I am trying to install and run react-devtools. I am following this guide to do that: https://github.com/facebook/react-devtools/blob/master/packages/react-devtools/README.md

The install seems to go ok:

To verify it installed correctly I do this command:

And I go to that directory and verify there is a folder called react-devtools.

To open the tools the docs indicate I should do this:

Back in my project directory I run this command:

And it says command not found. So it looks like I have installed the devtools, but I am unable to open them. What am I doing wrong?

Maybe this is what you want

Fix not run react-devtools

Option 1:

npm uninstall -g react-devtools
npm uninstall -g electron
npm install -g --verbose react-devtools

Option 2: (Fix in Linux, MacOSX)

sudo npm install -g react-devtools --unsafe-perm=true

Refer: react-devtools-command-not-found

To run react-devtools you can run either of the following commands depending on your package manager.

If using yarn: yarn run react-devtools

The real problem here is you are not giving "super user" permissions for the node package manager for installing the "react-devtools" globally.

Try this command it will fix your problem

sudo npm install -g react-devtools

When ignore the -g parameter in the command npm will install the react-devtools in directory that you currently working in. In your case the home directory.
