No error output when invoked from command line

[mgiuffrida]

The Node module doesn't output error messages from the command line. For example, this should result in a parse error, but outputs a blank line nothing and has an error code of 0:

% echo '{()};&$*#_;' > blah.js
% node node_modules/.bin/google-closure-compiler-js blah.js

% echo $?
0
% node node_modules/.bin/google-closure-compiler-js -v
20161201.0.1

But:

require('google-closure-compiler-js').compile(
    {jsCode: [{path: 'blah.js', src: '{()};&$*#_;'}]}
);
{ compiledCode: '',
  errors:
   [ { file: 'blah.js',
       description: 'Parse error. invalid parenthesized expression',
       type: 'JSC_PARSE_ERROR',
       lineNo: 1,
       charNo: 3 } ],
  warnings: [] }
