How to remove Ruby on ubuntu?

Question

How can I remove Ruby 1.9.2dev (2010-07-02) [i486-linux] on ubuntu? Need to reinstall - please help

Answer 1

This command should do the trick (assuming you installed it using the dpkg-based package manager):

aptitude purge ruby 

Answer 2

sudo apt-get purge ruby

It usually works well for me.

Answer 3

First find out where the ruby ​​is? then

 rm -rf /usr/local/lib/ruby rm -rf /usr/lib/ruby rm -f /usr/local/bin/ruby rm -f /usr/bin/ruby rm -f /usr/local/bin/irb rm -f /usr/bin/irb rm -f /usr/local/bin/gem rm -f /usr/bin/gem 

Answer 4

I tried a lot to include sudo apt-get purge ruby , sudo apt-get remove ruby and sudo aptitude purpe ruby , with or without '*' at the end. But none of them worked, maybe I installed several versions of ruby.

Finally, when I tried sudo apt-get purge ruby1.9 (with version), it works.

Answer 5

Here is what sudo apt-get purge ruby* has been removed related to GRUB for me:

 grub-pc grub-gfxpayload-lists grub2-common grub-pc-bin grub-common 

Answer 6

On Lubuntu, I just tried apt-get purge ruby ​​*, and also removing ruby, it looks like this command tried to remove various things related to GRUB, which bothers me a little the next time I want to restart my computer. I still can’t say whether any damage was really done.

Answer 7

decision:

sudo apt-get autoremove ruby

Answer 8

Why are you uninstalling the old version of ruby?

rvm install 2.4.2 // version of ruby ​​u need insatll rvm use 2.4.2 --default // install the ruby ​​version that you want to use by default

Using rvm, you can install several versions of ruby ​​on the system

Please follow these steps: install ruby ​​using rvm

 sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 curl -sSL https://get.rvm.io | bash -s stable source ~/.rvm/scripts/rvm rvm install 2.4.2 rvm use 2.4.2 --default ruby -v 

Installation step will change for another version of Ubuntu

Answer 9

卸载 do the installation 的 软件, do the removal 无效

• make install 时 会 生成 文件 .installed.list
• 选择 清理 .installed.list 中 说明 的 文件 (如果 有 多个 版本 时 需要 特别 小心)

• 案例: ruby2.4 切换 为 ruby2.3, 思路 直接 删除 所有 ruby ​​软件, 然后 重新 make install 2.3

   rm -rf / usr / local / include / ruby- *
   rm -rf / usr / local / lib / ruby
   rm / usr / local / bin / erb / usr / local / bin / gem / usr / local / bin / irb / usr / local / bin / rdoc / usr / local / bin / ri / usr / local / bin / ruby
   rm /usr/local/share/man/man1/erb.1 /usr/local/share/man/man1/irb.1 /usr/local/share/man/man1/ri.1 / usr / local / share / man / man1 / ruby.1
   rm /usr/local/lib/libruby-static.a
   rm -rf / usr / local / lib / pkgconfig / ruby- *
   which ruby
   pkg-config --list-all | grep ruby
  

Uninstall make install software if you make uninstallation invalid.

• make install will create the file '.installed.list'
• Choose to clear the files described in .installed.list (be careful if you have multiple versions)
• Case: ruby2.4 switch to ruby2.3, thinking of directly removing all ruby ​​software, and then reinstalling 2.3 installation, see: Ruby Installation Guide #
• make install -> .installed.list
• see .installed.list file, delete all installation files.

Answer 10

If you used rbenv to install it, you can use

 rbenv versions 

to find out which versions you have installed.

Then use the delete command:

 rbenv uninstall [-f|--force] <version> 

eg:

 rbenv uninstall 2.4.0 # Uninstall Ruby 2.4.0 

If you installed Rails, it will also be uninstalled.

Answer 11

You can use sudo apt remove ruby

Answer 12

 sudo apt-get remove ruby version 

Or use delete
