Description:

The url for binding.node file does not exist. Updating the nde-sass dependency to v4.7.2 might fix it.

Steps to Reproduce:

2. error in npm install

Output:

Small snippet of output

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-59_binding.node

Work-around steps:

1. sudo npm i -g n install the handy n tool to switch between node versions

2. n 8.5.0

3. PROFIT!! (for me at least, npm installs)

Details:

Had the same issue here. It's a huge bummer especially because I encountered it when showcasing a brand new dev to Ionic.

Downgrading to node v8.5.0 (using the handy n tool) seems to fix it.

Noticed that after downgrading node's version, the binary getting requested is https://github.com/sass/node-sass/releases/download/v4.5.3/linux-x64-57_binding.node (instead of linux-x64-59 which was giving an HTTP 404 to the caller file scripts/install.js).

The previous version throwing the error was node v9.4.0.

Hope this helps @mhartington and anyone else coming from Google.

Fix from Ionic Team
Run this command in your project after creation

npm i @ionic/app-scripts@nightly

Should fix the node-sass issue. They are planning to patch this bug where this version of node-sass is not supported in the mentioned node version.
