使用 ruby​​-install 應用程式在 Ubuntu 12.04 上安裝 ruby​​ 2.1

我已經閱讀了一些關於如何安裝 ruby​​ 2.1 的教程。 * 我的系統目前有 ruby​​ 1.9.3，我想要最新的。我正在按照以下教程了解如何從此處安裝它：http://ryanbigg.com/2014/10/ubuntu-ruby-ruby-install-chruby-and-you //

到目前為止，這些是我執行的命令：

sudo apt-get install build-essential

wget -O ruby-install-0.5.0.tar.gz \
  https://github.com/postmodern/ruby-install/archive/v0.5.0.tar.gz
tar -xzvf ruby-install-0.5.0.tar.gz
cd ruby-install-0.5.0/
sudo make install

ruby-install ruby 2.1.3
DEPENDENCY ERRORS

一旦我開始 ruby​​-install ruby​​ 2.1.3，我就會遇到這個問題：

>>> Installing ruby 2.1.3 into /opt/rubies/ruby-2.1.3 ...
>>> Installing dependencies for ruby 2.1.3 ...

好吧，它說我缺少所有這些依賴項。我怎麼才能讓他們安裝它，這樣它就可以停止抱怨？為什麼沒有一個命令只說“好吧，您缺少這些依賴項，讓我為您安裝它們（是/否）？

以下是根據官方說明在基於 Debian 的系統中安裝 Ruby 2.1 的命令Ruby Dockerfile。順便說一句，您可以使用 Docker 來避免這種痛苦。

# Update your system packages
apt-get update 

# Install some basic dependencies
# Few of thems aren't needed but won't hurt anyway
apt-get install -y \
    autoconf \
    build-essential \
    imagemagick \
    libbz2-dev \
    libcurl4-openssl-dev \
    libevent-dev \
    libffi-dev \
    libglib2.0-dev \
    libjpeg-dev \
    libmagickcore-dev \
    libmagickwand-dev \
    libmysqlclient-dev \
    libncurses-dev \
    libpq-dev \
    libreadline-dev \
    libsqlite3-dev \
    libssl-dev \
    libxml2-dev \
    libxslt-dev \
    libyaml-dev \
    zlib1g-dev \

apt-get install -y curl procps

RUBY_MAJOR="2.1"
RUBY_VERSION="2.1.5"

apt-get install -y bison ruby

mkdir -p /usr/src/ruby
curl -SL "http://cache.ruby-lang.org/pub/ruby/$RUBY_MAJOR/ruby-$RUBY_VERSION.tar.bz2" | tar -xjC /usr/src/ruby --strip-components=1
cd /usr/src/ruby
autoconf
./configure --disable-install-doc
make -j"$(nproc)"
apt-get purge -y --auto-remove bison ruby
make install
rm -r /usr/src/ruby

GEM_HOME="/usr/local/bundle"
PATH=$PATH:$GEM_HOME/bin
gem install bundler
bundle config --global path "$GEM_HOME"
bundle config --global bin "$GEM_HOME/bin"

正如您可以想像的那樣，某些命令需要在 sudo 模式下輸入。

此時您應該已經安裝了 Ruby 2.1.5。要驗證，請輸入ruby -v.

注意：我尚未對此進行測試，因此請隨時提供回饋。
