Complains that `postcss` is not installed

[satazor]

Hi,

I've followed the installation steps but I'm getting the following error:

SublimeLinter: chdir not set or invalid, using /Users/satazor/Work/own/redux-boilerplate/src/app/components/css 
SublimeLinter: stylelint: application.css ['/usr/local/bin/node', '/Users/satazor/Library/Application Support/Sublime Text 3/Packages/SublimeLinter-contrib-stylelint/stylelint_wrapper.js', '@'] 
SublimeLinter: stylelint output:
module.js:339
    throw err;
    ^

Error: Cannot find module 'postcss'

But I clearly have postcss installed (both stylelint and postcss are installed locally).

$ node

require('postcss') { [Function: postcss]

Thoughts?

Hi, I've not seen this before but I've just made some changes to the plugin to support using the stylelint CLI. Can you let me know if this resolves your issue once you've updated to 1.0.4?

Cheers

@kungfusheep I'm also having this issue, I'm updated to 1.0.4.

[danielkcz]

Now I see this is related to #18 too.

I'm also having this problem, though I suspect it could be a deeper issue (I am running nvm, I haven't dug to much into that yet...):

Without nvm:

$ npm i postcss -g
npm WARN engine postcss@5.0.19: wanted: {"node":">=0.12"} (current: {"node":"0.10.32","npm":"2.1.4"})
postcss@5.0.19 /usr/local/lib/node_modules/postcss
├── js-base64@2.1.9
├── source-map@0.5.3
└── supports-color@3.1.2 (has-flag@1.0.0)

$ which node
/usr/local/bin/node

$  node
> require('postcss')

With nvm:

$ nvm use 5
Now using node v5.6.0 (npm v3.6.0)

$ which node
/Users/xxxx/.nvm/versions/node/v5.6.0/bin/node

$ npm i postcss -g

Running the above in my project directory:

$ npm ls postcss
reactjs-boilerplate@2.4.0 /Users/xxxx/my-project
├── UNMET PEER DEPENDENCY jshint@^2.5.0
└── postcss@5.0.19

$ npm ls stylelint
reactjs-boilerplate@2.4.0 /Users/xxxx/my-project
├── UNMET PEER DEPENDENCY jshint@^2.5.0
├─┬ lint-staged@0.1.1
│ └── stylelint@3.2.3
└── stylelint@4.5.1

$ node
> require('postcss')
{ [Function: postcss]
  plugin: [Function],
...
}
> require('stylelint')
{ [Function: creator]
  postcss: { [Function] postcssPlugin: 'stylelint', postcssVersion: '5.0.14' },
...
}
>
$

Certainly looks like an issue resolving the dependencies outside of the project directory.

[danielkcz]

Personally I don't think it should use postcss at all. If you see my PR #19, I simply used NodeLinter to call stylelint directly. I am using that for like month now and works nicely.

[learntoswim]

@FredyC I tried to use the changes from your PR, I received this error:

SublimeLinter: stylelint: styles.css ['/Users/xxxx/my-project/node_modules/.bin/stylelint', '--config', '/Users/xxxx/my-project/.stylelintrc'] 
SublimeLinter: stylelint output:

/Users/xxxx/my-project/node_modules/stylelint/dist/rules/indentation/index.js:230
var hierarchyMap = new Map();
                       ^
ReferenceError: Map is not defined

I it's still somewhat nvm related? Hmm...

[danielkcz]

Well, the Map is part of ES6, so most likely you have outdated NodeJS. I am not entirely sure how to find which version supports these new collections, but just try to install latest with nvm.

[learntoswim]

That's my point. My default node instance is 0.10.32. I use nvm to use 5.x... So there's something to think about there.

[danielkcz]

Well but that's not really NVM or this package related. Error itself pops from the stylelint itself which is written using ES6. So if anything you can complain there that they should provide ES5 compatible build. But I would suggest to just forget about that old NodeJS especially when you can afford luxury of NVM (I don't have it on Windows).

[learntoswim]

Exactly. Hopefully this helps others.

[kungfusheep]

hi - please see my comments on #19. cheers.
