React js compile error

Question

I am new to react, but I am stuck with this error since last week. somebody help me, please! Cannot read property 'thisCompilation' of undefined

npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! althaqalyn@0.1.0 start: react-scripts start npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the althaqalyn@0.1.0 start script. npm ERR! This is probably not a problem with npm. There is likely additional log ging output above.

Answer 1

What I see from the given issue is that react-script is unable to install from package.json file, if you are trying to install all the dependencies. You can try to run below commands to install the dependencies and verify them.

npm install react-scripts --save

npm audit fix

Answer 2

I had the same problem. Here is my debug.log

I loaded nodemon and started the server using 'nodemon' instead of npm start. It looked like there were ambiguous start scripts. I don't know if this is a fix, but I was able to continue working, so that's a win in my book!
