来自 UglifyJs SyntaxError 的 bundle.js 中的错误:意外标记:名称 (x) [英] ERROR in bundle.js from UglifyJs SyntaxError: Unexpected token: name (x)

问题描述

我的应用是用 Reactjs 制作的.

I have my app made with Reactjs.

当我尝试运行 npm run-script build 时，我得到了这个错误:

I'm gettint this error when I try to run npm run-script build:

ERROR in bundle.js from UglifyJs
SyntaxError: Unexpected token: name (x)  [./react/stores/UserStore.js:52,20]

ERROR in bundle.js from UglifyJs
SyntaxError: Unexpected token: name (x)  [./react/stores/UserStore.js:52,20]

错误被抛出两次.并注释了指向文件的行！现在我尝试不使用这些行，但仍然遇到相同的错误.但这是我第一次遇到这个错误，不知道为什么，而且我已经好几个星期没有碰过那个文件了...

The error is thrown twice. And the line of the file that is poiting is commented! And now I try without those lines and I'm still getting the same error. But this is the first time that I have this error, don't know why, and i haven't touched that file in weeks...

有什么想法吗?

推荐答案

好吧，就我而言，我没有 babel-preset-es2015 所以:

Well, in my case was that I didn't have babel-preset-es2015 so:

1. npm install --save-dev babel-preset-es2015
2. 在 webpack-production.config.js 中添加 es2015，像这样:['es2015', 'es2016', 'react']

Uglify 将使用 es6 代码(es6 -[babel preset es2015]-> es5 -> webpack with uglify plugin -> done)

The Uglify will work with es6 code (es6 -[babel preset es2015]-> es5 -> webpack with uglify plugin -> done)
