node.js - ionic 框架 : Ionic build fails while creating the project (v4. 12.0)

Question

我的系统中安装了 ionic。当我运行 ionic run app tabs 时，它会安装所有的 npm 包，但随后提示符变为

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.11.0/linux-x64-72_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.11.0/linux-x64-72_binding.node":

HTTP error 404 Not Found

然后失败并显示提示

我已经尝试删除 node_modules 并重新安装包。我也尝试重新安装 ionic-cli。哪个不起作用。

我正在使用 Node v12.0.0npm v6.9.0ionic v4.12.0

确实，版本 https://github.com/sass/node-sass/releases/download/v4.11.0/linux-x64-72_binding.node 不可用，因为您正在使用 Node v12 并尝试为 Node v12 获取不受支持的 node-sass 版本。

解决方案是将您的 Node 版本降级到 v11 或将您的 node-sass 依赖项升级到最新版本。

如果您(对于与另一个库有相同问题的访问者。这里是 ionic)正在使用 node-sass 作为供应商库，请降级到 node v11 并通知库开发团队需要更新。
