I am using Windows 7 and creating connection to MySQL2. I need to install gem. I am following these steps. Could someone please review them:
Add the following to the Gemfile: gem 'mysql2', '~> 0.3.15'
Run the following in cmd: gem install mysql2 -v '0.3.15'
Go to the application using cmd and run this code: bundle install
When I perform step (3), I get the following error:
An error occurred while installing mysql2 (0.3.15), and bundler cannot
continue make sure that `gem install mysql2 -v "0.3.15" ' succeeds
before bundling..
My application resides on the D drive and I am using Windows 7.
I have found a solution that works on Ubuntu.
My mistake was that had not installed the my-sql library before trying to connect.
Please follow these steps to do this. Run the following commands:
sudo apt-get install mysql-client libmysqlclient-dev
sudo gem install mysql2
Add the following to the gemfile
gem 'mysql2', '~> 0.3.15'
And then run:
bundle install

To start I'm pretty new at rails which I'm sure this question will show. I was about to follow the steps on gorails.com to setup a local server. I also use codeanywhere for when I have internet access. When I try to install (rails new myapp) rails I keep getting the following error from my terminal command
extconf failed, exit code 1
Gem files will remain installed in

Any Help on the matter would be greatly appreciated. Thanks in advance.
Please edit the file in your ruby rails project named Gemfile and change following
gem 'sqlite3'
to
gem 'sqlite3', '~> 1.3.11'
Now run following command to install Gem
bundle install
now run your rails project
rails s
I think you are missing sqlite3.
Run the command
sudo apt-get install -y sqlite3 libsqlite3-dev
Then modify gemfile to
gem 'sqlite3', '~> 1.3.11'
Then run
bundle install
In rails some packages needs to be installed in your local ,after which they can be included in your gemfile. The same applies for mysql and psql.
I am still fairly new to Rails. I am trying to push to Heroku and I am getting errors.
The first error is when I run a Bundle Install I get this error message:
"An error occurred while installing pg (1.1.3), and Bundler cannot continue.
Make sure that gem install pg -v '1.1.3' succeeds before bundling."
I have tried to run this command
gem install pg -v '1.1.3'
But it fails and gives me this error message:
"ERROR: Error installing pg:
ERROR: Failed to build gem native extension."
Does anyone have a solution to this?
I had the exact same problem, and solved it by running sudo apt install postgresql-contrib libpq-dev. Then bundle worked just fine.
if you're using OSX, you could try running
brew install postgresql
and then installing the gem
TL;DR; If you installed the Postgres using the PostgresAPP instead of BREW then the problem might be that you don't have the postgres bin folder in the $APTH
The solution is to find the Posgres app installation folder an in it the /bin folder.
In my case if I run which postgres doesn't work which means I don't have it in my $PATH, so what I did is I navigated to: cd /Applications/Posgres.app then to Contents and then to Versions until I found the latest folder:
/Applications/Postgres.app/Contents/Versions/latest/bin
Now, with this I can install the PG GEM by providing the path to the bin folder of my Postgres app installation
Finally, in the terminal in the root of my Rails project I ran where I provide the postgres config file path to the GEM installer:
gem install pg -v '1.2.3' -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/latest/bin/pg_config
I encountered the same problem. I am using Ubuntu. I installed Postgres using this Ubuntu guide. After installing Postgres, I ran this code sudo apt install postgresql-contrib libpq-dev then bundle install.
The accepted answer is not correct. If you installed postgresql-contrib and libpq-dev as mentioned in Cesar Faria answer, and you still getting the same error, most probable you missed the list of packages which are considered essential for building Debian packages. All that packages included in build-essential package. So, all you need to do to get rid of the error is the command below.
sudo apt install libpq-dev build-essential
try instaling with pg-config like this:
gem install pg -v 1.1.3 -- --with-pg-config=/usr/pgsql-9.X/bin/pg_config.
In pg-config path mention the posgtres version installed in you're system.
Postgresql needs to be in local in order to install gem pg. Try this
brew install postgresql
and the re-install bundle
bundle install
or
If you are using yum. Try this
sudo yum install postgresql-devel
The following is only for your local environment:
Note: Update the command below to match your version postgresql/13.2/...
> brew install postgres
> sudo gem install pg -v '1.1.4' --source 'https://rubygems.org/' -- --with-pg-config=/usr/local/Cellar/postgresql/13.2/bin/pg_config
Also, make sure to start your server > pg_ctl -D /usr/local/var/postgres start
I git cloned a repo. I cannot run it on localhost with rails server because terminal says
Could not find activesupport-4.2.5 in any of the sources Run bundle
install to install missing gems.
When I run bundle install, I get
An error occurred while installing pg (0.18.4), and Bundler cannot
continue. Make sure that gem install pg -v '0.18.4' succeeds before
bundling.
I have rails 4.2.3, and the repo's Gemfile has gem 'rails', '4.2.5'. I don't know if this matter
Gem pg is Postgres driver, it only can be installed, if corresponding headers and libraries are present and can be accessed.
Most probably just installing postgres will fix it. If you're on a Mac with homebrew - brew install postgresql
Install postgresql.
Remove Gemfile.lock
Add gem 'pg' in your gemfile
execute bundle install
1: Remove Gemfile.lock if Gemgile.lock present in your project
2: add gem 'pg' # in Gemfile
3: Run bundle install
Hope this help you !!!
Run
sudo env ARCHFLAGS="-arch x86_64" gem install pg -v '1.18.4'
Now try running bundle install again.
I used a combination of #Chakreshwar Sharma and #Vinay's answers to get this working for the metasploit-framework.
Remove Gemfile.lock
Add gem 'pg' in your gemfile
Run apt-cache search postgresql-server-dev
apt-get update && apt-get install postgresql-server-dev-9.5 # Check your version
bundle install --no-deployment
To be honest, I think you could just run:
apt-cache search postgresql-server-dev
apt-cache search postgresql-server-dev-9.5
bundle install
...and you can avoid messing with the Gemfile, but I didn't get to verify it since mine started working after I made the adjustments.
I am unable to install mysql2 gem .
I have recently installed ruby 2 and rails 4 version .
I am not able to install mysql2 gem, getting the below error when i run the command gem install mysql2:
Some index files failed to download. They have been ignored, or old ones used instead.
Make sure that the following packages are installed first
sudo apt-get install mysql-client mysql-server libmysqlclient-dev
You may need to run
sudo apt-get update
before installing them
You should provide more information. But here some thoughts:
Why are you using gem install mysql2 instead of adding the gem to your Gemfile and run bundle?
I had some issues with Rails 4 and mysql2 v0.4.x and downgraded to v0.3.20
I got this error
Could not find mysql2-0.3.13 in any of the sources
Run `bundle install` to install missing gems.
I tried to gem install mysql2 but without luck, it didn't fix it. I'm using wampp server and copied the libmysql.ddl to the bin folder of ruby. I also tried adding the path to the gem install just like this.
gem install mysql2 --platform=ruby -- ‘-with-mysql-lib=”C:\wamp\bin\mysql\mysql5.5.24\lib” -with-mysql-include=”C:\wamp\bin\mysql\mysql5.5.24\include”‘
Any ideas on how to fix this? THanks!
First, make sure you have mysql installed on your machine.
If you have an Ubuntu distribution, try:
sudo apt-get install libmysql-ruby libmysqlclient-dev
then try to install the gem again.
I installed mysql2 from sources like this
# i experienced some troubles with mysql2 0.3.13 installing
gem fetch mysql2 -v 0.3.12
gem install mysql2-0.3.12.gem -- ' --with-mysql-include="c:\Program Files (x86)\MariaDB 5.5\include\mysql" --with-mysql-lib="c:\Program Files (x86)\MariaDB 5.5\lib" '
But after each Gemfile updating and bundle install, bundler is installing precompiled version of mysql2 gem and it's very annoying. After manual removing precompiled gem rails app started successfully
P.S. You also need installed Ruby DevKit.
