ruby源码编译安装

Ruby源码编译安装

从ruby官网上下载ruby源码，https://www.ruby-lang.org/en/downloads/，解压：

./configure

make

make install

问题一：zlib

ERROR:  Loading command: install (LoadError)

    cannot load such file -- zlib
ERROR:  While executing gem ... (NameError)

    uninitialized constant Gem::Commands::InstallCommand

解决方法：

sudo apt-get install zlib1g-dev

进入ruby源码文件夹，

cd ext/zlib

ruby extconf.rb

make && make install

问题二：openssl

gem install bundle

error：Error: while executing gem (Gem::Exception)
  Unable to require openssl. install openSSL and rebuilt ruby (preferred) or use non HTTPs sources

解决方法：

（一）去掉加密：（不推荐）

gem source -r https://rubygems.org/ to remove

followed by

gem source -a http://rubygems.org/ to read

（二）重新编译：

重新编译ruby，可参考：http://stackoverflow.com/questions/28924827/unable-to-compile-ruby-with-openssl

cd etc/openssl




修改Makefile 否则编译失败

加入top_srcdir = ../..

然后

./configure

make && make install

最后到 源码目录下重新编译即可
