Webstorm with TypeScript v1.5 Beta: “Cannot start compiler process” when using the “--emitDecoratorMetadata” option

votes

Webstorm: v10.0.3
TypeScript: v1.5.0.Beta
Nodejs: v0.12.3

The issue is the Compiler Option: "--emitDecoratorMetadata"
(which you need for Angularjs2 & TypeScript)

Two ways to transcompile:
1) GUI: Webstorm|Settings|Languages & Frameworks|TypeScript: "Command line options". Using the "--emitDecoratorMetadata" compiler option results in the compiler NOT starting.
2) CMD Line: compiling with tsc.exe from the command line using this compiler option does work, the compiler starts and runs without errors.

I have the same issue, please see this post for more information.

I'm looking forward to v10.0.4 in that case.. ;)

In the meanwhile you could use a file watcher as a workaround. That's more or less the same as calling the compiler from the command line (your second option), just that it will be executed automatically as soon as the files change:

  • Settings / Tools / FileWatchers
  • Add a new one, name it TypeScript 1.5 Compilation or something like that
  • Use following settings:
    • Select Immediate file synchronization
    • Program: C:\Users\Peter.Sample\AppData\Roaming\npm\tsc.cmd (or where ever your TS 1.5 compiler is located)
    • Arguments: -emitDecoratorMetadata -m commonjs -t es5 --sourceMap $FilePath$

That should do the job for the moment. You might however be missing the compiler messages/warnings within the dev. environment while coding.
