我目前正在创建一个组件库,该组件库通过NPM链接包含在Nextjs项目中,并且很难使其始终如一地加载而不会出错。最新的是
无效的挂钩调用。挂钩只能在功能组件的主体内部调用。发生这种情况可能是由于以下原因之一
这是一个Typescript组件,但据我所知,我所做的一切还可以,但是它不是在玩运动。这是代码:
import React, { useEffect } from "react";
import { FlagIcon } from "react-flag-kit";
const LanguageSwitcher = () => {
useEffect(() => {
alert('Yo!');
})
return (
<div className="w-full justify-end">
<button>
<div className="flex items-center">
<FlagIcon code="GB" /> <span className="block ml-2">English</span>
</div>
</button>
</div>
)
}
export default LanguageSwitcher
然后将其导入库中的另一个组件,然后导入Nextjs页面。错误出现在哪里。
我不确定这是Webpack还是打字稿编译问题,尝试过我能想到的所有不同目标,尝试过搜索各种事物,但似乎与我的情况无关。甚至可能不是React问题,而是Typescript和Webpack的问题,但是我对这些问题的了解非常新。
我的webpack配置:
var path = require('path');
module.exports = {
entry: './src/index.ts',
devtool: "source-map",
output: {
path: path.resolve(__dirname, 'build'),
filename: 'index.js',
libraryTarget: 'commonjs2'
},
module: {
rules: [
{
test: /\.ts(x?)$/,
use: 'ts-loader',
exclude: /node_modules/,
},
{
enforce: "pre",
test: /\.js$/,
loader: "source-map-loader"
}
]
},
resolve: {
extensions: [ '.tsx', '.ts', '.js' ],
}
};
我的tsconfig.json
{
"compilerOptions": {
"outDir": "build",
"module": "esnext",
"target": "es6",
"lib": ["es6", "dom", "es2016", "es2017"],
"sourceMap": true,
"allowJs": false,
"jsx": "react",
"declaration": true,
"moduleResolution": "node",

"suppressImplicitAnyIndexErrors": true,
"noUnusedLocals": true,
"noUnusedParameters": true,
"allowSyntheticDefaultImports": true
},
"include": ["src"],
"exclude": ["node_modules", "build"]
}
任何指针或帮助将不胜感激!
我还尝试将所有内容恢复为原始JS,问题仍然存在,所以我认为这可能与webpack有关?
修改
这是我完整的package.json文件,还有Nextjs所拥有的

答案 0 :(得分:0)
原来这是由于组件库中的符号链接反应问题
https://reactjs.org/warnings/invalid-hook-call-warning.html#duplicate-react
通过运行链接中的步骤修复:
npm link ../myapp/node_modules/react // Run within the component library

面临同样的问题。但是,组件库不归我所有,因此不得不使用此 dependency resolution by 'Yarn'
这是我最初的依赖树
project
|- componentLibrary
| |- react@16.10
| |- react-dom@16.10
|- react@17.0.1
|- react-dom@17.0.1
在我的 package.json 中添加了以下代码片段
"resolutions": {
"componentLibrary/react": "17.0.1",
"componentLibrary/react-dom": "17.0.1"
},
解决了我对项目 react
和 react-dom
的依赖。
