ubuntu 16.04 i386 安装 ruby + bundler + rails ; 搭建简单的网站bitbar
参考
http://gorails.com/setup/ubuntu/16.04
一 ruby 2.5.0 +rails 5.0.7.2
先ruby
1.安装 node.js + yarn
遇到问题
sudo systemctl --force --force reboot
解决
sudo systemctl --force --force reboot
sudo apt install curl
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update
sudo apt-get install git-core zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev nodejs yarn
注意apt 换源：
https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
备份原来的源：sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
更换源:sudo vim /etc/apt/sources.list
sudo apt-get update
2.安装ruby 2.4
git clonehttps://github.com/rbenv/rbenv.git ~/.rbenv
echo‘export PATH="$HOME/.rbenv/bin:$PATH"‘ >> ~/.bashrc
echo‘eval "$(rbenv init -)"‘ >> ~/.bashrc
exec$SHELL
git clonehttps://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo‘export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"‘ >>~/.bashrc
exec$SHELL
rbenvinstall 2.5.0
rbenvglobal 2.5.0
ruby -v
3.安装捆绑器
gem install bundler
rbenv rehash
安装 rails
1、gem install rails -v 5.0.7.2
2、如果您使用的是rbenv，则需要运行以下命令以使Rails可执行文件可用：
rbenv rehash
3、rails -v
# Rails 5.0.7.2
4、创建您的第一个Rails应用程序：
#### If you want to use SQLite (notrecommended)
rails new myapp
You can now visit http://localhost:3000 to view your new website!
二 搭建bitbar
- 压缩文件夹为 bitbar.zip
- Ubuntu unzip bitbar.zip
- Cd bitbar .zip
- Bundle install
报错 can‘t find gem bundler (>=0.a) with executable bundler (Gem::GemNotFoundException)
原因是本地bundler版本和项目不一致
参考
https://bundler.io/blog/2019/05/14/solutions-for-cant-find-gem-bundler-with-executable-bundle.html
删除项目的gemfile.lock的bundler版本即可
三 启动服务器
在 /bitbar
Rails server
http://localhost:3000上访问bitbar
终端Ctrl+c关闭服务器
