Gem构建"目标'的配方'stemmer.so'失败了"

Question

从gem使用安装Jekyll时gem install jekyll,我收到以下构建错误.我在Windows 7上使用Cygwin,并posix-spawn在安装之前从源代码构建了gem.

Building native extensions.  This could take a while...
ERROR:  Error installing jekyll-1.1.2.gem:

Gem files will remain installed in /usr/lib/ruby/gems/1.9.1/gems/fast-stemmer-1.0.2 for inspection.
Results logged to /usr/lib/ruby/gems/1.9.1/gems/fast-stemmer-1.0.2/ext/gem_make.out

我使用gem v2.0.7,ruby v1.9.3p448,gcc v4.8.1和g++ v4.8.1

有任何想法吗？我不知道什么时候涉及Ruby宝石.我找不到关于这个"限制器"的任何信息.

Answer 1

原来这个错误的症结在于cannot find -lcrypt.我安装libcrypt-devel后,宝石编译好了.

我认为在大多数原生Linux发行版中,这个库已经包含在内了!
