我不能使用rvm在Ubuntu中安装morden

Question

我使用RVM来安装ruby2.2.0，rvm install 2.2.0 --disable-binary，但是我得到了错误：

  Error running 'requirements_debian_update_system ruby-2.2.0',

  showing last 15 lines of /home/gaoyikang/.rvm/log/1471531667_ruby-2.2.0/update_system.log
   ++ case "${TERM:-dumb}" in
   ++ case "$1" in
   ++ [[ -t 2 ]]
   ++ return 1
   ++ printf %b 'There has been error while updating '\''apt-get'\'',        please give it some time and try again later.
   404 errors should be fixed for rvm to proceed. Check your sources configured in:
/etc/apt/sources.list
/etc/apt/sources.list.d/*.list\n'

Requirements installation failed with status: 100.

我不知道该怎么修？有人遇到过这个问题吗？

Answer 1

试试这个：

sudo apt-get update

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

然后安装Ruby的最新版本或所需版本。
