***安装muby泥客户端时*** extconf.rb失败***错误

Question

我对ubuntu没有经验 - 我在Ubuntu 13.04上尝试安装muby（http://rubyforge.org/projects/muby/）。 当我下载并试图安装宝石时...这是我得到的错误：

如果有人可以请告诉我如何解决这个问题 - 我已经广泛搜索谷歌并安装了很多东西（比如mysql，ruby版本和-dev的......没有尝试过RVM，因为我不知道怎么做）。< / p>

更新安装libncurses5-dev后，出现此错误：

Answer 1

错误信息非常明确：

checking for ncurses.h... no
...
...
...: ncurses hearder file not found

您只需要安装ncurses开发包：

apt-get install libncurses5-dev

更新这是ncurses gem中的一个错误，它没有更新为使用Ruby 1.9+，切换到Ruby 1.8.7，如果可以的话，它将构建为no错误。不幸的是，这颗宝石似乎不再是人造的。

您可以使用rvm或rbenv轻松安装Ruby 1.8.7，我建议使用后者。
