清理板岩安装Rails [英] Clean slate install Rails

问题描述

父亲，我做得很糟糕.我完全搞砸了我的系统. 当我尝试使Rails使用与MAMP PRO相同的MySQL时，一切都开始了. (我仍然没有设法让他们一起工作.)结局很糟，而且还在不断恶化.

Father, I've done terrible things. I've messed my system up completely. It all started back when I tried to make Rails to use the same MySQL that my MAMP PRO uses. ( I still haven't managed them to work together).It ended badly, and just keeps getting worse.

所以我决定，我应该只是清除RVM和Rails安装的系统，然后以一种正确的方式重新安装所有内容(目前，我已经尝试了不同的方法，包括将Rails gem作为sudo安装，不使用sudo并使用RVM).所有这些都是非常混乱的，我不知道我是怎么把它拉下来(把所有东西弄乱了的).

So I have decided, that I should probably just wipe the system clean of my RVM and Rails installations and then re-install everything in a single proper way (currently I've experimented with different approaches, including installing rails gem as sudo, without sudo, and with RVM). This all mess is very confusing, and I have no idea how did I even pull it off (to mess everything up).

无论如何-有人可以告诉我如何对所有宝石进行干净的擦拭，这样我的系统上就不会有任何痕迹，因此我可以执行干净的安装. 另外，在Mac OS X Lion上安装滑轨的最佳方法是什么.如果我只打算使用最新版本的Ruby和Rails，我应该还是不应该使用RVM?

Anyhow - can someone please tell me how to do a clean wipe on all gems, so there wouldn't be any trace of rails on my system, so I can perform a clean install. Also, what would be best way to install rails on Mac OS X Lion. Should or shouldn't I use RVM, if I am intending only to use the latest version of Ruby and Rails ?

如果我使用rvm，我不想只是忘记系统中的gems，因为偶尔不小心使用sudo时，我偶尔会遇到问题.我认为最好只有一个，就是这样.

I don't want to just forget about the gems in my system if I were to use rvm, as once in a while I run into problems when accidentally using sudo or not. I think it is best just have one and that's it.

干杯.

推荐答案

这里有一篇文章介绍了如何删除所有宝石，但请注意！

然后，这是一组命令，用于在没有RVM的情况下执行ruby 1.9.3和rails 3.2的全新安装:

Then, here are a set of commands to perform a clean install of ruby 1.9.3 and rails 3.2 without RVM:

curl ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p0.tar.gz -o ruby-1.9.3-p0.tar.gz
tar xvf ruby-1.9.3-p0.tar.gz
cd ruby-1.9.3-p0/
autoconf
./configure --program-suffix=19 --enable-shared --with-readline-dir=/usr/local
make && sudo make install

然后从此处下载最新的rubygems: http://rubyforge.org/frs/download.php/75711/rubygems-1.8.15.tgz

Then download the latest rubygems from here: http://rubyforge.org/frs/download.php/75711/rubygems-1.8.15.tgz

tar xvf rubygems-1.8.15.tgz
cd rubygems-1.8.15
sudo ruby setup.rb

最后安装导轨

sudo gem install rails
