Ruby qtbindings ubuntu安装错误

我尝试在我的新虚拟机上安装gem。我按照gem页面上的说明做了所有的事情，但是有些地方出了问题。我有安装错误：

vagrant@machine:~$ sudo gem install qtbindings
Building native extensions.  This could take a while...
ERROR:  Error installing qtbindings:

乌布努16.04。我做错了什么

已解决

安装cmake和qt-sdk

---

请注意，如果您通过RVM使用多个Ruby版本，您需要确保已安装并选择了2.2.6。要检查已安装的版本，请运行

rvm list

如果没有安装Ruby 2.2.6，则需要通过运行

rvm install 2.2.6

rvm get stable --auto-dotfiles

要选择2.2.6，请运行

rvm use 2.2.6

如果是新安装，您还需要在路径中添加2.2.6 gems。通过跑步来做到这一点

rvm install 2.2.6

rvm get stable --auto-dotfiles

---

我相信关于qtbindings github的说明非常简单

在linux/MacOSX上，您必须确保安装了所有必要的先决条件，否则编译将失败。

此外，错误日志指出

cmake:not found

。您能否先尝试安装

cmake

，然后运行

gem安装qtbindings

？让我知道这是否解决了问题谢谢你的帮助。安装cmake，然后安装qt-sdk。它解决了我的问题。与qt sdk相比，可以安装数量较少的软件包，并且具有所有依赖项。
