular 3.2.0

System:

Node : v6.10.0
npm  : 5.5.1
OS   : Windows 10

and npm list -g --depth=0 returns =>
±- add-cors-to-couchdb@0.0.6
±- bower@1.8.0
±- cordova@7.1.0
±- ionic@3.15.1
`-- npm@5.5.1

And I always get this error.
Thanks,

This is super old, you should upgrade this.

hi @Sujan12,
Is this is making the issue.

Possible, probably. No way to say for sure. But new versions are released as the fix problems. So not updating can cause problems.
