找不到要导入的文件或不可读的文件：〜bootstrap / scss / bootstrap

Question

当我尝试将SCSS编译为CSS时，出现此错误：

public IEnumrable<string> GetData(ref IEnumrable<string> data)
{
      return data.Where(c=> !String.Equals(c,"<<data that you want to filter>>");  
}

引导文件实际上位于node_modules文件夹中，并且导入也应正常进行：

/usr/local/bin/scss --no-cache --update app.scss:app.css
  error app.scss (Line 9: File to import not found or unreadable: ~bootstrap/scss/bootstrap.)

Process finished with exit code 1
