应用解决方案：

1. 已安装的nodejs 7.3.0（截至目前的当前版本）。

注意：我曾尝试安装x64位，但由于我遇到错误，所以我切换到x86版本但仍然没有运气。我也尝试将nodejs降级到6.9.2和v4.4.7，但没有取得任何进展。

Note: I have tried to install x64 bit but since I got errors, so I switched to x86 version and still no luck. I have also tried to downgrade nodejs to 6.9.2 and v4.4.7 but have made no progress at all.

1. 使用npm install -g npm升级npm，清除缓存并更新注册表

1. Upgraded npm using "npm install -g npm", clear cache and update registry

尝试重建node-sass

Tried to rebuild node-sass

尝试手动安装minimatch，uuid和fsevents

Tried to install minimatch, uuid and fsevents manually

任何想法，我在安装过程中错过了什么？在使用离子版本1创建项目时遇到了同样的问题。

Any idea, what I missed during the installation? I got same problems when creating projects using ionic version 1.

推荐答案

在一系列卸载和安装所有依赖项后，我发现了由于node-sass与当前版本的nodejs不兼容而导致问题发生。我通过以下方式解决了这个问题：

After series of uninstalling and installing the all dependencies, I found out that the problem occurred because of the incompatibility of node-sass to the current version of nodejs. I have solved the problem by:

1. 安装x86 nodejs版本7.3.0


2. 安装cordova和离子（非beta）


3. 更新了node-sassinstall -g node-sass


4. 使用命令npm再次构建node-sass rebuild node-sass

1. installing x86 nodejs version 7.3.0
2. install cordova and ionic (not beta)
3. updated node-sass "install -g node-sass"
4. built node-sass again by using the command "npm rebuild node-sass"

之后，当我尝试运行ionic serve命令时，发生了错误。错误消息是：

After that, the when I tried to run "ionic serve" command, an error occurred. The error message was:

离子服务错误：错误：ENOENT：没有这样的文件或目录，打开
'/ home /.../ IonicTest / www / index.html'

"Ionic serve error: Error: ENOENT: no such file or directory, open '/home/.../IonicTest/www/index.html'"

1. run命令npm run build参考：

1. run the command "npm run build" reference:

欢呼！它已经在工作：D

And cheers! It's already working :D
