I'm trying to install packetgen, a library for crafting and manipulating network packets. I followed all the instructions, and installed all the necessary libraries. However, when I ran sudo gem install packetgen
to install it on my Linux machine it raised an error:
ERROR: Error installing packetgen:

I ran the command as sudo, but got the same error. Does anyone know what I'm doing wrong here? The link to installation instructions is here.
Don't use sudo gem install but rather it is highly recommended that you use a ruby version manager, probably RVM, for more reasons why, see 'sudo gem install' or 'gem install' and gem locations
Based on your error it looks like you're trying to use your system ruby which will likely have permission and/or library dependency issues. These are easily solved by using a version manager which has many advantages including the ability to use different ruby versions on the same system and not having to use sudo or root level installs of gems.
You can install RVM from here
Instructions on gem link you posted do say gem depends on sudo apt install libpcap-dev which is a system lib your gem needs to build. I assume you did that step already right?

I've written a Ruby gem that I'd like to install locally. I'm using Rubygems 3.0.6 and RVM on OS X Mojave. This is a closed source gem and I'd rather not go to the trouble of publishing it to the company gemservers. I'm able to install other (published) gems just fine using both bundle install and gem install.
The gem is all built (using gem build) and the code works, but when I run:
gem install influx_trello_utility-0.1.0.gem
I get an error:
ERROR: While executing gem ... (Gem::Package::PathError)
installing into parent path /bin/[ of /Users/danascheider/.rvm/gems/ruby-2.6.3#influx_trello_utility/gems/influx_trello_utility-0.1.0 is not allowed
Any help with this would be much appreciated. I'm not sure what additional information would be useful, but I'm happy to answer any questions you may have. Thanks!

what i do is:
1. install ruby, path variable was set, version: ruby 2.5.1p57 (2018-03-29 revision 63029) [x64-mingw32].
2. install rubygems, version: 2.7.7.
3. install MSYS2.
4. install jekyll, gem install jekyll, then the above error occurs and i'm not sure the reason.
i have tried to install devkit and it not works, i think my ruby version is 2.5+, so don't need devkit and i have uninstalled it.
Anyone could help me?
Although they made the Ruby+DevKit an "optional" download for the RubyInstaller on Windows, if you plan to install gems, it is practically a necessity. A large percentage of the most popular gems are C extension that will need built on your machine when being installed.
The DevKit is a handy toolchain that supplies everything you need for this to be done, automatically without you needed to do anything more than type gem install XXXXX. Without it, you either cannot use C extension gems, or must have already installed MSYS and MingW, have them configured properly, which is all not a user-friendly experience, even for those who familiar with the process.
So even if DevKit is optional, it is still required to make the most of Ruby on Windows.
Solution re-install ruby with rubyinstaller-devkit-2.5.5-1-x64
and issue
gem install bundler
gem install jekyll
I got the same error message. It turned out that the culprit was the ffi gem. I got it to work using this solution.
I had the same issue. I was able to resolve it (in Windows 11 x64) via:
winget install -e --id RubyInstallerTeam.RubyWithDevKit
(I.e., reinstall Ruby with the DevKit)
Even I have installed ruby-dev and ruby-make but still giving same error ? how to fix the error ?

You don't have the source code for Ruby so when it attempts to compile the gem it fails. It's looking for /usr/lib/ruby/include/ruby.h but that file isn't present on your system.
Generally, it's not a good idea to use the system version of Ruby. (for this reason, and others) You should use a Ruby manager to install Ruby into your user profile, as this will make compiling gems a lot easier.
For example, you can use RVM to install Ruby:
\curl -sSL https://get.rvm.io | bash -s stable
This will install the latest version of rvm, which you can then use to install Ruby 2.4:
rvm install 2.4
You can install nearly any version of Ruby by specifying its version, for example Ruby 2.5:
rvm install 2.5
Afterwards, running ruby will automatically run the version installed by RVM. And since it's installed in your profile, you don't need to use sudo for any operations. (and you should never use sudo when using rvm or Rubies installed by rvm)
In your case, you would then be able to run gem install mechanize successfully because it would be using the Ruby installation in your home directory that includes a copy of the source code and header files.
If for some reason you can't use RVM or don't want to use RVM, then you need to have the Ruby header files installed. The way to install these headers varies by operating system so there's no one answer I can give you. If your OS is a Debian-based version of Linux, for example, you can install the headers with:
sudo apt-get install ruby2.4-dev
More information is available in another answer on stackoverflow.
So I attempted to install Jekyll on Windows through Cygwin and I encountered an error when I tried to install Jekyll through Cygwin. Here is the output.

I conducted some research online and I wasn't able to find a solution. I tried running Cygwin as an administrator and I still got that error message.
What can I do to fix this issue?
I had the same issue when installing Jekyll and Ruby in the Windows 10 Bash Linux Subsystem. It turned out, that the development package from Ruby was missing. I had to install it first:
sudo apt-get install ruby2.4-dev
In my case. Try to install the dev package in Cygwin package manager, in your case its version 2.3.
Andy
For the record, I encountered the same problem Michael did, and installing the ruby-devel package (using the Cygwin Setup installer) solved my problem. A missing *-devel Cygwin package is a common cause of errors about missing header files.
I have installed Ruby on Rails on my Ubuntu 10.04 Server by official tutorial: https://help.ubuntu.com/10.04/serverguide/C/ruby-on-rails.html
But I have some troubles with it. Please, help me!

If you are not set on using the packages in the Ubuntu repos(and I see no reason why you'd be), I'd suggest following this guide:
http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you
Consider going through and making sure your sqlite3 libraries are installed. It looks as though you may be missing the required dependencies to build your gem. In this case you might try running this before installing your gem:
sudo apt-get install libsqlite3-dev
Also, try
rails --version
instead.
