问题
I recently updated my system to Ubuntu 18.04 LTS, and since then, the Ruby version seems to have updated to 2.5. The issue is that, when attempting to deploy a project that uses Capistrano, it will now complain that Ruby 2.3 was not found.
The version it tries to install when running rvm install 2.3 is 2.3.4, and the first error that is shown is "Error running '__rvm_make -j4'". I tried removing RVM and installing again, but nothing solves this. The log is an enormous file which tells me nothing.
Then, I tried using rbenv, which also causes an error:
Installing ruby-2.3.4...

The log file also has a stupid giant log file.
The next attempt was to install from source, which after running make within the folder, the error:

What is it there to be done to install it? Or it isn't possible anymore to install these old versions?
回答1:
I had a same issue, though it seemed problem was in gcc, in my case problem was in libssl-dev, this is what helped me:
sudo apt purge libssl-dev && sudo apt install libssl1.0-dev
I use rbenv. If you use rvm, you might hit problem after running previous command:
/usr/share/rvm/scripts/base: No such file or directory
I recommend trying rbenv. After installing libssl1.0-dev, everything was flawless.
回答2:
Got it working also with RVM:
1. sudo apt purge libssl-dev && sudo apt install libssl1.0-dev
2. rvm install 2.3.5 --autolibs=disable
You must install RVM dependencies manually, otherwise, with autolibs enabled, RVM will try to update system dependencies and also libssl-dev (that you downgraded in the first step). If you don't want to manually install dependencies you can try to install Ruby with autolibs enabled, the installation will fail, at this point you have dependencies installalled, so you can downgrade libssl repeating all from step 1.
回答3:
cd ~/src
wget https://www.openssl.org/source/openssl-1.0.2s.tar.gz
tar xvzf openssl-1.0.2s.tar.gz
cd openssl-1.0.2s
mkdir ~/.rubies/openssl-1.0.2s
./config --prefix=$HOME/.rubies/openssl-1.0.2s --shared
make
make install
RUBY_CONFIGURE_OPTS=--with-openssl-dir=$HOME/.rubies/openssl-1.0.2s rbenv install 2.3.1
worked for me
回答4:
Solved that issue by updating rvm
rvm get head
回答5:
In order to install libssl-dev on Ubuntu 20.04. Use this command to to do that. It worked for me:
sudo apt install libssl-dev/focal
回答6:
I have a similar problem. Apparently the ruby version < 2.3 is incompatible with openssl 1.1 which come with the lastest versions of Ubuntu. Here i found a solution for ArchLinux, I tried this solution and ruby compiled fine, but i had a lot memory bugs in rails then my unique solution for now is use ruby > 2.4 until i found other solution.
回答7:
Try this with rvm
rvm install ruby-2.3.4
Or perhaps try https://gorails.com/setup/ubuntu/18.04
You probably are missing required libraries so try running these first:
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
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 nodejs yarn
