Not work "yarn" if Node version 12+

Prerequisites

• Using yarn
• Using node 12.x

Expected Behavior

Then i using the latest version of Node.js (now it is 12.1.0), there is a mistake at installation of dependences (node-sass):

yarn

It happens because of the old version of node-sass (in the project: ^4.10.0, but for work with Node.js v 12, the version of node-sass 4.12 is necessary).

Possible Solution

Therefore it is necessary to update manually node-sass to the latest version, before execution of the command of yarn:

node i node-sass

Steps to Reproduce (for bugs)

1. Install latest Node.js version (12.x)

2. git clone … in folder

3. yarn

4. Result: Error (can’t install node-sass)

Your Environment

• Node version : 12.1.0
• Operating System and version : Windows 10

P.s.: Maybe I know not enough how work yarn, but it caused in me a problem.

Same problem for me. Updating node-sass in package.json to use version ^4.12.0 fixed the problem for me.

Updating node-sass to 4.12.0 fixed it for me as well. (I’m also using Node v12)
