Mac installation Mysqldb-python

In the middle of a lot of problems, now put the information found here, for reference only

http://blog.csdn.net/janronehoo/article/details/25207825

Installation environment: OS X operating system, Python 2.7.3.

MySQLdb is actually included in the Mysql-python package, so you should search for Mysql-python whether you download or search in PIP.

The following is a description of the MySQLdb two common installation methods, download installation or PIP installation Mysql-python.　

Download MySQLdb

In SourceForge you can download Mysql-python-1.2.4b4.tar, unzip it after downloading, and then execute the following command in Terminal Terminal:

new-host-3:~ ifantastic$ cd/users/ifantastic/downloads/mysql-python-1.2.4b4

NEW-HOST-3:MYSQL-PYTHON-1.2.4B4 ifantastic$ python setup.py install

Installing MYSQLDB with PIP

Execute in Terminal:

new-host-Install Mysql-python

Whether you are installing online or downloading an installation, you may encounter the first error message:

Not found

It is recommended to use PIP installation because the version I downloaded from SourceForge is not as new as the PIP. If you want to upgrade the Mysql-python version, you can use the following command:

$ easy_install Mysql-python--upgrade

[Note] If you do not follow the instructions below to resolve the installation errors, the upgrade will also fail for the same cause of error.

Resolve Mysql_config not found error

When you install the Mac version of MySQL by default, the Mysql_config file is generated in the/usr/local/mysql/bin directory.

Therefore, the solution to download the installation is: Locate the Site.cfg file in the Mysql-python installation package, open it, and locate the following:

# the path to mysql_config.< Span style= "line-height:1.5!important; margin:0px; Color: #008000; padding:0px; " ># only use this if Mysql_ Config is isn't on your PATH, or you have some weird# setup that requires it.< Span style= "line-height:1.5!important; margin:0px; Color: #008000; padding:0px; " ># Mysql_config =/usr/ Local/bin/mysql_config

Remove the last sentence first and modify it as follows:

Mysql_config =/usr/local/mysql/bin/mysql_config

Then execute:

$ python setup.py Install

Generally speaking, the installation can be completed at this point, but there are still problems, as described below.

There is no way to modify the Site.cfg file when using PIP installation, so you can resolve errors that cannot be found by modifying OS X's system environment variables.

　　Modify OS x environment variable: Open terminal, use VIM in terminal to open "~/.bash_profile", if no vim is installed, then show hidden file Open with text editor, the operation here is no longer described. In. Bash_profile, add the following:

  "/usr/local/mysql/bin:$ {PATH}  "export pathexport dyld_library_path=/usr/local/mysql/lib/export versioner_python_prefer_64_bit=       

Among them versioner_python_prefer_64_bit and versioner_python_prefer_64_bit according to their own installation of MySQL to choose.

In addition, a PIP installation can not find the Mysql_config solution (I did not verify), enter the following command in the terminal:

$ sudo ln-s/usr/local/mysql/bin/*/usr/bin

Well, here, Mysql-python package should be basically smooth installation.

Resolve Reason:image not found error

After installing the Mysql-python package, let us import mysqldb, there is an error, the last line of error is written reason:image not found.

The workaround is to execute at the terminal:

$ sudo ln-s/usr/local/mysql/lib/libmysqlclient.18.dylib/usr/lib/libmysqlclient.18. dylib$ sudo ln-s/usr/local/ Mysql/lib/usr/local/mysql/lib/mysql

Error:

Clang:error: Unknown argument: '-mno-fused-madd ' [-wunused-command-line-argument-hard-error-in-future]

clang:note:this 'll be a hard error (cannot is downgraded to a warning) in the future

Verified on-line: Http://www.tuicool.com/articles/zI7Vzu, seemingly Mac OS Xcode from 5.1 to compiler rules for unknown parameter incoming as error, We need to downgrade this error to warning using archflags, so the final installation command should look like this:

sudo archflags=-wno-error=unused-command-line-argument-hard-error-in-future python setup.py build

MYSQLDB error in installing Python module under Mac OS X and resolution

Using Python on your Mac, there are more problems than CentOS, and here's a solution to this problem.
The following error is prompted with MySQLdb in your Mac:

Traceback (most recent):  file "./b", line +, in     import mysqldb  File "/library/python/2.7/ site-packages/mysql_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/mysqldb/__init__.py ", line +, in     import _ Mysqlimporterror:dlopen (/library/python/2.7/site-packages/mysql_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/_ Mysql.so, 2): no suitable image found.  Did Find:/library/python/2.7/site-packages/mysql_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/_mysql.so:mach-o, But wrong architecture

The reason is that because Macs are different from other Linux, some dynamic libraries need to be compiled manually, especially if the Mac is a 64-bit operating system, so turn this option on to recompile. To do this, edit under the current User:

Vim ~/.bash_profile

Add the following (remove line numbers):

Path= "/usr/local/mysql/bin:${path}" export PATH from export DYLD_LIBRARY_PATH=/USR/LOCAL/MYSQL/LIB/25 export Versioner_python_prefer_64_bit=yes Export Versioner_python_prefer_32_bit=yes

Then load the modified configuration:

SOURCE ~/.bash_profile

Then enter the Mysqlpython directory and compile the installation:

Python setup.py buildpython setup.py Install

It is important to note that Bash_profile are modified and loaded under different users, otherwise the non-current user cannot take effect.

Http://rabbit52.com/2012/desktopos/mac/mac-dyld_library_path-error

After you install MySQL and python-mysqldb on your MAC, you cannot import the "Dyld_library_path" environment variable in Python, which is usually added

Export dyld_library_path= "/usr/local/mysql/lib: $DYLD _library_path"

Resolved, but doing so will cause an error when the terminal executes the sudo command

DYLD:DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid

Actually, this is a bug in Mountain Lion.

But there is a way to solve, if you have the cause of the problem and I, then execute the following command and delete the top of the environment variable configuration is OK

sudo ln-s/usr/local/mysql/lib/libmysqlclient.18.dylib/usr/lib/libmysqlclient.18.dylib
