ubuntu安装rails 出现异常
ubuntu安装rails 出现错误
安装mysql:
按顺序执行 肯定不出错
1: sudo apt-get install mysql-server mysql-client libmysqlclient15-dev
2: sudo gem install mysql
这段时间把centos换成ubuntu后，环境重装，在装rails时出现了以下错误：
请注意如果使用RVM安装的Ruby，安装文件在Src文件中，而不是在Rubies文件中。
afeicool@localhost:~$ gem install rails ERROR: Loading command: install (LoadError) no such file to load -- zlib ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand
解决方案：
apt-get install zlib-bin zlib1g-dev cd path/to/your ruby source dir/ext/zlib ruby extconf.rb –with-zlib-include=/usr/include –with-zlib-lib=/usr/lib make make install
