Cannot read property minify of null

[estrattonbailey]

Hey! Thanks for the lib.

I might be totally missing something, but when I installed from npm all I got was the README.md and the package.json. It could be because npm inherits the .gitignore config if it's available, so a blank .npmignore should override it, in my experience.

Happy to make a PR, but figured that you'd want to determine what else npm ignores and it's tiny tiny change 😛

UPDATE: I had manually compiled this lib locally and ran into errors, a la:

NODE_ENV=production webpack --config webpack.production.config.js -p

/Users/eric.bailey/Sites/quanta-server/node_modules/butternut-webpack-plugin/node_modules/butternut/dist/butternut.cjs.js:1662
				this.alternate.minify( code );

I just needed to remov the -p flag from the webpack command. My bad! Updating here in case it helps someone else.

Arrrrgh totally my bad, can you install the 0.0.6 version?

[estrattonbailey]

Sweet, thanks!

[pedronauck]

The same error is happening here and I'm using version 0.0.6 😢

[balthazar]

Hey pedronauck! Don't cry! 😄
Can you check the content of the package installed? The version in the module package.json is 0.0.6? Checking the unpkg returns me the correct index.js

[pedronauck]

Yes, it's the same file, and that's the error

/Users/pedronauck/Projects/personal/projects/shazam/node_modules/butternut/dist/butternut.cjs.js:1662
				this.alternate.minify( code );
				              ^

TypeError: Cannot read property 'minify' of null

I'm using Webpack 2!

I think this is an issue with butternut itself rather than the module then, a similar issue has been reported in #123, as @estrattonbailey said, you need to remove the -p option.

Hi. I had the same error:

Cannot read property 'minify' of null

The option that cause it is:

'process.env.NODE_ENV': JSON.stringify('production')

[joezimjs]

Yup, agree with @gombek. It's breaking when NODE_ENV is "production". If I just change what the DefinePlugin's value for process.env.NODE_ENV equals, it doesn't break anything, but if NODE_ENV is actually set to "production", this error shows up.

Note: I'm currently minifying for both dev and prod, so it's not a simple mistake of not running Butternut in dev.

[balthazar]

Reopening for visibility, it's quite annoying that setting the production env does this, since butternut is intended to be run only with this one

[RReverser]

Hmm, just run into this, but it looks like relevant issue Rich-Harris/butternut#137 might be already fixed on master, but this plugin depends on "butternut": "^0.3.5" so versions 0.4.* (including latest 0.4.6) are not installed.

@apercu Could you bump the dependency or maybe even make it peerDependency and let people install preferred version of babili on their own?

[balthazar]

Bumped all deps in 0.1.0, let me know.
