The install procedure assumes that node is installed to your system's path. Are you on Debian? You may need to install the nodejs-legacy package.

I am on MacOS Sierra.
node is available at /usr/local/bin which is in $PATH.

For me it seems that "includes/JVMTypes.d.ts" is missing.

Some of my console output:

Whoa! Okay, that's interesting.

Also, JVMTypes.d.ts is generated in that doppioh step as part of bootstrapping. The build system (correctly) ignores type checking errors in the dev-cli step during bootstrapping. The issue is that doppioh fails for a bizarre reason.

commented

I just successfully ran:

git clone https://github.com/plasma-umass/doppio
cd doppio
npm install

I'm on a Mac, too (the version prior to Sierra; haven't made the jump yet!).

I have Node v6 installed, though. So does Travis. But I don't understand why that would cause an issue.

You're running this from an up-to-date clone of Doppio, right?

commented

I did exact the same as you tried on your Mac - all from scratch. My node is much older (4.4.5). I will check how to switch to the latest stable version...

commented

That's frustrating; 4 should still work. :(

That error message is completely nonsensical, though.

commented

Updated to v6. Same missing include - BUT its created in a later step and npm installed finished. Is this now a good or bad news? ;-)

commented

@cool2man this is intentional.

JVMTypes.d.ts is dynamically generated by Doppio itself. But it is also required for TypeScript to typecheck Doppio during compilation.

Rather than check that gigantic file in, we do the following the first time you compile Doppio:

  • Compile Doppio with TypeScript with type checking errors ignored (causing the warnings you see). TypeScript can produce JavaScript even if type checking fails, since TypeScript is JavaScript with type annotations.
  • Runs Doppio's doppioh script to generate JVMTypes.d.ts.
  • Re-compiles Doppio for type-checking. Now, if type checking fails, the build fails.
