Kev*_*gem 5 transpiler reactjs babeljs parceljs
我似乎无法让 Babel 与 Parcel 一起工作,尽管预设是自动安装的。它可以在本地和 Chrome 中运行,但它不会转译 node_modules es6 文件,因此输出仍然存在const/let/...并且无法在 Safari 中运行。
.babelrc
{
"presets": ["@babel/preset-env","@babel/preset-react"]

(我也试过env和react那些)。
package.json 脚本
"scripts": {
"start": "parcel index.html",
"build": "parcel build index.html",

为什么会这样?
完整的 package.json (注意这是为了让它工作而搞砸之后)

仍然获取带有const, 的.js 文件let。任何想法我缺少什么?
我从https://github.com/parcel-bundler/parcel/issues/1655#issuecomment-425593377找到了解决方案
// .browserslistrc.packages
node 10.11
// package.json
{
"scripts": {
"postinstall": "npm-run-all -p \"postinstall:*\"",
"postinstall:p-retry": "cpy --rename=.browserslistrc .browserslistrc.packages node_modules/p-retry",
"postinstall:query-string": "cpy --rename=.browserslistrc .browserslistrc.packages node_modules/query-string"
}

postinstall:package-name为每个需要添加转译的 npm 包添加一个(在我的例子中为pinyin)并npm run postinstall在每个npm install. Babel 现在还应该转译该 npm 包!
