npm i There is a certain dependency version conflict when downloading dependencies
An error occurred when downloading npm i dependency, probably the version problem
npm ERR! code ERESOLVE

Solution
Add --legacy-peer-deps after npm install to solve it
npm i --legacy-peer-deps
In fact, the meaning of this command itself is to let it ignore the conflicts caused by dependencies when downloading dependencies (this is my personal understanding!)

solve:
- When downloading npm
- --legacy-peer-deps
- In NPM v7, peerDependencies is now installed by default.
In many cases, npm version issues can lead to download conflicts, which interrupts the installation process.
The --legacy-peer-deps flag was introduced in v7, with the purpose of bypassing peerDependency automatic installation;
It tells NPM to ignore the problems of the same modules but different versions between the modules introduced in the project and continue to install them, ensuring that the different versions of modules used by each introduced dependencies coexist on itself.

The above is personal experience. I hope you can give you a reference and I hope you can support me more.
