[Werner-Swart-83]

I have the same issue, but running node 6.10.1 on the same environment and using angular version 4.

[shumbo]

Having a exact same issue.

[cdibbs]

Seems to be related to #5131. Resolved in the same way (upgrade typescript to latest).

[Werner-Swart-83]

Updated my local typescript to latest and changed my tsconfig.json to tsconfig.app.json and everything worked again.

[danielptm]

I am having the same problem, and updating typescript and changing tsconfig.json to tsconfig.app.json did not help.

add @angular/compiler-cli to package.json and install it (same version as your other @angular libs. It's required as per the error message :)

Easiest way to debug any CLI error is to just generate a new project and compare files like your package.json: ng new temporary

[danielptm]

@intellix solved the problem for me. I added the line

...
"@angular/compiler-cli":"^2.3.1",
...

version was the same as my other dependencies.

[codestation]

I have the same error with a new empty project that i am trying to deploy on heroku so this isn't an upgrade problem:

@codestation if you're building on Heroku, you need to move compiler-cli amongst a few other packages to "dependencies" as Heroku only installs packages in production mode.

Here's an example package.json that works on Heroku with a basic server. I keep seeing this daily, I guess it's time for me to write my first blog post :)

{
  "name": "wildcase",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {

    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "start": "node server",
    "postinstall": "ng build --target=production -e ${NODE_ENV:-production} --aot"
  },
  "private": true,
  "dependencies": {
    "@angular/cli": "1.0.0",
    "@angular/common": "^4.0.0",

    "@angular/compiler-cli": "^4.0.0",
    "@angular/core": "^4.0.0",

    "@angular/http": "^4.0.0",
    "@angular/platform-browser": "^4.0.0",

    "@angular/router": "^4.0.0",
    "bootstrap": "4.0.0-alpha.6",
    "core-js": "^2.4.1",
    "font-awesome": "^4.7.0",
    "rxjs": "^5.1.0",
    "typescript": "~2.2.0",

    "protractor": "~5.1.0",
    "ts-node": "~2.0.0",
    "tslint": "~4.5.0"
  }
}

Notice how I moved @angular/cli @angular/compiler-cli and a few others to dependencies

[codestation]

Thanks, that was the problem. Moved cli, compiler-cli and typescript out of devDeps and it worked.

[elversace]

@intellix where i put that code pleas ???

[intellix]

@elversace - If you're deploying to Heroku, add it to dependencies, otherwise add it to devDependencies inside package.json.
...or go to console and: npm install --save @angular/compiler-cli

Created a blog post about Heroku deployments.

[rfball]

A long litany of comments. Still, I am not sure what the I need to do with respect to my initial posting???

[intellix]

@rfball npm install --save @angular/compiler-cli

[rfball]

@intellix Thanks for the quick response! Just tried this but this is a long list of "UNMET PEER DEPENDENCIES" . Is there a way to do something like the following, in order to start form scratch.
1 fix the package.json (and/or other files)
2 remove any existing files
3 reinstall from scratch
Thanks for your help!
