Ruby-on-rails 在 zlib 上安装 Ubuntu rails 失败

Ubuntu rails install fails on zlib

提问by Paul

I've just moved over to Ubuntu 8.10 as my dev box; it's my first serious foray into Linux as a daily-use OS, and I'm having a hard time getting Rails going. I have followed a number of tutorials which all seem to work fine, but when I try and use gem install or gem update on anything, I get an error that looks like this:

我刚刚转移到 Ubuntu 8.10 作为我的开发箱；这是我第一次认真地尝试将 Linux 作为日常使用的操作系统，而且我很难让 Rails 运行起来。我遵循了许多似乎都可以正常工作的教程，但是当我尝试在任何东西上使用 gem install 或 gem update 时，我收到一个如下所示的错误：

/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- zlib (LoadError)

from /usr/local/bin/gem:21

I have (as recommended in the tutorials) installed zlib, zlib1g, and zlib1g-dev. I've even found a few tutorials on this particular problem (all for flavors other than mine, however) but they didn't help.

我已经（按照教程中的建议）安装了 zlib、zlib1g 和 zlib1g-dev。我什至找到了一些关于这个特定问题的教程（然而，所有这些都适用于我以外的其他口味），但它们没有帮助。

I'm on Ubuntu 8.10, ruby version 1.8.8dev gem version 1.3.2

我在 Ubuntu 8.10，ruby 版本 1.8.8dev gem 版本 1.3.2

I've tried reinstalling ruby and gems each and separately, to no avail.

我试过分别重新安装 ruby​​ 和 gems，但无济于事。

If you come across this question trying to install Ruby using Ruby Version Manager (RVM) on Ubuntu 10.04 then there are instructions on installing zlib on the rvm web site http://rvm.beginrescueend.com/packages/zlib/

如果您在 Ubuntu 10.04 上尝试使用 Ruby 版本管理器 (RVM) 安装 Ruby 时遇到这个问题，那么 rvm 网站上有关于安装 zlib 的说明http://rvm.beginrescueend.com/packages/zlib/

The steps are:

步骤是：

rvm pkg install zlib

(or rvm package install zlibif you get "ERROR: Unrecognized command line argument: 'pkg'" - older versions of rvm used the verb 'package' instead)

（或者，rvm package install zlib如果您收到“错误：无法识别的命令行参数：'pkg'” - 较旧版本的 rvm 使用动词 'package' 代替）

then

然后

rvm remove 1.9.1
rvm install 1.9.1

I am using Ubuntu 10.04 (Lucid), i wanted to install ruby 1.9.2 because 1.9.1 is not recommended with Rails. So I downloaded the source for 1.9.2 and unzipped/unarchived it. my source distro is ruby-1.9.2-p0. After I unpacked it, I built zlib as follows:

我使用的是 Ubuntu 10.04 (Lucid)，我想安装 ruby​​ 1.9.2，因为 Rails 不推荐 1.9.1。所以我下载了 1.9.2 的源代码并解压/解压了它。我的源发行版是 ruby​​-1.9.2-p0。解压后，我构建了zlib，如下所示：

cd ruby-1.9.2-p0/ext/zlib
ruby extconf.rb
make
sudo make install
sudo gem install rails

that fixed the problem. This is similar to what other people posted above, but not exactly, so I figured I may as well post exactly what I did to get it going.

解决了这个问题。这与上面其他人发布的内容类似，但不完全相同，所以我想我最好发布一下我为让它运行所做的工作。

I have the same problem in CentOS and fix it by executing the following command:

我在 CentOS 中遇到了同样的问题，并通过执行以下命令来修复它：

First, I ensure that zlib and zlib-devel exist (like many suggested above).

首先，我确保 zlib 和 zlib-devel 存在（就像上面建议的许多）。

yum install zlib zlib-devel

Second, I recompiled and installed the sources of zlib that comes with ruby.

其次，我重新编译安装了ruby自带的zlib源码。

cd /home/myname/installers/ruby-1.8.7-p174/ext/zlib/
ruby extconf.rb --with-zlib-include=/usr/include --with-zlib-lib=/usr/lib
make
make install

That commands seem to fix the problem, then I execute gem update --systemand the error with zlib vanished. Then I install rails with gem install rails. Note to mention I had installed gem before, and after recompile and install zlib, I don't recompile neither install gem (actually I don't knew how uninstall it because I don't found a script to do that)

该命令似乎解决了问题，然后我执行gem update --system了 zlib 的错误消失了。然后我用 gem install rails 安装 rails。请注意，我之前安装了 gem，重新编译并安装 zlib 后，我没有重新编译 install gem（实际上我不知道如何卸载它，因为我没有找到执行此操作的脚本）

That works for me...hope to you to.

这对我有用...希望你能。

问候。

try

尝试

aptitude install zlib1g-dev

Then go about your business.

然后去处理你的事情。

Just goto Ruby Source Package , Unzip it.

只需转到 Ruby Source Package ，解压它。

Goto /your-ruby-dir/ext/zlib

转到 /your-ruby-dir/ext/zlib

ruby extconf.rb
make
sudo make install

If the packages are missing it will tell you, mainly libzlib related packages

如果包丢失它会告诉你，主要是libzlib相关的包

rvm package install zlib
rvm remove 1.9.1
rvm install 1.9.1

That did it. After numerous wild goose chases, I'm glad I found this page.

做到了。经过无数次的追逐，我很高兴找到了这个页面。

回答by Paul

yes, and that didn't do the job either. Got this from another source, this finally did it for me where the other stuff failed.

是的，这也不起作用。从另一个来源得到这个，这终于为我做了其他事情失败的地方。

wget http://www.blue.sky.or.jp/atelier/ruby/ruby-zlib-0.6.0.tar.gz
tar xvzf ruby-zlib-0.6.0.tar.gz
cd ruby-zlib-0.6.0
ruby extconf.rb && make
sudo make install

Reinstall ruby gems from source

从源重新安装 ruby​​ gems

Thanks anyway, guys.

无论如何，谢谢，伙计们。

Did you try apt-get install libzlib-ruby?

你试过 apt-get install libzlib-ruby 吗？

Also install rubygems from rubyforge. I don't like the rubygems package in Ubuntu.

还要从 ruby​​forge 安装 ruby​​gems。我不喜欢 Ubuntu 中的 ruby​​gems 包。

The problem is that Ruby on Ubuntu isn't built against zlib; you'll want to do a source build to install Ruby. You can do this with apt-get source -b ruby

问题是 Ubuntu 上的 Ruby 不是针对 zlib 构建的。您需要进行源代码构建以安装 Ruby。你可以这样做apt-get source -b ruby
