Question

我正在尝试通过运行以下命令（详细说明at their Tutorial page in their docs来在系统上运行Ionic教程：

sudo ionic start MyIonicProject tutorial

但是，当本教程试图在MyIonicProject中构建node-sass目录时，该教程始终会失败：

gyp verb build dir attempting to create "build" dir: /Users/macdad/MyIonicProject/node_modules/node-sass/build

尝试在node-sass/build目录中构建权限时被拒绝-但是如何在尚不存在的目录上设置权限？调用mkdir时，先前的错误输出以下内容：

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的变化形式不同，但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。感谢您可以在此处提供新手的任何帮助。

编辑：将@ZearaeZ建议的两个命令的完整结果添加到所有包含的项上具有读/写权限之后。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.

根据我的建议，我没有该目录的权限是有道理的，因为node-sass目录是在运行时创建的，并且如果该目录没有自动的读/写权限，则很难如果不存在，请添加它们。

Answer 1

首先，您需要为用户和组分配权限。

选择磁盘，文件夹或文件，然后选择“文件”>“获取信息”。
单击锁定图标将其解锁，然后输入管理员名称和密码。
在“名称”列中单击一个用户或组，然后选择一个特权从弹出菜单中进行设置，并赋予“读写”权限。
单击“操作”弹出菜单（“青蛙”图标），然后选择“应用于封闭的项目。”

对目录应用权限后，在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。
