Gulp js错误通知未显示错误来源

Question

一切都已设置并正在连接和编译我的样式和脚本。当 gulp-notify 和 gulp-plumber 发生错误时，将错误作为 mac 通知和终端抛出，并且 gulp 不会停止运行 - 这很棒:)

但是，我发现终端中抛出的脚本错误始终是编译文件 script-dist.js 的问题，而不是实际连接的源文件。

错误

gulp-notify: [JS Error] _PATH_/js/script-dist.js: Unexpected token keyword «var», expected punc «{»
Error in plugin 'gulp-uglify'
Message:
    _PATH_/js/script-dist.js: Unexpected token keyword «var», expected punc «{»
Details:
    fileName: _PATH_/js/script-dist.js
    lineNumber: 3

请注意，这并没有告诉我实际错误来自哪里（应该说它在 _modal.js 中，这是我故意在其中创建错误的串联文件之一。

你 concat 在传递给 uglify 之前，就 Uglify 而言，那里只有一个文件。您可能想使用例如一个 linter 首先传递文件，确保它们是正确的。

或者，使用sourcemaps，可以利用哪些工具来显示发生错误的原始文件。
