npm run prepublish => ReferenceError: Unknown plugin

Hi,
I have an error when trying to run "prepublish" :

ReferenceError: Unknown plugin "'transform-es2015-modules-umd'" specified in "base" at 0, attempted to resolve relative to "src"

I have Node v6.9.5 on Windows 10

Do you know how to resolve the problem ?

Thank you

Hi @damien916, I am not familiar with that error. Have you tried deleting the node_modules directory and running npm install?

[damien916]

Hi @ethanselzer, yes i tried, but it still not work.
Finally it's work by removing the plugin "transform-es2015-modules-umd" from prepublish command in package.json
Thank you

@damien916 - I'm glad you found a workaround! Sorry for the trouble. If I were starting the project today, I probably would not support UMD/AMD modules, but because the package supports them today, I think it is best not to break that. Instead I think I will add a new command as an option for publishing to CommondJS only (prepublish-cjs). I will also add a section to the readme, explaining how to use the example project in development, and reference this issue. Thanks for opening this issue and raising my awareness to the problem!

"prepublish-cjs": "src --out-dir ./dist"

@damien916 - I added the command prepublish-csj, as we discussed, and updated the Development section of the readme with basic instructions on using the example project for development of react-image-magnify. It includes a link to this issue. Please have a look. Thanks!
