如何解決自定義組件庫中react多副本的問題

Question

我有兩個項目，第一個是主應用，第二個是自定義組件庫，都在react中。 主應用程序通過npm link命令使用自定義組件庫。

但是，在主應用程序中使用自定義組件庫中的自定義鈎子違反了鈎子規則，因為有 2 個不同的反應實例。 為了解決這個問題，我將react和react-dom移到了自定義組件庫的 package.json 中的peerDependencies中， peerDependencies在自定義組件庫的peerDependencies中添加了以下幾行。

module.exports = {
...
externals: {
        'react': {
            commonjs: 'react',
            commonjs2: 'react'
        },
        'react-dom': {
            commonjs: 'react-dom',
            commonjs2: 'react-dom'
        }
    }
...
}

最后，我刪除了 node_modules 並在自定義組件庫中再次運行npm i 。 但是，我無法構建庫，它給出了以下錯誤構建階段。

ERROR in ./src/index.tsx 1:0-48 
Module not found: Error: Can't resolve 'react/jsx-runtime' in 'path\to\src'

我在這個配置中缺少什么？

注意：我的自定義組件庫中還有 app.tsx 和 index.tsx。

自定義組件庫的 webpack.config.js

module.exports = {

                }

            },
        ]
    },
    resolve: {
        extensions: ['.tsx', '.ts', '.js']
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: path.join(__dirname, "public", "index.html"),

Answer 1

cd node_modules/react-dom
yarn link 
cd .. 
cd node_modules/react
yarn link 

在本地，您可以為 react 和 react-dom 鏈接應用程序的節點模塊，因此它只使用一個版本。
