[jackywang615]

The same error.
angular-cli: v1.0.0-beta.20-1
OS: windows 10 x64
nodejs: 7.0.0

[coryrylan]

Got the same error with same stack trace
angular-cli: v1.0.0-beta.20-1
OS: macOS Sierra
nodejs: 6.7.0

[b4youleap]

Can't even run ng version ... same error
angular-cli: v1.0.0-beta.20-1
OS: Windows 7 x64
nodejs: 5.12.0

[mcourville]

Same here :(
angular-cli: v1.0.0-beta.20-1
OS: Mac os 10.10.1
nodejs: 7.0.0
npm: 3.10.9

[monfa-red]

"ng " doesn't run anymore!, I get the same error
event after installing it globally, can't event run "ng -v"!

angular-cli@1.0.0-beta.20-1
OS: Kubuntu 16.04
node: v6.9.1
npm: 3.10.8

[evrins]

Same problem
angular-cli@1.0.0-beta.20-1
OS: Mac OS 10.12.1 (16B2555)
node: v7.1.0
npm: 4.0.2

[monfa-red]

A temporary fix that worked for me:
Add these to your package.json (change the version of @angular/compiler-cli to the exact same version you have for @angular/core)

 "@angular/compiler-cli": "2.2.0",
 "reflect-metadata": "^0.1.8"

And for running ng ... don't use your global angular-cli , instead add it to your package.json and run it with npm (so it's gonna use your local angular-cli)

 "scripts": {
    ...
    "build-my-app": "ng build --prod --aot --xyz"
 },

and to run it

 npm run build-my-app

[koujala]

I managed to get this working this way
npm i -g reflect-metadata

However I installed angular-cli locally ( just like @monfa-red )
npm i angular-cli

Followed by these
npm i reflect-metadata
npm i zone.js@^0.6.21
npm i -g rxjs@5.0.0-beta.12
npm i @angular/core
npm i @angular/compiler-cli
npm i @angular/compiler

Followed by ng -v
angular-cli: 1.0.0-beta.20-1
node: 6.9.1
os: win32 x64

[evrins]

solve this by rolling back to the last usable version 1.0.0-beta.19-3
npm i -g angular-cli@1.0.0-beta.19-3

[harilalinapp]

Same issue. I tried to update my application to 20-1 and its breaking. So i rolled back to 19-3
I think it's related to some dependency.

[hansl]

Looking into it. I'm going to release 20-2 soon. Stay tuned.
