搭建 react native 开发环境

M1 无法使用 pod install

sudo gem install cocoapods
sudo arch -x86_64 gem install ffi
cd ios
arch -x86_64 pod install

IOS 开发注意事项

1. 安装依赖后需要链接

推荐使用以下命令链接:

yarn pod
#  即 npx pod-install ios

或者 M1 使用以下命令链接:

cd ios
arch -x86_64 pod install

其他使用以下命令链接：

cd ios
pod install

配置项目 alias

安装 babel-plugin-module-resolver 插件

yarn add --dev babel-plugin-module-resolver

配置 .babelrc

{
  "presets": ["module:metro-react-native-babel-preset"],
  "plugins": [
    ["module-resolver", {
      "root": ["./src"],
      "alias": {
        '@/utils': './src/utils',
        '@/pages': './src/pages',
        '@/components': './src/components',
      }
    }]
  ]
}

配置 tsconfig.json

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/utils/*": ["./src/utils/*"],
      "@/styles/*": ["./src/styles/*"],
      "@/actions/*": ["./src/actions/*"],
      "@/components/*": ["./src/components/*"],
      "@/services/*": ["./src/services/*"],
    }
  }
}

IOS 与 Android 调试

启动模拟器

yarn ios
yarn android
