我正在尝试使用rbenv安装Ruby 2.4.0，我收到错误，如下所示

`a@a:~$ rbenv install 2.4.0

Answer 1

可能这些步骤可以帮助您解决问题

mkdir ~/.rbenv/cache
rbenv install 2.4.0

或

mkdir ~/.rbenv/cache
# download manually ruby file
wget https://cache.ruby-lang.org/pub/ruby/2.4/ruby-2.4.0.tar.bz2
# move file
mv ruby-2.4.0.tar.bz2 ~/.rbenv/cache
# do the install
rbenv install 2.4.0
