我真的可以在这方面使用某人的帮助，因为我已经解决这个问题很长时间了，而且没有任何补救措施。
问题只是将 NativeScript CLI 安装到我的 OSX Yosemite Mac 上。我按照 NS 网站的步骤进行操作（安装正确的 Node.JS 版本，下载 Xcode 7.2（由于操作系统限制），安装 JSDK，安装 NS Sidekick，安装带有正确 SDK 的 Android Studio 以及所有其他所需的依赖项。
但是，当我运行“sudo npm i -g nativescript --unsafe-perm”（否则它会引发 EACCES 错误）时，我会收到以下日志，上面写着我错过了我知道我拥有的所有这些依赖项，但它声称我不。
最大的问题是，虽然它仍然会说 NativeScript 已成功安装，但每当我运行任何 tns 命令（如 tns doctor）时，都找不到 bash 命令。
我已确保遵循将 NS 添加到我的路径以及我的 Android 和 Java SDK 的指示。这是完整的日志：

我能做些什么来解决这个问题？每次我在卸载它后尝试重新安装时，npm 也会声明“rollbackFailedOptional”。npm 是否缓存了损坏的版本，我可以强制它进行真正的“重新安装”吗？一切看起来都一团糟，我真的不想放弃 NS，这太令人沮丧了。让我知道你的想法，谢谢！
