npm start error of development setup

[chl87256]

I did a development setup of react-chart-editor.
The installation proceeded to npm install, but after npm start, the error shown in the picture was displayed.
I tried several things but couldn't find the answer.
I thought it was a babel problem, so I upgraded and modified the index.js file, but it didn't work.
If you know how, please let me know. So thank you so much.

Would you mind trying yarn install instead of npm install?
What is your node.js version?

ould you mind trying yarn install instead of

I'm using centos7 so I can't use yarn install. The version of node.js is 6.17.1
Ah I installed yarn with npm in centos. But when I installed yarn, I got an error again.
I did a yarn install and start and got the exact same result as in the picture above.

node.js version is likely a problem. A lot of the dependencies are no longer supporting anything below v10. We're doing development with v12.
