Issue
I’m using:
$ tsc --version
Version 2.0.8
and trying to pass --experimentalDecorators option to tsc like this:
$ tsc --experimentalDecorators true greeter.ts
//error TS6053: File 'true.ts' not found.
and like this
$ tsc greeter.ts --experimentalDecorators true
//error TS6053: File 'true.ts' not found.
and like this
$ tsc greeter.ts --experimentalDecorators=true
// error TS5023: Unknown compiler option 'experimentaldecorators=true'.
but no luck. What’s the correct way to pass options to tsc?
Solution
Boolean flags are false by default so you don’t need to specify a value along with the flag. You only need to include the flag when you want to change it from false to true.
Remove true:
tsc --experimentalDecorators greeter.ts
For compiler options that expect a string, the value immediately following the argument specifies the argument’s value. For example:
tsc --module system greeter.ts
For compiler options that expect an array of strings, the individual string values should be separated by commas:
tsc --lib es5,es6 greeter.ts
The compiler assumes the value passed in is a filename if the value does not match an argument name or is not in the place of an expected argument value.
