我试图创建我的第一个gem，这里是它的结构： │├──riverbattle ││├──base.rb ││├──colorful.rb ││├──computer.rb │ │├──constants.rb ││├──exit_error.rb ││├──field.rb ││├──game.rb ││├ ──human.rb ││├──invalid_move_error.rb ││├──move.rb ││├──player.rb ││├── version.rb ││└──victory_error.rb │└──riverbattle.rb └──riverbattle.gemspec
当我在 rivarbattle / lib / riverbattle 目录中运行命令 ruby base.rb ，一切都开始工作。
文件 base.rb 在这里：
require'./游戏' game = Game.new.start但是当我尝试从使用命令 ruby riverbattle.rb 的 lib 目录，它会失败并显示以下错误：
/home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54 ： require'：无法加载这个文件 - riverbattle / base （LoadError）from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ ruby / site_ruby / 2.2.0 / rubygems / core_ext / kernel_require.rb：54： require'from riverbattle.rb：1：in''$ b
文件 lib / riverbattle.rb 看起来像这样：
require'riverbattle / base'尽管负载失败我试图用以下.gemspec文件构建gem：
＃ - * - 编码：utf-8 - * - lib = File.expand_path（'../ lib'，__FILE__） $ LOAD_PATH.unshift（lib）除非$ LOAD_PATH.include？（lib）需要riverbattle /版本 Gem :: Specification.new do | s | s.name ='riverbattle' s.date ='2015-07-04' s.summary ='享受游戏！' s.description ='A小型简单游戏称为Riverbattle' s.platform = Gem :: Platform :: RUBY s.version ='0.1.0' s.authors = [Denis Yakovenko] s.email = [yakovenko.denis.a@gmail] s.require_paths = [lib] s.license =MIT end成功构建后，我去了irb并尝试了 require'riverbattle'并得到错误：
LoadError：无法加载此文件 - riverbattle

1）我在做什么错误 require ，来自不同目录的文件不能装？ （在查看stackoverflow问题后，我发现这是$ LOAD_PATH的问题，但我找不到如何修复代码。顺便说一句，需要 LoadErrors发生2）当我尝试使用 require_relative ，有时它会有帮助）
2）为了让irb中的宝石出现问题，由于 require 的最初问题引发错误，对吧？或者别的什么是错的？
$ b $ 3）如果我想将测试文件夹添加到gem，我可以添加文件夹 tests 到根目录并复制所有rspec文件？ 更新当我尝试运行 RUBYLIB =。 ruby riverbattle.rb 在终端中的 lib 文件夹中，它给了我：

解决方案
1。 #require 尝试加载绝对路径，如果失败，则从 $：加载到添加你的当前目录像这样运行脚本（bash，否则使用适当的方法为你的shell定义环境变量）：
RUBYLIB = ruby riverbattle.rb在您的 base.rb 要求如下：
要求'riverbattle / game'2。 请参阅#UPD部分
3。 为什么不呢？ （这是什么特定问题）
#UPD第二个问题是因为你错过 $ b $ b
s.files = Dir ['lib / *。rb'] + Dir ['lib / riverbattle / *。rb']＃UPD2
总结这里正在为您的宝石设置工作。
I'm trying to create my first gem and here's its structure:
riverbattle ├── lib │ ├── riverbattle │ │ ├── base.rb │ │ ├── colorful.rb │ │ ├── computer.rb │ │ ├── constants.rb │ │ ├── exit_error.rb │ │ ├── field.rb │ │ ├── game.rb │ │ ├── human.rb │ │ ├── invalid_move_error.rb │ │ ├── move.rb │ │ ├── player.rb │ │ ├── version.rb │ │ └── victory_error.rb │ └── riverbattle.rb └── riverbattle.gemspecWhen I am in the directory rivarbattle/lib/riverbattle and I run the command ruby base.rb, everything starts working as it should be.
The file base.rb is here:
require './game' game = Game.new.startBut when I try to run it from the lib directory using command ruby riverbattle.rb, it fails with the following error:
/home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require': cannot load such file -- riverbattle/base (LoadError) from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from riverbattle.rb:1:in `'
The file lib/riverbattle.rb look like this:
require 'riverbattle/base'Despite the fact that the load fails I tried to build the gem with the following .gemspec file:
# -*- encoding: utf-8 -*- lib = File.expand_path('../lib', __FILE__) $LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib) require "riverbattle/version" Gem::Specification.new do |s| s.name = 'riverbattle' s.date = '2015-07-04' s.summary = 'Enjoy the game!' s.description = 'A small simple game called the Riverbattle' s.platform = Gem::Platform::RUBY s.version = '0.1.0' s.authors = ["Denis Yakovenko"] s.email = ["yakovenko.denis.a@gmail"] s.require_paths = ["lib"] s.license = "MIT" endAfter the successful build, I went to irb and tried require 'riverbattle' and got the error:
LoadError: cannot load such file -- riverbattle
from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require' from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from (irb):1 from /home/denis/.rvm/rubies/ruby-2.2.1/bin/irb:11:in `'
1) What am I doing wrong with require that the files from different directories cannot be loaded? (After looking through stackoverflow questions I figured out that this is some problem with $LOAD_PATH, but I couldn't find out how to fix the code. BTW, such require LoadErrors happen quite often for some reason and then I try to use require_relative and sometimes it helps)
2) When I tried to lauch the gem in irb, the error was raised because of those initial problems with require, right? Or something else is wrong?
3) If I want to add tests folder to the gem, can I just add the folder tests to the root directory and copy all the rspec files there?
UPDATEWhen I tried to run RUBYLIB="." ruby riverbattle.rb in the terminal in the lib folder, it gave me this:
RUBYLIB="." ruby riverbattle.rb /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require': cannot load such file -- ./field (LoadError) from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from /home/denis/WEB/Bursa/riverbattle/lib/riverbattle/game.rb:1:in <top (required)>' from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require' from /home/denis/WEB/Bursa/riverbattle/lib/riverbattle/base.rb:1:in ' from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in require' from /home/denis/.rvm/rubies/ruby-2.2.1/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:inrequire' from riverbattle.rb:1:in `'
解决方案
1. #require tries to load an absolute path, and if it fails it loads from $:, to add your current directory run the script like this (bash, otherwise use apropriate method to define environment variables for your shell):
RUBYLIB="." ruby riverbattle.rbIn your base.rb require as follows:
require 'riverbattle/game'2. see #UPD section
3. why wouldn't you? (what's your specific problem with this?)
#UPDThe 2nd issue is because you miss #files in your gem specification, no files are included in your gem file, add something like this:
s.files = Dir['lib/*.rb'] + Dir['lib/riverbattle/*.rb']#UPD2
Just to summarize here is working setup for your gem.
