问题描述

我正在尝试通过运行 npm install node-sass@3.7.0 来安装 node-sass v3.7.0。安装似乎开始工作，然后我反复得到这个转储：

我多次在上面转储。最后返回这个消息：

+ node-sass@3.7.0
added 21 packages from 43 contributors and audited 2105 packages in 121.004s`

好像已经安装好了。但是当我尝试使用我的应用程序时，我收到 node-sass 错误，并且 npm list -g node-sass 表示该软件包未安装。它返回：

npm info it worked if it ends with ok
npm info using npm@6.4.1
npm info using node@v8.15.0
/Users/wvn179/.nvm/versions/node/v8.15.0/lib

这是什么问题？如何成功安装 node-sass？

解决方法

node-sass 有点过时了，我建议你改用 sass / sass-loader

npm install sass sass-loader
,

node-sass 3.7 已经很老了，它支持的最后一个 Node 版本是 7 https://github.com/sass/node-sass/releases/tag/v3.7.0，这也是生命周期的终结。

我有一个类似的问题，我通过使用节点版本管理器降级节点解决了这个问题？ https://gist.github.com/chranderson/b0a02781c232f170db634b40c97ff455
