Titanium 更新钛时出错

我已经在ubuntu 12.10中安装了钛。但是，当我尝试安装Tianium CLI、Node.ACS和Alloy的更新时，我收到了以下错误：

Failed to get value of npm config key prefix: npm ERR! Error: EACCES, mkdir '/home/ralf/Titanium_Studio/[sudo] password for ralf: /home/ralf/Titanium_Studio/[sudo] password for ralf: /home/ralf/Titanium_Studio/[sudo] password for ralf: /home/ralf/Titanium_Studio'

这是什么意思？如何解决此问题？

通过命令行中的此命令运行Tianium studio应用程序

sudo ./TitaniumStudio

---

而不是单击文件夹中的文件

您是否以root用户身份运行该命令？（前缀为

sudo

）？不，当我运行Tianium时，它总是要求我更新。没有使用命令行界面。但它在开始安装之前会询问我的密码。等等，我已经解决了我的问题。谢谢@Sukima。
