我在使用bootstrap时使用较少的客户端，但无法在没有错误的情况下解析它。
对于已经处理过的类和变量，我得到“错误NameError is undefined”消息。
我单独导入核心变量，重置，核心重置和我需要的所选组件：
<link href="less/variables.less" rel="stylesheet/less" type="text/css" />
<link href="less/mixins.less" rel="stylesheet/less" type="text/css" />
<link href="less/normalize.less" rel="stylesheet/less" type="text/css" />
<link href="less/print.less" rel="stylesheet/less" type="text/css" />
<link href="less/scaffolding.less" rel="stylesheet/less" type="text/css" />
<link href="less/type.less" rel="stylesheet/less" type="text/css" />
<link href="less/code.less" rel="stylesheet/less" type="text/css" />
<link href="less/grid.less" rel="stylesheet/less" type="text/css" />
<link href="less/tables.less" rel="stylesheet/less" type="text/css" />
<link href="less/forms.less" rel="stylesheet/less" type="text/css" />
<link href="less/buttons.less" rel="stylesheet/less" type="text/css" />
<link href="less/navbar.less" rel="stylesheet/less" type="text/css" />
<link href="less/navs.less" rel="stylesheet/less" type="text/css" />
<script type="text/javascript">
less = { env: 'development' };
</script>
<script src="js/less.js" type="text/javascript"></script>
解析所有较少的文件，但只生成前四个文件。其他人说：
NameError: .clearfix is undefined in navs.less on line 13, column 3:
NameError: variable @padding-base-vertical is undefined in buttons.less on line 20, column 16:
我可以看到.clearfix是在mixins.less中定义的，而@ padding-base-vertical是在variables.less中定义的，它们都被解析并生成而没有错误。
请告诉我一些错误！
