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

遇到这个问题，npm i @ionic/app-scripts是唯一工作的东西。

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

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:)

更新你的sass-loader应该会有神奇的效果。

npm i sass-loader@latest

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
