Package Exports

spawn-sync

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (spawn-sync) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

spawn-sync

Polyfill for child_process.spawnSync.

On iojs and node >= 0.12 it will just export the built in child_process.spawnSync. On platforms that support compiling native modules it uses the thread-sleep module to wait for an output file to exist in a tight loop. In this way it gains excellent cross platform support, but don't expect it to be efficient on all platforms.

Installation

npm install spawn-sync

If this fails, you can try one of the following things:

You can install using --unsafe-perm, which will fix any permissions issues.

npm install --unsafe-perm spawn-sync
You can install using --ignore-scripts, which will skip native compilation. You'll get a warning if you try to require the module, but everything should still work.

npm install --ignore-scripts spawn-sync
You can try updating npm, since this seems to fail on some older versions of npm:

sudo npm install npm -g
You can upgrade to the latest version of node or iojs. This will make native compilation unnecessary. You can then use --ignore-scripts without getting a warning if you still have trouble.

Usage

var spawnSync = require('spawn-sync');

var result = spawnSync('node',
                       ['filename.js'],
                       {input: 'write this to stdin'});

if (result.status !== 0) {
  process.stderr.write(result.stderr);
  process.exit(result.status);
} else {
  process.stdout.write(result.stdout);
  process.stderr.write(result.stderr);
}
