I ran npm install prop-types --save-dev
and started getting this error
'prop-types' should be listed in the project's dependencies, not devDependencies import/no-extraneous-dependencies
Later I uninstalled the dependency by running npm uninstall prop-types --save-dev
and installed again by running npm install prop-types --save
Still the error doesn't go
'prop-types' should be listed in the project's dependencies. Run 'npm i -S prop-types' to add it import/no-extraneous-dependencies
Your package.json will look something like
{
"name": "your-website",
...
"dependencies": {
"react": "^16.10.2",
"react-dom": "^16.10.2",
"webpack": "^4.44.1",
...
},
"devDependencies": {
"prop-types": "^15.7.2",
"@types/node": "^14.0.18",
...
},
}
Make it look like
{
"name": "your-website",
...
"dependencies": {
"react": "^16.10.2",
"react-dom": "^16.10.2",
"webpack": "^4.44.1",
"prop-types": "^15.7.2",
...
},
"devDependencies": {
"@types/node": "^14.0.18",
...
},
}
by moving prop-types from devDependencies
to dependencies
After this, run npm install
or yarn install
if you are using yarn
Your devDependencies are the ones that are used while building your project. They are not present in the production of your project. When someone opens a website in a browser the code for the devDependencies is not in it
When you install a package, if you just use npm install
it will put the package in your package.json
as a dependency
. If you use npm install --save-dev
it will put the package in your package.json
as a devDependency
You should execute this command: rm -rfd./node_modules
to delete node_modules directory and then change your package.json manually like this:
"dependencies": {
...
"prop-types": <YOUR_VERSION>,
},
"devDependencies": {
...
},
and finally, run npm i
or yarn
if you're using yarn.
