Workaround

Lock TypeScript version at 2.0.0 in package.json.

-"typescript": "^2.0.0"
+"typescript": "2.0.0"

@ValeryVS see #1901

[ValeryVS]

Right, duplicate. Missed that issue.

[rakibler]

Sorry, mine sort of had a bad title

Having the same problem, See issue 1887 for more details.

Check out dematic-rodrigo-silveira's post on #1919. I will summarize below. Huge thanks to dematic-rodrigo-silveira! I was tearing my hair out about this one.

For a new project, there are a few steps:

Update Node to 6.5 and npm to 3.10.3

• You can check your versions with node -v and npm -v respectively.
• These can be both be updated from the nodejs.org download site. The installer installs both of them. https://nodejs.org/en/download/current/

Update Typescript to 2.0+

• check with tsc -v
• npm install typescript@next will update you to 2.1.0

Follow the README's instructions on installing the new cli

• npm uninstall -g angular-cli
• npm install -g angular-cli@webpack
• npm new projectname Creates your new project
• cd projectname moves you into the newly created directory

Modify project dependencies

• Open package.json from your apps root directory
• Under "devDependancies", locate "typescript".
• Change "^2.0.0" to "2.0.0". This locks yourproject at typescript 2.0.0 instead of 2.1.0.
• Save

ng serve
app works!
ng init
npm install --save-dev angular-cli@webpack to set the correct cli

Once this is complete, you should be able to serve and test without issues. I am loving the new cli.

Thank you to the CLI team!
Happy coding!

The problem with the solution from @SeekingMonkey is that now, RC6 has been released and it appears to have a dependency on 2.0.2 specifically . What now?

[aszechlicki]

we probably need to wait with updating until angular-cli team fixes that
fortunately RC6 isn't as revolutionary as RC5, it's mostly cleanup so waiting a couple days (hopefully) won't change much

Very weird issue. Whenever I scaffold a new project with angular-cli: 1.0.0-beta.11-webpack.8 and try to build the project for the first time, I get a list of errors.
My workaround was simply to uninstall / install typescript@beta and the project builds fine:
npm uninstall --save-dev typescript
npm install --save-dev typescript@beta
ng build

I followed the process outlined by @SeekingMonkey. ng serve still threw the same list of exceptions. Then I tried @emyann's process and it started working.

[Blak3Nick]

I concur with @CalvinDale, I, also, could not get the process @SeekingMonkey described to work, but @emyann's worked like a charm.
