01-安装rails开发坏境

ubuntu/debian 环境安装 rails

1. 更新 系统环境及安装开发环境

sudo apt update && sudo apt upgrade

sudo apt-get install git-core curl zlib1g-dev build-essential \
libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libmariadbd-dev \
                     libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common  zlib1g-dev

2. 安装 rbenv

git clone git@github.com:rbenv/rbenv.git ~/.rbenv
git clone https://github.com/rbenv/rbenv.git ~/.rbenv

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc

echo 'eval "$(rbenv init -)"' >> ~/.bashrc

git clone git@github.com:rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc

git clone git@github.com:AndorChen/rbenv-china-mirror.git ~/.rbenv/plugins/rbenv-china-mirror
git clone https://github.com/AndorChen/rbenv-china-mirror.git ~/.rbenv/plugins/rbenv-ch
git clone https://github.com/rkh/rbenv-update.git ~/.rbenv/plugins/rbenv-update
exec $SHELL

3. 安装ruby

rbenv install 2.4.1

rbenv global 2.4.1

4. 设置国内源

gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/
gem sources -l
https://gems.ruby-china.com
# 确保只有 gems.ruby-china.com

5. 安装rails

echo "gem: --no-ri --no-rdoc" > ~/.gemrc  # 可以让gem下载速度快一些 不用下载不必要的说明文档


gem install rails

6. 设置bundler的源地址映像

bundle config mirror.https://rubygems.org https://gems.ruby-china.com

7. 安装 nodejs， rails 运行的时候需要有js的运行环境

可以添加 node 官方源 用 apt安装最新版nodejs
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt install nodejs
#或者 如果同时还在用node.js开发 也可以使用nvm

ps. 如果rbenv一直提示需要安装 openssl 请添加环境变量

export RUBY_CONFIGURE_OPTS="--with-openssl-dir=/usr/local/opt/openssl@1.1"

mac osx安装rails环境

1. 安装xcode CLT

xcode-select --install

2 第2步开始与上面的相同

ps.如使用 zsh,将 .bashrc 换成 .zshrc
