ionic-framework - 安装 node-sass 目录时 Ionic 教程失败
问题描述
我正在尝试通过运行以下命令在我的系统上运行 Ionic 教程（详见他们的文档中的教程页面：
sudo ionic start MyIonicProject tutorial
但是，本教程在尝试在 MyIonicProject 中构建 node-sass 目录时总是失败：

当它尝试在node-sass/build目录中构建时，权限被拒绝 - 但是如何在尚不存在的目录上设置权限？调用 mkdir 时，较早的错误会输出以下内容：
Error: EACCES: permission denied, mkdir '/Users/imacuser/MyIonicProject/node_modules/node-sass/vendor'
父目录确实具有读/写权限。我在网上看到这个问题有不同的变体，但我找不到任何明确的答案。当您无法运行主要教程时，很难学习框架。感谢您可以在此处为新手提供的任何帮助。
编辑：在对所有随附项目应用读/写权限后，添加@ZearaeZ 建议的两个命令的完整结果。构建仍然失败：
MacBook-Pro-6:~ macdad$ sudo npm rebuild node-sass --force
npm WARN using --force I sure hope you know what you are doing.
MacBook-Pro-6:~ macdad$ sudo ionic start MyIonicProject
? ./MyIonicProject exists. Overwrite? Yes
Let's pick the perfect starter template!
Starter templates are ready-to-go Ionic apps that come packed with everything
you need to build your app. To bypass this prompt next time, supply template,
the second argument to ionic start.
? Starter template: tabs
✔ Preparing directory ./MyIonicProject - done!
✔ Downloading and extracting tabs starter - done!
? Integrate your new app with Cordova to target native iOS and Android? Yes
> ionic integrations enable cordova --quiet
✔ Downloading integration cordova - done!
✔ Copying integrations files to project - done!
[OK] Integration cordova added!
Installing dependencies may take several minutes.

正如我所建议的那样，我不能对该目录拥有权限是有道理的，因为该node-sass目录是在运行时创建的，如果它没有自动读/写权限，那么如果它们不存在就很难添加它们.
解决方案
首先，您需要为用户和组分配权限。
选择磁盘、文件夹或文件，然后选取“文件”>“显示简介”。
单击锁定图标将其解锁，然后输入管理员名称和密码。
点按“名称”栏中的用户或群组，然后从弹出式菜单中选取权限设置并授予读取和写入权限。
单击“操作”弹出菜单（Crog 图标），然后选择“应用于封闭项目”。</p>
向您的目录应用权限后在您的项目目录中运行此命令。
sudo npm rebuild node-sass --force
它将在您的项目目录中强制重建 node-sass。
