Building native extension. This could take a while...

我安装的Ruby版本是1.9.3p194

尝试安装RedCloth时，为什么会出现此错误？

Answer 1

要解决此问题，我必须更新到最新版本的Ruby，或者至少1.9.3

我从root运行以下几组命令，它适用于我：

apt-get -y remove ruby
apt-get -y install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion locales-all python libxml2
curl -L https://get.rvm.io | bash -s stable --rails
source /usr/local/rvm/scripts/rvm

这将完全安装最新版本的Ruby，然后你可以运行：

gem install RedCloth -v '4.2.9'

现在将安装RedCloth。 RVM将管理您的Ruby安装。 Ruby现在也可以工作。
