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)

这里的最佳解决方案是迁移到dart-sass,因为node-sass库已被弃用。

删除node_modules并运行npm install为我修复了这些错误。

其他人说:npm重建node-sass或npm审计修复可能会有帮助。

NPM卸载node-sass && NPM安装node-sass是更好的解决方法

命令npm uninstall node-sass && npm install node-sass对我没有帮助,但在安装Python 2.7和Visual c++构建工具后,我删除了node_modules文件夹,从管理员打开CMD并运行npm install——msvs_version=2015。安装成功!

这条评论和这个链接也会有所帮助。

如果你有一个用节点8构建的旧项目,你必须在节点8下运行:

$npm rebuild node-sass

然后切换到10号或以上节点,执行以下命令:

$npm uninstall node-sass && npm install node-sass

在这些行动之后,我一切都很好。如果我在节点8或节点10或更高的节点下执行此操作,则不会修复项目中的问题。 也许它会帮助别人:)
