The most common reason for this is a broken npm install.

Please make sure your package.json contains both @angular/compiler-cli and typescript in

+1 I am also having same problem and tried different things but nothing worked

[clydin]

Can you run both a yarn list --pattern typescript and yarn list --pattern @angular/compiler-cli and report back with the output?

Does everything work when using npm or do you receive the same error?

Do you have environment variable NODE_ENV=production like I had?
Clear this value, delete folder node_modules and file package-lock.json, rerun npm install, reassign the NODE_ENV and you should be ok.
See also npm issues

NOVE_ENV=production is what got me as well. I spent an hour and a half trying different things before I found your comment @Frigel. This means the angular tutorial is hopelessly broken for anyone with that environment variable. I got lucky.

[Jin-K]

I don't have NODE_ENV=production and have the same error

[chrisxpagan]

I also don't have NODE_ENV=production.

In environment.ts from a sample project I'm working in, I see

export const environment = { production: false,
and even in environment.prod.ts I went ahead and set the value to false.

From the shell, I entered
export NODE_ENV=development (probably not necessary?)
rm -rf node_modules package.json.lock
npm install
npm start

I still have the same error.

Could you check that your "@angular/compiler" in your dependencies is compatible with angular/cli version:

I managed to solve my own problem, and have deployed to heroku. I put them two, @angular/compiler-cli and typescript together with @angular/cli in the dependencies. Don't know if this is the solution, @angular/compiler-cli and typescript together with @angular/cli in the same place, or I just had a stroke of luck

[evanchime]

Have you done npm install -g @angular/cli@latest

[evanchime]

And you have @angular/cli, @angular/compiler-cli and typescript together in the dependencies or devDependencies, if you are on production or development respectively
