如果你使用NVM, VS Code和VS Code任务资源管理器来运行使用node-sass的npm脚本,下面的警告将为你节省一些时间。

I was using VS Code's Task Explorer to run my scripts and have installed multiple Node versions using NVM, defaulting to the current latest version 16. When I opened my VS Code repository and ran nvm use 10 in a new terminal, the Node and npm version in that terminal window correctly downgrades, but the version of node/npm used by the Task Explorer runner remained at Node 16. So when running my webpack script using the VS Code Task Runner, node-sass would still throw the environment error of this question.

解决方案是不使用VS Code任务运行器,在你改变节点版本的终端上运行你的脚本,或者使用下面的命令改变默认的NVM节点版本,重新启动VS Code,然后使用任务资源管理器/运行器。

NVM别名默认10(或任何你需要node-sass兼容性的版本)

回滚到节点v10.17.0解决了我的问题。

你可以使用nvm来这样做:

https://github.com/nvm-sh/nvm

> nvm install 10.17.0
> nvm use 10.17.0
> node -v
10.17.0

我尝试了这个,但它不适合我,并抛出错误:

npm --depth 9999 update 
npm rebuild node-sass

我已经安装了最新的Node.js(目前是11.11.0 Current),在遇到这个问题后,我只是做了以下工作:

降级到推荐版本(目前是10.15.3 LTS) 你可以从NodeJS中获取, 删除node_modules和 然后重新安装纱线:

     yarn install
     yarn start

在执行这些命令之后,一切都运行正常。

试试这个:

npm --depth 9999 update
npm rebuild node-sass

查看Node - Sass发布说明,了解您拥有的Node - Sass版本,了解需要哪个版本的Node。如果node的版本错误,则必须降级node或升级node-sass,直到有兼容的对为止。如果节点版本被支持,你可能只需要运行npm rebuild node-sass。如果这不起作用,你可以npm卸载node-sass或npm安装node-sass

我得到这个错误时,我更新节点使用NVM。 去掉这条线; NPM重建node-sass
