RN0.53开发常见问题

1 react-native 初始化项目后运行run-ios，报错

Error: Problem validating fields in app.json. See https://docs.expo.io/versions/v25.0.0/guides/configuration.html.
21:42:43:  • Field: slug - 'slug' should match pattern "^[a-zA-Z0-9\-]+$".

解决办法：
修改app.json,说明slug必须符合正则匹配：^[a-zA-Z0-9-]+$，即由大小写和“-”组成

{
  "expo": {
    "name": "zzcuti_rn",
    "slug": "zzcuti-rn",
    "sdkVersion": "25.0.0",
    "privacy": "public"
  }
}
