问题描述

过去2周,我一直在尝试在Mac上设置我的代码.以前我使用的是Ubuntu,设置代码从未如此困难.我几乎遵循了所有教程,但是没有运气.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.

I have been trying from last 2 weeks to setup my code on Mac. Previously I was using Ubuntu, it was never this difficult to setup code. I have followed almost all tutorials but no luck. Please can anyone guide me on setting up RoR on mac. After following all the tutorials I end up at mysql error only.

在Ubuntu中用于设置Rails的步骤:

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:mysql Ver 14.14 Distrib 5.7.9, forosx10.11 (x86_64) using EditLine wrapper安装了MySQL.遵循mysql安装后在屏幕上给出的命令.

  • installed MySQL using brew:mysql Ver 14.14 Distrib 5.7.9, forosx10.11 (x86_64) using EditLine wrapper. Followed the commands given onscreen after mysql installation.

通过以下步骤安装了rvm:

installed rvm with the following steps:

\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

已安装的滑轨,gem install rails,当前版本为'4.2.5'.

installed rails, gem install rails, current version is '4.2.5'.

(mysql2 gem版本(0.4.2)用rails 4.2.5唤醒)

(mysql2 gem version (0.4.2) woking with rails 4.2.5)

(mysql2 gem版本(0.3.20)用rails 3.2.14唤醒)

(mysql2 gem version (0.3.20) woking with rails 3.2.14)

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上构建的旧版本的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:

So, now I am able to create and run new rails app, but if I run any older rails app built on Ubuntu, it keeps throwing error even though bundle install completes successfully. The error message which I get:

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,但所有消息均与mysql2 gem有关.我已经从较旧的项目中删除了供应商/缓存 Gemfile.lock ,但仍然没有成功.

The error messages keeps changing but all are related to mysql2 gem. I have deleted vendor/cache, Gemfile.lock from my older project but still no success.

推荐答案

此问题的确响起了警钟,但我没有尝试挖掘Internet和我的记忆,而是尝试了以下操作:安装最新版本的mysql2 0.3系列(撰写本文时为0.3.20),并将其捆绑到应用程序中.

This problem does ring a bell, but instead of digging out the Internet and my memory, I have just tried the following: Install the latest mysql2 of the 0.3 series (0.3.20 at time of writing), and bundle it up for the application.

问题似乎是最新的mysql2 gem版本0.4与Rails 3不兼容.

The problem seems that the latest mysql2 gem version 0.4 is not compatible with Rails 3.

您的宝石版本无法更改,并且您希望具有与生产版本相同的版本.为此,您只需从生产服务器复制您的Gemfile.lock文件,将其放在Gemfile旁边的本地文件夹中,然后执行bundle install命令.

Your gem versions cannot be changed, and you want to have the same versions as production. To do so, you could just copy over your Gemfile.lock file from the production server, put it in your local folder aside the Gemfile, and execute the bundle install command.

请注意,如果您的Gemfile指定:

Note that if your Gemfile specifies:

gem 'mysql2', '> 0.3'

然后,Bundler将安装与0.n匹配的最新版本,其中n >= 3.在撰写本文时,这导致Bundler获得0.4版本,该版本与您的Rails版本不兼容(Bundler无法从您的Gemfile推断出该版本).一种解决方法是修改Gemfile的副本(并将其提交到您的项目中可能是个好主意):

Then Bundler will install the latest version that matches 0.n where n >= 3. At time of writing, that leads Bundler to get a 0.4 version, which is not compatible with your Rails version (Bundler cannot infer that from your Gemfile). A workaround for you is to modify your copy of the Gemfile (and committing it to your project may be a good idea):

gem 'mysql2', '> 0.3.13'  # put here the actual version used in production

这样做,Bundler将安装与0.3.n匹配且与n >= 13匹配的版本.

Doing so, Bundler will install a version matchings 0.3.n, with n >= 13.
