我正在尝试用grunt（Ubuntu 14.04）构建AngularJS项目，但是在运行它时，100％的CPU吃得非常慢。
这是我的grunfile

grunt.loadNpmTasks('grunt-contrib-copy');

grunt.loadNpmTasks('grunt-karma');

我已经使用了一段时间没有任何问题，一切都很好！它已经突然开始了，我尝试了几件事来提升它而没有任何结果。我认为它与grunt本身没有关联，但更多的是我正在使用的系统（在其他操作系统上它很好）。有什么问题？
更新
重新安装grunt-contrib-uglify后，一切似乎都没问题。考虑到要编译的模块的数量，仍然uglify任务需要一分钟才能完成，但这或多或少都很好。

您可以使用time-grunt输出有关导致问题的任务的数据。然后，您可以集中精力优化该特定任务。

我很想更新所有软件包。我在grunt-ts团队工作，我们有文件随机看着我们100％的cpu都有karma使用的手表库和grunt-watch使用的那个
答案 2 :(得分：0)
如果您有许多grunt模块，那么jit-grunt可能有所帮助。它只加载您正在运行的任务所需的grunt模块，而不是每次都尝试加载每个模块。
您可以在此处查看load-grunt-config的实现：

在interval中添加options：
options: {
interval: 5007,
nospawn: true,
livereload: true
}
