ios - 尝试使用 babel-plugin-proposal-class-properties 时使用 .babelrc 的语法加倍

问题描述

全部，

我试图在我的代码包中包含 babel-plugin-proposal-class-properties，但出现以下错误；

2020-01-07 08:19:31.593 [错误][tid:NSOperationQueue 0x2817acc40 (QOS: UNSPECIFIED)][RCTCxxBridge.mm:414] 加载包失败( http://169.254.99.36:8081/index.bundle? platform=ios&dev=true&minify=false ) 有错误:(index.js: 找不到模块 'babel-plugin-plugin-proposal-class-properties' from '/Users/bburch/Projects/systems/SystemsDockConfig' - 你的意思是“ @babel/plugin-proposal-class-properties"? (null))

我的 .babelrc 看起来像；

{   "presets": [
    "@babel/env",
    "@babel/react",   ],   "plugins": ["proposal-class-properties",] }

我也尝试过这种语法；

{
  "presets": [
    "@babel/preset-env",
    "@babel/preset-react"
  ],
  "plugins": ["@babel/plugin-proposal-class-properties"]
}

在任何一种情况下，包名称的“插件”部分都会以某种方式加倍，当然，发生这种情况时找不到模块。

我的 package.json;

{
  "name": "SystemsDockConfig",
  "version": "0.0.2",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "@babel/plugin-proposal-class-properties": "^7.7.4",

    "jest": "^24.9.0",
    "metro-react-native-babel-preset": "^0.56.0",

  },
  "jest": {
    "preset": "react-native"
  }
}

解决方案

我建议您将 .babelrc 更改为 babel.config.json 并使用{ 确保安装

npm i --save-dev @babel/plugin-proposal-class-properties

这应该可以工作 bable.config.json

{
    "presets": ["@babel/preset-env", "@babel/preset-react"],
        "plugins": [

            "@babel/plugin-proposal-class-properties"
        ]
}
