Trying to install npm react-facebook-login in my react app, but I keep getting dependency errors? That sounds scary and I don't want to force install something that can potentially break in the future. I'm new to javascript, what are some ways I should proceed?

I've tried clearing my npm cache and removing node modules and installing them again, however im still getting this error.

This error comes from version 7.x of npm. Please try again adding the --legacy-peer-deps option, as follows:

npm install react-facebook-login --legacy-peer-deps

Since npm install seems broked i tried:

yarn install

And it works!

Thanks

I started getting the error (below) after upgrading npm from version 6 to 7.

npm ERR! code ERESOLVE npm ERR! ERESOLVE unable to resolve dependency tree

...

npm ERR! Fix the upstream dependency conflict, or retry this command with --force, or --legacy-peer-deps to accept an incorrect (and potentially broken) dependency resolution.

In my case, using either --legacy-peer-deps or --force resulted in a useless bundle.

So I tried deleting the node_modules, package-lock.json, and bundle using yarn install. This generated a yarn.lock file and created a new package-lock.json that seemed to work fine in subsequent npm runs.

p.s. This is a temporary workaround until npm 7 works fine. After that, I will delete yarn.lock, package-lock.json and node_modules, and re-bundle using npm.

rm -rf node_modules
rm package-lock.json 
yarn install 
# generates a yarn.lock file and a new package-lock.json

# continue with npm 
npm start

Use this at the end --force, or --legacy-peer-deps

Eg:-

npm install --force

or

npm install --legacy-peer-deps

I face this challenge too, and I was trying to run my react.js application.

I have solved it by running: npm install --legacy-peer-deps

After It started as normal

@react-native-firebase/app@12.6.1
├── @react-native-firebase/auth@12.6.1
├── @react-native-firebase/firestore@12.7.1

Notice that firestore has a version of 12.7.1 and all other has 12.6.1, as firestore is a peer of other modules, to maintain consistency, it is also ought to be of the same version as it's peers, when that doesn't happens then you result in the error you have mentioned,

until the first number of the version doesn't changes, you can use --legacy-peer-deps and the result will be somewhat above [get the list of packages installed using npm ls --depth=0,

however if you want all of them to be of the same version, you can do the following

  • type npm update and all the packages will be updated to the latest version, the version will be mostly in which the second number changes. you can also use npm update with the specific package to only update the one you want to in order to resolve the error.

  • install the specific version of the module by npm install [package-name]@[version-number]

Simply adding --force help me to resolve this error.

yarn install --force
user_43933510

on the command, you are running just add on this --legacy-peer-deps

for me, the command was

npm install @reduxjs/toolkit react-redux

then I added

npm install @reduxjs/toolkit react-redux --legacy-peer-deps

and then boom it works

Try running

npm update

especially if the error is a result of a firebase package that may be having a version that is outdated thus conflicting with its peers. Solved my issue as suggested by @snehal

Maybe you are trying to install the packages into a wrong file path.

user_200392490

Try this code , and you should be fine:

npm install --save react-typical --legacy-peer-deps
