Nylas-mail: Unable to load plugins

[fabiopelosin]

I have installed the n1-unsubscribe plugin (https://github.com/colinking/n1-unsubscribe) and the application is unable to load it.

Step to reproduce

1. Install the application
2. Configure email accounts
3. Install the plugin
4. Wait for dialog confirming installation

Console Log

Are there any related issues?

A quick research in this repo and in the babel repo didn’t reveal any.

What operating system are you using?

OS X 10.12.2 (16C67)

What version of N1 are you using?

Version 1.0.8 (1.0.8)

Bug?

Do you have any third-party plugins installed? If so, which ones?

Same here on 1.0.8

[jontewks]

Same issue on 1.0.9, I discovered it while trying to create my own plugin. Repro steps for me

1. Go to preferences > plugins
2. Enable dev flags
3. Once Nylas Mail restarts, go back to preferences > plugins and click create new plugin
4. Save the new plugin with any name
5. Open up developer tools
6. See same error as above

Thanks for reporting this! We're going to take a look

I had the same issue with a plugin I wrote, and after investigating a bit, I solved it by doing this:

npm install babel-plugin-transform-async-generator-functions --save

I don't really know what that library does or whether that's the correct solution, but it seems to have solved the issue, because the plugin is now working...

[grinich]

This is definitely a bug. @emorikawa for some reason our plugin loader is searching in the plugin-specific node_modules folder for the babel-plugin-transform-async-generator-functions package. Any idea why this would be happening?

hi everyone, thanks for your patience! this has been fixed in https://github.com/nylas/N1/commit/bbc54ab26d98708cfe7f3f8192a14a99496fe417 and you will be able to install plugins again in our next release!
