用Ruby gem部署一个shell脚本并安装在bin目录下 [英] Deploy a shell script with Ruby gem and install in bin directory

问题描述

我希望在我的gem的bin目录中放置一个shell脚本，以及属于这个包的其他Ruby程序。我希望这个shell脚本按原样安装在bin目录中（也就是没有包装）。这对Ruby宝石来说可能吗？如果没有其他可能，我会很满意后安装钩子。任何人都有这方面的经验吗？

解决方案

这个问题在这里描述：
https://github.com/rubygems/rubygems/issues/88

如果您正在开发的宝石仅用于您自己的用途，您可以简单地将它安装在

  gem install --no-wrapper my_gem 
  

我认为您最好编写一个运行您的bash脚本的ruby脚本。下面是一个例子：

---

bin / test_gem

 ＃！/ usr / bin / env ruby​​ 
 $ b bin_dir = File.expand_path（File.dirname（__ FILE__））
 shell_script_path = File.join（bin_dir，'test_gem.sh'）
 
`＃{shell_script_path}`
  

---

bin / test_gem.sh

 ＃！/ bin / sh 
 
 echoHello World！ 
  

---

test_gem.gemspec

  spec.files = [
＃... 
'bin / test_gem'，'bin / test_gem.sh'
] 
 
＃... 
 
 spec.executables = ['test_gem'] 
  

---

注意：不要忘记将<$ c

请注意，尽管 test_gem.sh 是注册到文件 Rubygems命令，它没有注册为可执行文件：它只会被放置在已安装的gem的目录中，但如果你安装了gem（并且如果需要的话运行rbenv rehash），调用 test_gem 将不会被包装/填充。 导致ruby脚本执行你的shell脚本。

I wish to place a shell script in my gem's bin dir, along with other Ruby programs that belong to the package. I wish to have this shell script installed in the bin directory as-is (that is, no wrappers). Is that possible with Ruby gems at all? I would be happy with post-install hooks if not otherwise possible. Anybody has any experience with this?

解决方案

This issue is described here: https://github.com/rubygems/rubygems/issues/88

If the gem you're developing is intended only for your own use, you can simply install it with

gem install --no-wrapper my_gem

I think you'd best write a ruby script which runs your bash script. Here's an example on how to do that:

---

bin/test_gem

#!/usr/bin/env ruby

bin_dir = File.expand_path(File.dirname(__FILE__))
shell_script_path = File.join(bin_dir, 'test_gem.sh')

`#{shell_script_path}`

---

bin/test_gem.sh

#!/bin/sh

echo "Hello World!"

---

test_gem.gemspec

spec.files = [
  # ...
  'bin/test_gem', 'bin/test_gem.sh'
]

# ...

spec.executables = ['test_gem']

---

NOTE: Don't forget to set both files in the bin folder to executable!

Note that while test_gem.sh is registered with the files Rubygems command, it's not registered as executables: it will just be placed in the installed gem's dir but not wrapped/shimmed.

If you install your gem (and run rbenv rehash if necessary), calling test_gem will result in the ruby script executing your shell script.
