sah*_*hil 6 ruby mysql macos ruby-on-rails-3
从过去的两周开始，我一直在尝试在Mac上设置我的代码。以前，我使用Ubuntu，所以设置代码从未如此困难。我遵循了几乎所有教程，但没有运气。请任何人指导我在Mac上设置RoR。遵循所有教程之后，我最终只会遇到mysql错误。

在Ubuntu中用于设置Rails的步骤如下：
Installation of rvm and ruby in 12.04(Followed the link)
https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm
the steps are:
sudo apt-get update
sudo apt-get install curl
\curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm requirements(error will occur - not to worry. Go to the link provided to install the package-----)
rvm autolibs rvm_pkg
again give -> rvm requirements
rvm install 1.9.3
rvm use 1.9.3
get the code and do inside it
bundle install
later check with rails s.. if not working. do as follows
gem uninstall -i /home/user_xyz/.rvm/gems/ruby-1.9.3-p448@global bundler
then install
gem install bundler -v1.0.22
install git
sudo apt-get install git
then
bundle install --system
then again do
bundle install
If the bundle install --system is not working
gem install bundler --pre
again give
bundle install --system
It will ask to install the mysql2
install the mysql2
sudo apt-get install mysql2 -v0.3.13
again give
bundle install --system
then install the following for the mysql error
sudo apt-get install libmysql-ruby libmysqlclient-dev
After the mysql error. nokogiri error occurs
sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri
finally give
bundle install --system
install netbeans
first install java package
sudo apt-get install openjdk-7-jdk
sh netbeans-7.0.1-ml-linux.sh
Proceed as follows(Due to erros do the following)
gem uninstall bundler
bundle install
rvm @global do gem uninstall bundler
gem update bundle
bundle install --system
Error for event machine(Check the link: http://stackoverflow.com/questions/4735303/failed-to-install-gem-install-eventmachine-i-need-starling-in-my-project-fo)
sudo apt-get install build-essential
install event machine
gem install eventmachine -v '1.0.3'
bundle install --system
install mysql
sudo apt-get install mysql-server
change the password in the config/database.yml for the mysql
解决方案： 按照以下步骤设置Rails：
使用brew：安装了MySQL mysql Ver 14.14 Distrib 5.7.9, for
osx10.11 (x86_64) using EditLine wrapper。遵循mysql安装后在屏幕上给出的命令。
通过以下步骤安装了rvm：
\curl -L https://get.rvm.io | bash -s stable —ruby
rvm install 1.9.3
rvm use 1.9.3
rvm --default 1.9.3
安装的滑轨，gem install rails当前版本为'4.2.5'。
（mysql2 gem版本（0.3.20）可以通过Rails 4.1.4正常运行）
（mysql2 gem版本（0.4.2）和rails 4.2.5一起工作）
（mysql2 gem版本（0.3.20）用rails 3.2.14唤醒）
因此，现在我可以创建并运行新的Rails应用程序，但是如果我运行任何在Ubuntu上构建的旧版Rails应用程序，即使捆绑安装成功完成，它仍会引发错误。我收到的错误消息：
Gem::LoadError: Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).
错误消息不断变化，但是所有与mysql2 gem有关。我从较旧的项目中删除了vendor / cache，Gemfile.lock，但是仍然没有成功。
这个问题确实敲响了警钟，但我没有去挖掘互联网和我的记忆，而是尝试了以下操作：安装最新mysql2的 0.3 系列（在撰写本文时为 0.3.20），并将其捆绑到应用程序中。
问题似乎是最新的mysql2gem 版本 0.4 与 Rails 3 不兼容。
您的 gem 版本无法更改，并且您希望拥有与生产版本相同的版本。为此，您只需Gemfile.lock从生产服务器复制文件，将其放在本地文件夹中Gemfile，然后执行bundle install命令。
请注意，如果您Gemfile指定：
gem 'mysql2', '> 0.3'
0.n然后 Bundler 将安装与where匹配的最新版本n >= 3。在撰写本文时，这会导致 Bundler 获得0.4与您的 Rails 版本不兼容的版本（Bundler 无法从您的 中推断出这一点Gemfile）。您的解决方法是修改您的副本Gemfile（并将其提交到您的项目可能是一个好主意）：
gem 'mysql2', '> 0.3.13' # put here the actual version used in production
这样，Bundler 将安装一个与0.3.n, 和n >= 13.
