'Error: Invalid mapping' after babel upgrade

[sajinshrestha]

After successfully upgrading from Babel 5 to 6, minifyify --map is throwing following error.

usage:

browserify entry.jsx -d -p [minifyify --map bundle.js.map --output bundle.js.map] > bundle.js

main_folder/node_modules/minifyify/node_modules/source-map/lib/source-map-generator.js:277
      throw new Error('Invalid mapping: ' + JSON.stringify({
      ^

minify without generating source maps works.

browserify entry.jsx -d -p [minifyify --no-map] > bundle.js

Using:

• node@v5.6.0
• npm@3.6.0
• browserify@13.0.1
• minifyify@7.3.3

Any ideas on how to troubleshoot this?

Never mind. After rebuilding npm-shrinkwrap.json file, this issue is fixed .
