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

其他回答

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

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

需要将节点降级至14版本:

npm install -g n
n 14
# if one of the commands does not pass, you may need to use sudo
sudo npm install -g n
sudo n 14
