Ruby(2.1.5p273) Rails (4.18) 在 Heroku 应用程序上部署错误 inflections.rb:1:in `require': cannot load such file -- thread _safe
Ruby(2.1.5p273) on Rails (4.18) deploying on Heroku Application error inflections.rb:1:in `require': cannot load such file -- thread _safe
我是RoR的完全菜鸟，这是我第一次使用Ruby做网站开发，结果证明是相当具有挑战性的...第一次学习的变量数量是……有点过分。我试了 4 天才弄清楚 RoR 的正确设置，但是，似乎我总是遇到障碍。
无论如何，这是我目前遇到的问题..我正在使用 windows 7 with ruby version 2.1.5p273 and rails version 4.18
我打算将我的应用程序部署到 Heroku，所以我首先使用命令创建 rails 应用程序：
rails new myapp --database=postgresql
之后我检查了 gemfile
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.8'
# Use jdbcpostgresql as the database for Active Record
gem 'activerecord-jdbcpostgresql-adapter'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.3'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
gem 'therubyrhino'
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc
# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'
# Use unicorn as the app server
# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development
# to solve tzinfo-data problem
gem 'tzinfo-data'
之后我用 git
存储应用程序
git init
git add .
git commit -m "initial commit"
然后进入localhost:3000，页面显示ruby默认页面，说明本地正在工作只是发现，
但是，当我尝试将应用程序推送到 heroku 时出现问题。
我遵循这个命令：
heroku create
git push heroku master
heroku open
原来是出了点问题，页面显示"Application error"页
浏览了一段时间后，我发现了 heroku 日志功能并试图找出问题所在，我无法清楚地理解日志，
这是日志：
Your version of git is 1.8.4.. Which has serious security vulnerabilities.

浏览了一段时间后，我发现使用以下命令可以更清楚地查找问题：
heroku run rails console
结果如下：
Your version of git is 1.8.4.. Which has serious security vulnerabilities.

现在它说了一些关于 inflections.rb:1:in 'require cannot load such file -- thread_safe(Load Error)
不确定这意味着什么，但在那之后我尝试做一些这样的事情：
1. 安装 thread_safe gems -> 没有改变
2. 安装 activesuport gems -> 没有改变
3. 我尝试将 ruby 版本更改回 2.0.0，但它说 'activerecord-jdbcpostgresql-adapter' 需要 jruby .
请直言 在这一点上，我对 ruby、jruby 和 postgresql 仍然知之甚少。由于我的知识有限，我对可能导致这个问题的可能原因的数量感到震惊。
所以，如果有人能指出正确的方向，我将不胜感激！
在与@elithrar 的评论中进行了一些讨论后，我开始寻找为什么涉及 jruby 的答案，
原来这里有一个很长的初始安装ruby，系统文件路径（可以在这里访问edit syst path for windows）
结果指向 jruby\bin，因此我将系统路径更改为另一个 ruby 版本（我从铁路网站下载）。只有在检查 ruby -v 是否正确后，我才 运行 bundle install .
这就解决了上面提到的所有问题，
gemfile \bin 不再指向 jruby.exe ，postgresql 的 gemfile 不再显示 activerecord-jdbcpostgresql-adapter 而是显示 gem "pg"
有一点问题但是当尝试做 bundle install 时，它告诉我 Your Ruby version is 2.1.5, but your Gemfile specified 2.0.0 只需编辑 gemfile，其中 ruby "2.0.0" 到 ruby "2.1.5" 修复了它
之后，按照教程 运行 顺利安装 ruby 并推送到 heroku
我的建议：
遇到同样问题的，请尝试查看系统路径中ruby的版本。它是否指向正确的目的地？

# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

gem 'tzinfo-data'
之后我用 git
存储应用程序git init
git add .
git commit -m "initial commit"
然后进入localhost:3000，页面显示ruby默认页面，说明本地正在工作只是发现， 但是，当我尝试将应用程序推送到 heroku 时出现问题。
我遵循这个命令：
heroku create
git push heroku master
heroku open
原来是出了点问题，页面显示"Application error"页 浏览了一段时间后，我发现了 heroku 日志功能并试图找出问题所在，我无法清楚地理解日志， 这是日志：
Your version of git is 1.8.4.. Which has serious security vulnerabilities.

浏览了一段时间后，我发现使用以下命令可以更清楚地查找问题：
heroku run rails console
结果如下：
Your version of git is 1.8.4.. Which has serious security vulnerabilities.

现在它说了一些关于 inflections.rb:1:in 'require cannot load such file -- thread_safe(Load Error)
不确定这意味着什么，但在那之后我尝试做一些这样的事情： 1. 安装 thread_safe gems -> 没有改变 2. 安装 activesuport gems -> 没有改变 3. 我尝试将 ruby 版本更改回 2.0.0，但它说 'activerecord-jdbcpostgresql-adapter' 需要 jruby .
请直言 在这一点上，我对 ruby、jruby 和 postgresql 仍然知之甚少。由于我的知识有限，我对可能导致这个问题的可能原因的数量感到震惊。 所以，如果有人能指出正确的方向，我将不胜感激！
在与@elithrar 的评论中进行了一些讨论后，我开始寻找为什么涉及 jruby 的答案，
原来这里有一个很长的初始安装ruby，系统文件路径（可以在这里访问edit syst path for windows）
结果指向 jruby\bin，因此我将系统路径更改为另一个 ruby 版本（我从铁路网站下载）。只有在检查 ruby -v 是否正确后，我才 运行 bundle install .
这就解决了上面提到的所有问题，
gemfile \bin 不再指向 jruby.exe ，postgresql 的 gemfile 不再显示 activerecord-jdbcpostgresql-adapter 而是显示 gem "pg"
有一点问题但是当尝试做 bundle install 时，它告诉我 Your Ruby version is 2.1.5, but your Gemfile specified 2.0.0 只需编辑 gemfile，其中 ruby "2.0.0" 到 ruby "2.1.5" 修复了它
之后，按照教程 运行 顺利安装 ruby 并推送到 heroku
我的建议：
遇到同样问题的，请尝试查看系统路径中ruby的版本。它是否指向正确的目的地？
