failed to load plugin flowtype declared in package.json

Cause of error failed to load plugin flowtype declared in package.json

This error failed to load plugin flowtype declared in package.json occurs while starting the new project create-react-app. One can get this error in the terminal part while running the npm start command. The error appears as follows:

Solution

An eslint plugin is a unique npm package for eslint that offers more rule definitions (rules), environments, processors, and configurations for various setups of suggested / default rule values. A flag to activate a certain plugin after installation with npm is all that the plugin’s property in. eslintrc. js does.

Create-react-app contains some checks that break your build if you have eslint issues, thus it seems sensible that they are connected when you run npm start.

The problem one can see here relates to a node feature called subpath exports that eslint is using, although support for it varies depending on how the library is used. When employed with humor, for instance, it can become problematic.

Another way to solve this error is by deleting the following code from the package.json:

"eslintConfig": {
"extends": [
"react-app",
"react-app/jest"
]
}

Another solution is that the node version that the user is using is not up to date. One must update it to the new version to solve this issue. Another solution can be by switching the node version to the LTS version 16.14.2.
