以上这些方法对我都没用。我完全删除，然后重新安装，它解决了这个问题。

删除现有的:

npm uninstall --save-dev node-sass 

然后重新安装:

npm install --save-dev node-sass

我用angular 7得到了这个错误，帮助我的是， 从windows power shell运行命令:

npm install --global --production windows-build-tools

然后我再次打开我的VS Code，在它的终端上运行相同的命令 NPM卸载node-sass并安装node-sass

如果上述答案没有解决您的问题，请尝试一次

npm uninstall node-sass
npm install node-sass@4.14.1

来源:这里

当使用Visual Studio中的任务运行器资源管理器时，确保你优先选择正确的PATH。

还要确保，一旦你改变优先级，重新启动VS。

$(PATH)指向默认节点路径 .\node_modules\.bin指向本地项目路径

因此，当您使用NVM切换节点版本时，您应该选择系统路径。

以上解决方案都不工作，因为我在用npm rebuild node-sass或重新安装或卸载/安装重建node-sass时遇到了错误。

解决方案是将GCC (g++)版本升级到最新的7.3.1，而不是我之前安装的4.8.5。

旧的4.8.5不支持命令行选项'-std=c++14'，该选项在安装时编译node-sass时使用。

所以只要升级gcc，然后使用任何解决方案与节点重建node-sass或任何其他上面提到的。

我把npm从6.4.12升级到7.14.0，这个错误消失了。然后我得到了另一个错误

错误:节点Sass版本5.0.0与^4.0.0不兼容。

我在这里找到了解决办法。我卸载了node sass 5.0.0并安装了4.14.1(显然这是node sass的最新4个版本，使用npm view node-sass versions命令进行了验证)。

这给了我一卡车的错误。 NPM安装node-sass@

然后我尝试了npm审计fix -force

就会得到这个错误

npm WARN audit No fix available for cp-cli@*
npm ERR! code ETARGET
npm ERR! notarget No matching version found for object-path@1.1.5.
npm ERR! notarget In most cases you or one of your dependencies are requesting

我检查了我的包裹。Json中有object-path: "0.11.4"

然后我尝试了npm install node-sass@4.0.0

在Ubuntu 20.04上，这个问题基本上陷入了地狱。我不应该升级到Ubuntu 20.04。

我会继续努力，并在这里报告我的发现。我有信心解决这个问题。

编辑 我将npm从7.14.0降级到6.14.12,npm start现在报告错误:Node Sass版本6.0.0与^4.0.0不兼容。我检查了npm node_sass -v报告6.14.12。我运行npm uninstall node-sass和npm install node-sass@4.14.1。

立即编辑工作 我遵循了这里的步骤，然后

节点-v -> 16.something

NVM install lts/erbium ->设置节点为12.22.1

NPM卸载node-sass

NPM安装node-sass@4.14.0

这个方法奏效了
