React + create-react-app: Failed to minify error

I’m working on a React app. When running “npm run build” I receive the error below. Any help would be appreciated!

Failed to minify the code from this file:
 	./node_modules/ccxt/ccxt.js:51

Created a fresh install of “create-react-app” and ran the command “npm install ccxt --save”. Was able to reproduce the issue, same minify error occurs.

Hello - I wanted to add some additional information to this issue, since I’m experiencing it as well, but have a few extra observations.

Create-react-app build script fails with error:

Failed to compile.

static/js/main.495d93a9.js from UglifyJs Unexpected token: name (BaseError) […/~/ccxt/ccxt.js:51,0][static/js/main.495d93a9.js:53892,6]

What’s interesting, however, is that it didn’t fail before. When I first installed the ccxt package (“ccxt”: “^1.9.154”) it was building fine, I even deployed it to heroku, and it’s still live here: https://crypto-bot-trm313.herokuapp.com/ (git repo https://github.com/trm313/crypto-bot)

Yesterday, I tried to push some new changes which was when I experienced the build error for the first time. At this point, I had not modified the ccxt release I was using, although I did add some extra code with it in my app (specifically an API route that accessed the fetchTickers() function)

I tried updating to the latest release (1.9.250), but the error remains.

From the research I’ve done, I think you’re correct that CRA can’t handle any ES6 code, and as you pointed out, I’m sure ejecting the app would work as well, but obviously that’s not ideal, so wanted to share the other info I had in case it points to an easier fix
