QUESTION
I'm working with a rails application I inherited. I'm trying to run the npm install
command but I keep getting the errors below. I tried running npm rebuild node-sass
as suggested in the output but it did not help. I'm having this problem on Ubuntu 16 as well as OS X.
ANSWER
Answered 2020-May-17 at 15:18You can use these versions:
Node: 12, NPM: 6 and node-sass: 4.12+
To fix this error, you need to fix your node and node-sass versions as per this version compatibity list. From this list, you need minimum Node 8 if you are using node-sass 4.5.3+.
I would recommend you to upgrade your nodejs and npm to latest LTS Node 12.16.3 (includes npm 6.14.4), and after that to go with node-sass
version 4.12+
. Here is how to upgrade node & npm.
To change node-sass
version, write this in your package.json: "node-sass": "^4.12.0",
.
QUESTION
I am new to React apps so please excuse me if my question has an easy answer. I have spent the last few days with Google and have not found a solution for my question.
At my new position, I have been asked to modify a current React app. The short of it is that this app was built before my time and is old. The app does not permit for a dev build. And since it does not allow for a dev build our development team can not see the component layout, props, or state along with any other goodies provided by the React Dev Tools.
My question is how do I make my app work properly with the React Dev Tools?
Other details that may help:
Files are located in ABC/app/src/common
Normally here at my employer, this would translate into a URL of:
www.ABC.com/app/
. Yet for some reason, this is not how things are set up.
Instead the app is served from a URL subdomain:
app.XYZ.com
Also, note that the URL www.XYZ.com
is not a React app - (not sure this is relevant)
Basically the build scripts create the bundle and the .min files are moved from the ABC/app/src/common
folder to app.XYZ/
.

in the root project folder.
The application should open a new browser window at http://localhost:3000 - then if you have the React DevTools Chrome extension installed you should be able to access the React DevTools tab
