Installing node-sass and rebuilding/using it results in module not found

[aouaki]

Hello,

Do you want to request a feature or report a bug?
Bug

What is the current behavior?

I install node-sass@^3.13.0 using yarn 0.17.8. I then run npm rebuild node-sass and it outputs :
Error: Cannot find module 'sax'
The missing is sometimes different (happened to be has too).

It also happens without running npm rebuild node-sass. When using node-sass without rebuilding it, I encounter the same error.

Could be related to sass/node-sass#1804 but on this issue they say it's fixed on yarn v0.17.7, while on 0.17.8 it isn't for me.

Thanks,

Installing with yarn and then rebuilding with npm doesn't seem like a good idea to me.

I have tried the following snippet in both macOS & Ubuntu and it's working using yarn v0.17.8.

var sass = require('node-sass');
sass.render({
  file: 'test.scss'
}, function(err, result) {
  result && console.log(result);
});

So, I would suggest you to do a yarn add --force node-sass instead of npm rebuild node-sass

[hassankhan]

I can confirm that node-sass on Yarn v0.17.8 is breaking my CI at the moment. I haven't yet updated Yarn on my own machine (still on v0.17.6).

Running yarn add --force node-sass instead of npm rebuild node-sass works but then my webpack script has the same module issue when running node-sass to compile the scss files:

[bestander]

@aouaki, can you run yarn cache clean, does it help?

[aouaki]

@bestander Doesn't change anything 😞. I don't think that heroku's deployments use yarn's cache anyway. @hassankhan do you still have the issue ?

[hassankhan]

Haven't yet had the chance to update Yarn and check, will do later today and report back

[aaugustin]

I'm facing the same issue when deploying to Heroku.

I'm using yarn 0.18.1. I declare that in the "engines" section of package.json, which Heroku honors.

``` remote: -----> Installing binaries remote: engines.node (package.json): 6.3.0 remote: engines.npm (package.json): unspecified (use default) remote: remote: Downloading and installing node 6.3.0... remote: Using default npm version: 3.10.3 remote: Downloading and installing yarn (0.18.1)... remote: Installed yarn 0.18.1 ```

The first build after clearing Heroku's build cache succeeds. Further builds fail to compile my SASS stylesheets with webpack beacuse node-sass fails to find the vendor directory.

``` remote: ERROR in ./amalfi/documents/main.sass remote: Module build failed: ModuleBuildError: Module build failed: Error: ENOENT: no such file or directory, scandir '/tmp/build_fecf70d99758306b4e17bbcbf75d69fa/node_modules/node-sass/vendor' remote: at Error (native) remote: at Object.fs.readdirSync (fs.js:951:18) remote: at Object.getInstalledBinaries (/tmp/build_fecf70d99758306b4e17bbcbf75d69fa/node_modules/node-sass/lib/extensions.js:122:13) remote: at foundBinariesList (/tmp/build_fecf70d99758306b4e17bbcbf75d69fa/node_modules/node-sass/lib/errors.js:20:15) remote: at foundBinaries (/tmp/build_fecf70d99758306b4e17bbcbf75d69fa/node_modules/node-sass/lib/errors.js:15:5) remote: at Object.module.exports.missingBinary (/tmp/build_fecf70d99758306b4e17bbcbf75d69fa/node_modules/node-sass/lib/errors.js:45:5) remote: at module.exports (/tmp/build_fecf70d99758306b4e17bbcbf75d69fa/node_modules/node-sass/lib/binding.js:15:30) remote: at Object.

As a workaround, I added:

yarn remove node-sass
yarn add node-sass@latest

to my deployment script, after installing dependencies but before running webpack.

This allows me to deploy my app with yarn, but negates most of the speed advantage of yarn over npm (it feel like 3 x 15 seconds instead of 1 x 45 seconds — I didn't time it precisely).

[aaugustin]

I came across multiple reports of this issue in the node-sass and yarn repositories. Maintainers of node-sass believe it's a bug in yarn.

It would be useful to consolidate discussions in one issue, in the repository of the project where the fix belongs.

[kjs3]

@aaugustin: Did you run…

yarn remove node-sass
yarn add node-sass@latest

…in postinstall, heroku-postbuild, or some other hook?
