react-scripts: command not found

Question

I am currently trying to use create-react-app which uses three different packages: react, react-scripts and react-dom. I have installed create-react-app and then when I change into the directory and hit npm start I get a react-scripts: command not found. I've ran into a lot of problems with this. I can see react-scripts is in my node_modules folder but I keep getting command not found when trying to run npm start. I tried to delete and re-install all of my node_modules but it didn't work. Anyone else having this issue?

sh: react-scripts: command not found

npm ERR! This is probably not a problem with npm. There is likely 
additional logging output above.

Answer 1

1.Delete node_modules, package-lock.json

command for deleting node_modules :

rm -rf node_modules

2.install react-scripts version 1.1.1

command for install react-scripts :

npm install react-scripts@1.1.1

3.npm install

4.now run server it will work fine.

Note : If you are a Linux user then don't forget to use sudo before npm

Answer 2

I use this in a dockerizer enviroment. I already install locally in node_modules using package.json.

so, I added this:

RUN npm install -g react-scripts
RUN npm install

That solved my confusing issue
