Question

我目前正在尝试安装gem nfoiled，它为ncurses提供了一个ruby接口。我是在 README 中使用gem install elliottcable-nfoiled建议的。从github存储库手动下载然后用rake install安装它不起作用，因为echoe-gem存在问题，因此我必须使用正常方式。

不幸的是，它取决于仅与ruby 1.8兼容的gem ncurses-0.9.1，因此我也无法安装nfoiled（因为它总是首先尝试编译ncurses-0.9.1）：

novavortex:/usr/src# gem install elliottcable-nfoiled

make: *** [form_wrap.o] Error 1


Gem files will remain installed in /usr/local/lib/ruby/gems/1.9.1/gems/ncurses-0.9.1 for inspection.

我设法修复了ncurses-0.9.1中的问题（通过用RARRAY_LEN（x）替换RARRAY（x） - ＆gt; len）并安装它，但nfoiled仍然总是试图从新下载的源代码重新编译它

如何在不首先重新编译ncurses的情况下安装nfoiled？

Answer 1

你说你已经手动修复了ncurses。然后，您可以使用--ignore-dependencies开关安装另一个没有依赖关系的gem：

gem install elliottcable-nfoiled --ignore-dependencies

Answer 2

我能够在ruby 1.9.2-head下安装ncurses-ruby而没有任何问题，我无法安装nfoiled gem，因为它需要特定版本的echoe。


$ gem install --source http://gems.github.com elliottcable-nfoiled
ERROR:  Error installing elliottcable-nfoiled:

$ gem install ncurses

你确定你有正确的ncurses开发标题，以便构建ruby绑定吗？
