：錯誤紅寶石：不能加載這樣的文件 - 當我嘗試在Ubuntu 12.10安裝導軌我得到這個錯誤的zlib
$ gem install rails
ERROR: Loading command: install (LoadError)
cannot load such file -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
所以我完全去除RVM：
rvm implode
sudo rm -rf ~/.rvm
刪除腳本在我.bashrc和.bash_profile
要求和檢查，如果他們真的刪除：
env | grep rvm #no output, so rvm is removed
ruby -v #The program 'ruby' can be found in the following packages: blabla
我通過sudo已經有這些的apt-get安裝：
curl zlib1g-dev zlib1g libssl-dev build-essential openssl libreadline6 libreadline6-dev curl git-core libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config
然後繼續從頭開始安裝
curl -L https://get.rvm.io | bash -s stable --ruby --auto-dotfiles
然後運行該行並重新啓動終端對於這個消息：
* To start using RVM you need to run `source /home/adige/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
Then rvm pkg install readline但完成時出現錯誤：
...
Error running 'autoreconf -is --force', please read /home/adige/.rvm/log/readline/autoreconf.log
...
Please note that it's required to reinstall all rubies:
rvm reinstall all --force
我認爲它是反正安裝的吧？之前重新安裝所有的紅寶石，我安裝了當然的zlib：
# w/out verify, it gives checksum error
rvm pkg install zlib --verify-downloads 1
然後運行rvm reinstall all --force，並再次完成時發生錯誤：
...
Install of ruby-1.9.3-p374 - #complete
Making gemset ruby-1.9.3-p374 pristine.
Error running '' under ,
please read /home/adige/.rvm/log/ruby-1.9.3-p374/gemset.pristine.log
Making gemset [email protected] pristine.
然後重新安裝紅寶石支持zlib：
rvm reinstall 1.9.3-p374 --with-zlib-dir=$rvm_path/usr
哪些返回了相同的錯誤和無論如何都完成了。
最後我試着再次安裝rails gem，但是cannot load such file -- zlib！
這裏是rvm info
我在做什麼錯？
