ruby mysql wrong number of arguments - mysql

I have installed mysql v2.8.1 with ruby v 1.9.3p125.
When I try and connect to a mysql database with:
m = Mysql.new('localhost','root','','dbname')
I get the following error message:
in `initialize': wrong number of arguments(4 for 0) (ArgumentError)
I have tested that mysql is installed by checking gem list and also by issuing the command require 'mysql' from the irb prompt which shows "true".
I have also uninstalled and installed mysql a number of times and tried to install using the instructions shown here: http://thinlight.org/2010/05/12/how-to-install-ruby-mysql-on-mac-os-x-10-6-snow-leopard/
Does anyone have any other suggestions to try?

Try using v0.3.11 of the mysql2 gem instead

I found the solution. I added 'export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"' to my .bash_profile and it worked. – pdoak Jun 12 at 16:49

Error executing task write() argument must be str, not bytes | MySQL Workbench

After a clean install of Windows 10 when I started to use MySQL workbench I have this error when I try to dump a database.
I could not find anything about it anywhere, the only thing I find are problems with phyton, but nothing related with Workbench.
Output after dumping a database:
08:29:00 Dumping foo(all tables)
Error executing task write() argument must be str, not bytes
08:29:01 Export of b'C:\\Users\\erick\\Documents\\dumps\\Dump20210121 (2).sql' has finished
And the output file is in blank, some ideas?
You can disable (uncheck) the option create schema. It is annoying but it works.
If you have the latest MySQL Workbench (8.0.23), just uninstall and install MySQL Workbench 8.0.20. That worked for me.
Another workaround to this issue is to edit wb_admin_export.py.
In dump_to_folder (line 1679) replace
self.out_pipe = open(path,"w")
with
self.out_pipe = open(path,"wb")
In dump_to_file (line 1957) replace
self.out_pipe = open(self.path,"w")
with
self.out_pipe = open(self.path,"wb")
If you a using version 8.0.23, update to 8.0.25 or above.... it will fix this issue

OS X ejabberd configure error: SQLite3 library >= 3.6.19 was not found

I tried to install ejabberd in my local Mac OS X machine, but while configuring sqlite using following command as mentioned in steps. I'm stuck at the following issue.
./configure --prefix=$HOME/my-ejabberd --enable-sqlite
Error received
checking for SQLite3 library >= 3.6.19... yes
cat: /include/sqlite3.h: No such file or directory
./configure: line 4172: test: !=: unary operator expected
configure: WARNING: Cannot find SQLITE_VERSION macro in sqlite3.h header to retrieve SQLite version!
configure: error: SQLite3 library >= 3.6.19 was not found
Steps I followed from - https://docs.ejabberd.im/developer/install-osx/
If you just want to install vanilla Ejabberd then you can simply do brew install ejabberd.
According to the issue, you can also try:
./configure --prefix=$HOME/my-ejabberd --enable-sqlite --with-sqlite3=/usr/local/opt/sqlite
P.S. I have filed the issue on Github Ejabberd.

PDO Exception : Could not find driver. [duplicate]

Does the MySQL-server and PHP5-MySQLi version have to match in order for a connection to be possible? I'm currently receiving the error below: I am running BSD.
"Fatal error: Uncaught exception 'PDOException' with message 'could not find driver'..."
Here is the the connection info:
$info = "mysql:dbname=myDB;host=localhost";
$user = "dbUser";
$pw = "somePW";
return(new PDO($info, $user, $pw));
Here is my MySQL information:
mysql-server-5.5.24
php5-mysqli-5.4.3
I had this same issue on my CentOS install. I had tried to install imagick and hosed my install. When I removed all of my php files and reinstalled something wasn't working right.
I ran:
yum install php-pdo
yum install php-pdo_mysql
After doing those two lines I ran
service httpd restart
and everything came back up and running.
PDO uses database specific drivers to connect to database systems. It looks like you are missing the pdo_mysql driver that is required to connect to a MySQL database. There is some details on installing the driver on the pdo_mysql manual page, or there may be a BSD package that you can use (I am afraid I'm not familiar enough with BSD to offer specific advice).
Thanks to zerkms and John C for pointing me in the right direction. Below are the commands I used to install the driver:
#cd /usr/ports/databases/php5-pdo_mysql
#make install clean
#apachectl restart

Connect to mysql from node.js app, error: "dyld: lazy symbol binding failed: Symbol not found: _mysql_init"

I use OSX 10.6.8 and MySQL from XAMPP.
When I run this node.js app (app.js):
var mysql = require('mysql-libmysqlclient');
var conn = mysql.createConnectionSync();
conn.connectSync('127.0.0.1', 'root', '', 'database_name');
I see this output:
Airs0urce:nodejs airs0urce$ node app.js

Already tried couple solutions after googling.
Added mysql libs from XAMPP directory to include path this way:
export DYLD_LIBRARY_PATH=/Applications/XAMPP/xamppfiles/lib/mysql:$DYLD_LIBRARY_PATH

This is because of a config issue on Mac OS X Lion (10.7): lib/libmysqlclient.18.dylib (mysql 5.5 and above).
Step 1:
Make sure you set the path in ~/.profile
export ARCHFLAGS=-arch x86_64
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
Step 2:
I am using rvm so, I used the following command:
rvmsudo ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config --with-opt-lib=/usr/local/mysql/lib
which has solved the issues with rails application on Mac lion and mysql x86_64.
I futzed around with this for a ton of time including setting the DVLD library path and copying the library into /usr/lib.
sudo cp /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib
Heck, anything to get it working. Finally I tried clearing the default for 64 vs 32 bit and it worked!
defaults delete com.apple.versioner.perl
Not sure if my perl is 64 or 32 bit, but my db is 64 bit and just using the default default seems to work better ;-)

Help with MySQL gem on OSX

I'm trying to get the mysql gem working on OSX 10.5.6, and feeling stymied.
% gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

I'm using the default install of ruby 1.8.6.
I'm using a 64-bit version of MySQL 5.0.77. mysqld is running and I can use the mysql shell, so I suspect my issue is with mysql.gem, though I'm by no means certain.
Can anyone offer any advice?
Ok. So the solution turned out to be I needed to be runing the 32-bit version of MySQL 5.0.77 in order for mysql.gem to work.
