ruby-on-rails - 安装 Ruby 时出错

Question

我用过this程序。我正在使用 Linux Mint。

安装时出现以下错误。

E: Unable to locate package libreadline6-dev
E: Unable to locate package libyaml-dev
E: Unable to locate package libgdbm-dev
E: Package 'ncurses-dev' has no installation candidate
E: Package 'bison' has no installation candidate
E: Package 'subversion' has no installation candidate
E: Package 'libffi-dev' has no installation candidate

Answer 1

我认为您没有安装rvm 要求。
安装要求，如 libreadline6-dev ， libyaml-dev ， libgdbm-dev 等..
我认为这将解决问题。

使用命令安装所有这些

sudo apt-get 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 pkg-config
