gem 无法安装 bropages

有一款替代手册页文档软件，名为 bropages，用 ruby​​ 编写，我想安装它。我按照网站，但出现以下错误：

~$ sudo gem install bropages
Building native extensions.  This could take a while...
ERROR:  Error installing bropages:

我对 Ruby 宝石并不熟悉，而且我没有看到任何明确指出错误的东西。那么这里出了什么问题？我该如何安装 bropages？

我尝试过sudo apt-get install bro但那完全是另一回事。

答案1

您可能缺少编译模块时所需的 ruby​​ 头文件。

如果你使用的是 Debian/Ubuntu，请使用以下命令安装它们：

sudo apt-get install ruby-dev

然后再次尝试安装 bropages。

答案2

你可能缺少编译此 gem 所需的本机依赖项所需的一些文件

尝试运行以下命令

sudo apt-get update
sudo apt-get install ruby2.1-dev

此后，尝试再次安装 bropages gem，看看错误是否消失或改变

答案3

就我而言，我需要安装依赖项。

来自文档：

sudo apt-get install cmake make gcc g++ flex bison libpcap-dev libssl-dev python-dev swig zlib1g-dev
