Babel CLI非常慢 [英] Babel CLI is extremely slow

问题描述

所以我遵循此处的安装方法，但是babel编译时间很长，甚至小文件:

So I follow the installation here, but babel takes very long time to compile, even small files:

app.js

let app = 1;

.babelrc

{ "presets": ["es2015"] }

package.json

"scripts": {
    "build": "babel app.js -o dist/app.js"
},
"devDependencies": {
    "babel-cli": "^6.4.5",
    "babel-preset-es2015": "^6.3.13"
}

然后npm run build大约需要30秒才能编译.

Then npm run build will take ~30s to compile.

我正在使用npm@3.3.12

推荐答案

您可能也在编译node_modules和bower_components.

您可以尝试在项目.babelrc中添加ignore属性，如下所示:

You can try adding the ignore property in your projects .babelrc like so:

{
  ...
  "ignore": /(node_modules|bower_components)/
  ...
}

希望这可以解决您的问题

Hope this solves your issue
