将红宝石宝石从一台机器转移到另一台机器的最佳实践 [英] best practices for transfering ruby gems collection from one machine to another

问题描述

我想将所有的宝石从一台机器（foo）复制到另一台机器（棒）。两台机器都是相同的，只是foo有一堆安装的宝石，而且bar没有（bar不能上网）。

我从foo复制/ usr / local / lib / ruby​​ / gems到bar，现在bar会识别安装的宝石。

  root @ bar＃gem list 
 
 ***本地GEMS *** 
 
 keybox（1.2.1）
 rake（0.9.2.2）
 ...等等
  

如果我尝试从原生位置运行它们，它们按预期工作

  root @ bar＃cd /usr/local/lib/ruby/gems/1.8/gems/keybox-1.2.1/bin 
 root @ bar＃./keybox --version 
 keybox：version 1.2.1 
  

我想将所有宝石放在一个共同的bin目录下，就像他们在foo上一样

  root @ bar＃find /usr/local/lib/ruby/gems/1.8/gems/*/bin -type f | xargs -I baz ln -s baz / usr / local / bin / 
  

如预期的那样，这会创建符号从每个宝石的位置到/ usr / local / bin / $ /

对于一些宝石（如rake）的链接一切都按预期工作，对于其他人（如keybox），它不起作用。对于一些宝石来说，gem dir中的脚本和/ usr / local / bin下的脚本是有区别的。

  root @ foo＃diff /usr/local/lib/ruby/gems/1.8/gems/keybox-1.2.1/ bin / keybox / usr / local / bin / keybox

因为我已经复制从一台机器到另一台机器的宝石，我也可以很容易地复制公共脚本，但是有没有更多的宝石方式来做到这一点？是否有一个gem命令会重新生成公开脚本，就像在keybox中显然已经完成的那样？

以下命令：

  gem pristine --all 
  

这将重新从缓存源（我相信你已经复制）重新安装了gems，因此应该重新创建脚本包装器，重新编译扩展等。

您也可以查看文档来调整命令以适合您的需要（有一个标志只是恢复可执行文件，如果这就是你想做的）。

i want to copy all of my gems from one machine (foo) to another (bar). both machines are identical except that foo has a bunch of gems installed and bar does not (bar cannot get onto the internet).

i copied /usr/local/lib/ruby/gems from foo to bar, and now bar recognizes that the gems are installed.

root@bar # gem list

*** LOCAL GEMS ***

keybox (1.2.1)
rake (0.9.2.2)
... and so on

if i try to run them from their native location, they work as expected

root@bar # cd /usr/local/lib/ruby/gems/1.8/gems/keybox-1.2.1/bin
root@bar # ./keybox --version
keybox: version 1.2.1

i would like to have all gems under a common bin dir, like they are on foo

root@bar # find /usr/local/lib/ruby/gems/1.8/gems/*/bin -type f | xargs -I baz ln -s baz /usr/local/bin/ 

as expected, this creates symbolic links from each gem's location to /usr/local/bin/

for some gems (like rake) everything works as expected, for others (like keybox) it does not work. for some gems, there's a difference between the script in the gem dir and the one that gets installed under /usr/local/bin.

root@foo # diff /usr/local/lib/ruby/gems/1.8/gems/keybox-1.2.1/bin/keybox /usr/local/bin/keybox

since i'm already copying gems from one machine to another i could just as easily copy the public scripts as well, but is there a more "gemish" way to do it? is there a gem command that will regenerate the public scripts as has apparently been done in the case of keybox?

解决方案

Try using the following command:

gem pristine --all

That will reinstall the gems from the cached source (which I believe you copied), and therefore should recreate script wrappers, recompile extensions, etc.

You can also check the documentation to adjust the command to suit your needs (there's a flag to just restore the executables, if that's all you want to do).
