安装节点-sass目录时，离子教程失败

Question

我正试图通过运行以下命令(如详细的在他们的文档中的教程页面上 )在我的系统上运行Ionic教程：

sudo ionic start MyIonicProject tutorial

但是，当教程试图在MyIonicProject中构建节点-sass目录时总是失败的：

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

当它试图在node-sass/build目录中构建时，权限被拒绝--但是我如何对一个还不存在的目录设置权限呢？以前的错误在调用mkdir时输出以下内容：

Error: EACCES: permission denied, mkdir '/Users/imacuser/MyIonicProject/node_modules/node-sass/vendor'

父目录具有读/写权限。我在网上看到这个问题有不同的变化，但我找不到任何明确的答案。当您无法运行主教程时，很难学习框架。感谢你能在这里给新人的任何帮助。

编辑:在将读/写权限应用于所有封闭项之后，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意义的，因为node-sass目录是在运行时创建的，如果没有自动读取/写入权限，如果它们不存在，就很难添加它们。

Answer 1

首先，您需要为用户和组分配权限。

1. 选择磁盘、文件夹或文件，然后选择file > Get Info。
2. 单击锁定图标解锁，然后输入管理员名称和密码。
3. 在Name列中单击某个用户或组，然后从弹出菜单中选择一个特权设置，并给予读写权限。
4. 单击“动作”弹出菜单(Crog )，然后选择“应用于封闭项”。

在向目录应用权限之后，请在项目目录中运行此命令。

sudo npm rebuild node-sass --force

它将强制重建项目目录中的节点-sass。
