I’m having a dependency conflict when doing npm i in my React project.
This project was not started by me, but by an external company, and now it is my turn to modify the code with the tasks assigned to me.
The problem is that to update or install a package, I get several errors, forcing me to use npm i --force.

>Solution :
As you’re experiencing a conflict with peer dependencies in your project. The package amchart4-react is requiring a version of React that is either ^15.0.0 or ^16.0.0, while your project is using react@18.2.0. Here are a few ways you can attempt to resolve the conflict:
Update the amchart4-react Package (If Possible):
If there is a newer version of amchart4-react that supports React 18, you should update to that version. Check the package’s documentation or its entry in the npm registry to see if a newer version is available.
Downgrade React Version:
If you don’t need the specific features of React 18, you could downgrade to a version that satisfies both your project’s requirements and the requirements of amchart4-react. For example, you could try installing react@16.14.0, which seems to be the version that’s compatible with amchart4-react.
- npm install react@16.14.0 react-dom@16.14.0
Use –legacy-peer-deps:
You can try running the install command with the –legacy-peer-deps flag, which tells npm to ignore the peer dependencies and install the package anyway.
2 npm install –legacy-peer-deps
Consider Alternative Libraries:
If you’re unable to resolve the conflict by updating or downgrading packages, you might need to look for an alternative to amchart4-react that supports your current React version.
Manual Resolution (Not Recommended):
As a last resort, you could manually edit the package.json file of amchart4-react to change the peer dependency requirement. However, this is generally not recommended, as it can lead to unexpected behavior and makes your project harder to maintain.
Remember that resolving dependency conflicts can sometimes lead to other issues, particularly if other parts of your code rely on specific versions of the conflicting packages. Always thoroughly test your application after making changes to dependencies to ensure that everything continues to work as expected.
