使用gulp / webpack并使用spread运算符获得意外的令牌错误

Question

我已经安装了stage-2，我发现它应该让这个工作。但是，当我构建项目时，它无法正常工作。我将添加我的：

.babelrc
webpack.config.js
gulpfile.js
package.json

让你看看我在做什么。文件将按顺序排列。

{
  "presets": ["es2015", "react", "stage-3", "stage-0", "stage-1", "stage-2", "env"],

堆栈跟踪显示它在Gulp中是一个错误，因为Webpack部分没有显示错误。问题是你正在使用

var to5 = require('gulp-6to5');

这根本不是巴别塔，但巴贝尔的旧版本称为“6to5”。如果您将其更改为使用gulp-babel并安装它，那么事情应该有效。

根据您发布的配置，您可以将内容减少到

{
  "presets": ["env", "react", "stage-0"]
}

并使用该配置，您也可以删除

query: {
  presets: ['react', 'es2015', 'env', 'stage-2']
}

来自您的Webpack配置，因为它已经在.babelrc。

如果对象休息/传播是您计划使用的唯一实验性功能，您也可以

{
  "presets": ["env", "react"],
  "plugins": ["transform-object-rest-spread"]
}
