问题描述
Safari 无法使用此行加载我的 React 应用程序:
Safari is failing to load my React app with this line:
Const declarations are not supported in strict mode.
当我看到失败的线路时:
When I look at the line that's failing I'm seeing:
const Crypto = __webpack_require__(624)
这不是我的应用程序中的内容，因此必须由 Webpack 或其他依赖项注入.
This isn't something in my app so it must be injected by Webpack or another dependency.
Babel 不应该用 var 替换 const 吗?
Shouldn't Babel replace const with var?
It's not included in "es2015" preset. There you have only "check-es2015-constants" plugin which just checks and validates const declarations.
将 consts 转换为 vars 的插件称为transform-es2015-block-scoping"，它包含在es2015"预设中.
The plugin which transforms consts into vars is called "transform-es2015-block-scoping" and it's included in "es2015" preset.
