Need help: Error occurs when trying to run command npm start

[chriszhangusc]

Hi guys, I tried to run the app locally, after I clone the git repo, the 'npm install' worked just fine but when I ran 'npm start' I got the following output, I am using a Mac OS X with node version: 7.5.0 and npm 4.2.0. Not sure what is going on here.

webpack-dev-server --progress --colors --hot --config ./webpack.config.js

OK, after switching my node version to 6.9.5 by nvm, everything seems to be fine now.

@MiniPekka I had the same problem, because I switch node versions a lot. Anything we could do against it? In a dreamworld it would work for everyone.

[chriszhangusc]

@rwieruch After some research I have found out it was the version of sass-node that caused the incompatibility with node 7 when trying to run npm start, my solution would be upgrade node-sass to 3.8.0. It also gets rid of those cpp compiling warnings when we do npm install.

Seems to be a general problem with Sass and changing Node environment. You can run npm rebuild node-sass.

Issue: https://github.com/sass/node-sass/issues/1527

[rwieruch]

Added .nvmrc file. When you use nvm to manage your node versions, you can type nvm use to use the according node version for this project.

I ran into this problem again with node 8.0 installed on my machine, and to make sure new user with node 8 does not get confused by this issue, I think we should update the node-sass to 4.5.3 to resolve this issue. (Also see: https://github.com/sass/node-sass/issues/1984)

[rwieruch]

Oh my .... Sass :) Did it work for you when you updated node-sass? If so, then I would say go for it 👍 I guess it would be great to update it for its sister project as well: https://github.com/rwieruch/favesound-mobx
