无法在VM内的Ubuntu中使用npm安装less

我在安装less时遇到了这个错误。我使用此代码

npm安装-g less

，但它显示了这种错误：

编辑：

我根据答案安装了node的更新版本。我现在有这个提示。这是一个错误吗？谢谢

我的Ubuntu版本是12.04。请帮忙，我需要它尽快为我的项目。谢谢：）

尝试更新节点的版本

npm ERR! Required: ["node >= 0.8.0"]
Actual: {"npm":"1.1.4","node":"0.6.12"}

有关说明，请参见此处：

尝试将npm/节点升级到最新版本，然后重试

谢谢，我升级了我的节点版本。看起来我以前的节点版本是0.6.12，现在我安装了v0.12.2。但是现在我在“sudo npm安装-g less”中遇到了困难，我使用了

sudo npm-v less

，它显示了我的版本。它已成功安装。谢谢：DYup，那个输出在我看来或多或少是正确的。它看起来像是来自于less的可选依赖项，根据它们的属性。不过，很高兴听到你把事情解决了！
