create-react-app build process take too long

Question

We received from a partner a front end to interact with our API (builed in node.js) builded using create-create-app, after cloning the repo from our partner git, the npm start command works, I can locally test the app interacting with the API with no problems at all. also in my local machine the npm run build command works great, im able to build and run the app with serve build command.

the problem comes after cloning the repo into the Amazon AWS EC2 instance, im able to clone the repo but after running npm install , when running npm run build the process just stay forever in the following message:

sudo npm run build

> sensores@0.1.0 build /var/www/smartdots-frontend
> react-scripts build

Creating an optimized production build...

after 20 minutes or so the process keep hanged and lastly this is the final message:

> sensores@0.1.0 build /var/www/smartdots-frontend
> react-scripts build

Creating an optimized production build...
The build failed because the process exited too early. This probably means the system ran out of memory or someone called `kill -9` on the process.

I've tested the npm run build in several machines, with different OS, and it always run fine, in really desperated about this, i've tried building the app as root, changing folder permissions and ownership, and nothing works, building the app in another computer and serve it in the AWS machine also doesn't work

Answer 1

It does sounds like it's a memory issue, particularly this line:

The build failed because the process exited too early. This probably means the system ran out of memory or someone called The build failed because the process exited too early. This probably means the system ran out of memory or someone called kill -9 on the process. .

You can check it by running the command top inside the terminal and see the memory usage.
