Got "undefined method `split'" when installing gem dm-mysql-adapter - ruby

I'm trying to install the gem dm-mysql-adapter with the following
command:
gem install dm-mysql-adapter -- --with-mysql-config=/usr/bin/mysql
--with-mysql-lib=/usr/lib/mysql
and got this result:

Has anyone experience the same problem? What should I do to fix this?
Thanks!

I had this exact same problem. I'm on OS X 10.6 with the latest MySQL 5.1 package from dev.mysql.com.
Anyway, it turns out the fix was really simple, I just needed to add the mysql bin directory to my path:
$ export PATH=$PATH:/usr/local/mysql/bin
Then, from the same command prompt (because the path only gets changed for that session), I installed the gem with the following command:
sudo sudo env ARCHFLAGS="-arch x86_64" gem install dm-mysql-adapter
I appreciate that this question is 3 months old, but this page is the top hit for 'can't install dm-mysql-adapter on osx', and hopefully this will help somebody out.

On Mac Big Sur (11.6.2), first running
brew install mysql
and then runnimg the gem command worked for me.

In my case I had to install mysql-client first. At the end of install brew tells where /bin is - you may need to replace it
brew install mysql-client
export PATH=$PATH:/usr/local/opt/mysql-client/bin
gem install mysql2

I got a similar error when running gem install mysql2 -v 0.5.4 on Manjaro.
I solved it by running sudo pacman -S mysql

Bundler v2.0.2 refuses to install libxml-ruby 3.1.0 on Mac OS Catalina

I have found all of the answers of how to install libxml-ruby with the gem install command:
gem install libxml-ruby -v '3.1.0' -- --with-xml2-config=/usr/local/opt/libxml2/bin/xml2-config --with-xml2-dir=/usr/local/opt/libxml2 --with-xml2-lib=/usr/local/opt/libxml2/lib --with-xml2-include=/usr/local/opt/libxml2/include
Works beautifully! But then running this right afterward:
bundle install
gives the unhelpful error:
Fetching libxml-ruby 3.1.0
Installing libxml-ruby 3.1.0 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

OK, it looks like the libxml2 options are not being included in the call the bundler uses to install. So let's do this:
bundle config build.libxml-ruby --with-xml2-config=/usr/local/opt/libxml2/bin/xml2-config --with-xml2-dir=/usr/local/opt/libxml2 --with-xml2-lib=/usr/local/opt/libxml2/lib --with-xml2-include=/usr/local/opt/libxml2/include
That should work, right? Well no it doesn't. I am dead in the water until I can get Bundler to do what it is supposed to do.
There is no good answer for why Bundler fails here. The gem install line works. Bundler fails.
Inside the mkmf.log file is this:
find_header: checking for libxml/xmlversion.h in /opt/include/libxml2,/opt/local/include/libxml2,/usr/local/include/libxml2,/usr/include/libxml2... -------------------- no
And then several failures that all relate to not being able to find that header file.
It's looking in /opt/, instead of /usr/local/opt. I don't know how to make Bundler look in the correct place if it won't respect the bundle config commands.
Since Bundler wouldn't honor the paths I was passing in, I looked at the paths where it was looking for xmlversion.h.
I went into /usr/local/include. That's where all my Homebrew links are. I created a symlink to the Mac OS-provided libxml directory:
ln -s /usr/local/opt/libxml2/include/libxml2/libxml libxml
/usr/local/opt seems like a strange place for a system directory, but I'm tired of messing with it.
Once I did this, and went back into my app directory, bundle install worked. Well, I mean it broke again but it was on therubyracer this time. So it at least jumped this hurdle.

Ruby sqlite3 gem installation issue on Windows 10

I am very new to ruby and rails. I am trying to install to sqlite3 for trying a tutorial and having issues. I am on Windows 10 and using ruby 2.6.1p33 (2019-01-30 revision 66950) [x64-mingw32].

I have downloaded sqlite3 from their site and here is the folder structure of C:\sqlite3\
sqldiff.exe
sqlite3.exe
sqlite3_analyzer.exe
include\shell.c
include\sqlite3.c
include\sqlite3.h
include\sqlite3ext.h
lib\sqlite3.def
lib\sqlite3.dll
I have also copied sqldiff.exe, sqlite3.exe and sqlite3_analyzer.exe to C:\Ruby26-x64\bin.
In my environment variable, I have added C:\sqlite3\ to PATH and also created a new environment variable sqlite3-dir pointing to C:\sqlite3\
Could someone please provide some help for this installation problem?
adding gem 'sqlite3', git: "https://github.com/larskanis/sqlite3-ruby", branch: "add-gemspec" in the project Gemfile file works. After that run bundle install. Make sure to install git in the machine. This is the github link
For solving this issue for all the projects I downloaded the gem file from https://rubygems.org/ and saved it locally, installed MinGW by cmd
C:\Sites>ridk exec pacman -S mingw-w64-x86_64-dlfcn
and the SQLite 3 gem after
C:\Sites>gem install --local C:\sqlite3-1.4.0.gem
and it worked for all the next projects created on Sites folder if you need to fix a project already created trying running bundle install again after those lines.
I also tried including the SQLite 3 files to the path but it didn't work for me either
This is what has currently worked for me and it's a per project fix; Samiul Alam Anik's answer, but with an addition. After you follow those steps, you might get a requires Bundler 2 and this is solved for me with gem update --system thanks to this GitHub ticket.
Make sure you have current Ruby version installed on your computer, install node ja, install yarn, update npm, update gem Ruby.

Install error rb-appscript extconf.rb failed

Fairly new to this so I've been trying to awhile to figure this out but unable to locate an answer.

When installing the rb-appscript I get the following error.

First, I hope you're enjoying Ruby. :-)
The Config module was renamed and deprecated to RbConfig around Ruby 1.9 (not sure when exactly). Config was removed entirely in Ruby 2, hence the uninitialized constant Config fatal error.
If you'd happened to be using 1.9.x instead of 2.2.2, you would have seen a deprecation warning, which probably would have tipped you off.
(localhost) ~ ruby -e "puts Config::CONFIG['RUBY_PROGRAM_VERSION']"
-e:1: Use RbConfig instead of obsolete and deprecated Config.
1.9.3
(localhost) ~ ruby -e "puts RbConfig::CONFIG['RUBY_PROGRAM_VERSION']"

2.2.3
You could probably use Ruby 1.9 if you want to use rb-appscript, but I've never used that gem, so I can't speak to it specifically.
(You can easily install a version of 1.9 with rbenv and its ruby-build plugin.)
Are you on OSX? Make sure you installed/upgraded the latest XCode from the AppStore. Then run:
gcc -v
If that fails, you may have to accept the xcode license by running:
sudo gcc -v
and following the instructions.
Alternatively, you may install the XCode command line tools with:
xcode-select --install
Then re-run:
gem install gem_name

I am working on Mac OS 10.7.5. Xcode and its command line tools and Rails are up to date.
SQLite 3 is also installed.
Can anyone help me?
EDIT:
I also tried to delete the repository and to clone it again, with the same errors.
EDIT:
Is the installation path of Rails and Sqlite3 correct?

At least one problem is that you are running RVM, but used sudo to install gems on your system.
Read "RVM and RubyGems", especially the part that says:
"DO NOT use sudo..."
RVM creates a sandbox for you, the user, in your own user-space on a machine, that allows you to manage it without needing to be the system administrator. In other words, that means you don't have to use sudo for any RVM or gems management.
If you do use sudo, you temporarily cease being you, the user, and become the administrator, with administrator privileges and the administrator's environment, which does NOT include the RVM sandbox in your /Users/daniel/.rvm/rubies/ruby-1.9.3-p286 path. Knowledge of the sandbox is carried by the PATH in your environment, which the root on your machine doesn't use. Gems installed inside that sudo sub-shell get installed into the location that the administrator account knows about, which is inside the System Ruby installation, which is why your RVM sandboxed Ruby doesn't see them: There is no crossover between the System's Ruby and your RVM-controlled RUby. That's the whole idea of a sandbox: separation of the elements and resources to avoid contamination.
You could have figured this all out by looking at the output of:
which ruby irb gem rake
The path for all of them is pointing to your sandbox:
/Users/daniel/.rvm/rubies
On a Mac OS system, that command should have reported:
/usr/bin/ruby
/usr/bin/irb
/usr/bin/gem
/usr/bin/rake
Reinstall Rails and the SQLite gem using:
gem install rails sqlite3
and see how your bundle behaves.
And, by the way, do NOT use sudo to deliberately try to manage/delete the System installed Ruby. That was installed by Apple for their own purposes, to enable software they installed. It's OK to take advantage of its existence, but it's there for their use. Use a RVM-managed Ruby for your own purposes.

Typically, this just means you need to install the development libraries and everything is cool. However, I have installed the sqlite-devel packages and still no dice. Since this is the Amazon Linux instance, I'd rather not add more repositories than the ones Amazon provides if possible. What can i do to get this thing to compile? Thanks for any insight!
From a brand new instance, here's what I've done:
$ sudo yum install rubygems ruby-devel
$ sudo gem update --system
$ sudo gem install rails
$ rails new app
$ cd app
$ rails server
Could not find gem 'sqlite3 (>= 0)' in any of the gem sources listed in your Gemfile.
$ sudo yum install sqlite-devel
$ sudo gem install sqlite (or sqlite3 -- same result)
See breakage above. And note - I do realize I can comment out the line in the gemfile to get rails to run but I actually need the gem. Thanks in advance!
Ran into this as well. Surprisingly the stock amazon linux doesn't have make or gcc installed.
sudo yum install gcc
sudo yum install make
$ sudo yum install libsqlite3-dev
Note the version 3.
Or if the package is available in your OS install libsqlite3-ruby
