今天在buntu10.10使用源码安装完ruby1.9.2p290和rubygem1.8.10后,想利用gem去安装rails: gem install rails,结果提示 no such file to load -- zlib 错误。
zlib is a library implementing the deflate compression method found
in gzip and PKZIP.
解决办法,安装zlib1g 和 zlib1g-dev 包(apt-get install 或者利用Synaptic),然后
1.回到ruby源码目录/ext/zlib 下
2. ruby extconf.rb
3. make && make install
问题解决。
