SASS编译不起作用

Question

我正在使用Visual Studio 2013和Web Essentials 2013 update4。并嵌入了SASS。但是突然sass文件停止编译新的代码到css所有导入的文件都在工作（在包含mixins时有问题）但是当我添加包含sass代码的新文件并将其导入主sass文件时它无法工作和编译，甚至我直接在主sass文件中添加了代码。以下是主sass文件中的代码：

@import "Common/_public.scss";
@import "HomePage/_video.scss";
@import "HomePage/_home.scss";
@import "HomePage/_control.scss";
@import "HomePage/_monitor.scss";
@import "HomePage/_analyze.scss";
@import "HomePage/_accesibility.scss";
@import "HomePage/_capability.scss";
@import "HomePage/_portability.scss";
@import "HomePage/_contact-us.scss";
@import "HomePage/_footer.scss";
@import "Exrill/_exrill-side-menu.scss";
@import "Exrill/_home.scss";
@import "Exrill/_added-value.scss";
@import "Exrill/_dashboard.scss";
@import "Exrill/_pob.scss";
@import "Exrill/_footer.scss";
@import "Common/_animation.scss";
@import "More/_more-public.scss";
@import "More/_about-us.scss";
@import "More/_portfolio.scss";
@import "More/_job-opportunity.scss";
@import "Common/_font.scss";

.pricing-body{
    width:100%;
    margin:0 auto;
}

.pricing-list {
    width: 800px;
}

.pricing-list table {
    width: 100%;
}

所有导入的文件现在都在运行，但纯css代码没有!!!
