Why a dependency would not want to install when installing a library?-CodePudding

I'm new at at creating node modules.

I'm currently building a component library for a React-native app.

It works fine when a component does not rely on a third-party library but when it does, it seems like installing the library does not install the dependencies.

Here's a simple example:

package.json from the component library :

"dependencies": {
"lottie-ios": "3.2.3",
"lottie-react-native": "^5.1.3"

Then I tried to add it as peerDependencies but it didn't solve the issue :

    "peerDependencies": {
    "react": "*",
    "react-native": "*",
    "lottie-ios": "3.2.3",
    "lottie-react-native": "^5.1.3"
  },

(Since then I removed it from the peerDependencies).

Back to the RN project I want to implement, when installing the component library, lottie does not install.

Am I missing something here ?

CodePudding user response：

There's an issue with the dependencies used by your dependencies. Your react version is not compatible (according to npm) with the react version used by one of your dependencies. Thus conflicting in a peer dependency conflict. This is an issue if you're using npm version > 6.

You can resolve by passing the --legacy-peer-deps flag when running npm install. Resulting in: npm i --legacy-peer-deps
