使用 Ruby gem 部署 shell 脚本并安装在 bin 目录中 [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，以及属于该包的其他 Ruby 程序.我希望将这个 shell 脚本按原样安装在 bin 目录中(即没有包装器).Ruby gem 有可能吗?如果不可能的话，我会对安装后的钩子感到满意.有人有这方面的经验吗?

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?

推荐答案

这里描述了这个问题:https://github.com/rubygems/rubygems/issues/88

如果您正在开发的 gem 仅供您自己使用，您可以简单地安装它

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

我认为您最好编写一个运行 bash 脚本的 ruby​​ 脚本.这是一个关于如何做到这一点的示例:

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}`

<小时>

bin/test_gem.sh

#!/bin/sh

echo "Hello World!"

<小时>

test_gem.gemspec

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

# ...

spec.executables = ['test_gem']

<小时>

注意:不要忘记将 bin 文件夹中的两个文件都设置为可执行！

---

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

请注意，虽然 test_gem.sh 已通过 files Rubygems 命令注册，但它并未注册为 executables:它只会被放置在已安装 gem 的目录，但未包装/填充.

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.

如果你安装了你的 gem(必要时运行 rbenv rehash)，调用 test_gem 将导致 ruby​​ 脚本执行你的 shell 脚本.

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