无法在Ubuntu 12.04下安装MySQL-python

Question

我正在尝试在virtualenv环境下的ubuntu 12.04中安装mysql-python模块，但意外地遇到以下错误：

building '_mysql' extension

creating build/temp.linux-x86_64-2.7

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall
-Wstrict-prototypes -fPIC -Dversion_info=(1,2,5,'final',1) -D__version__=1.2.5 -I/usr/include/mysql -I/usr/include/python2.7 -c _mysql.c -o build/temp.linux-x86_64-2.7/_mysql.o -fPIC -g -fabi-version=2 -fno-omit-frame-pointer -fno-strict-aliasing -DMY_PTHREAD_FASTMUTEX=1

/usr/bin/ld: cannot find -lmysqlclient_r

collect2: ld returned 1 exit status

error: command 'gcc' failed with exit status 1

我跑了：

sudo apt-get install mysql-server mysql-client python-mysqldb libmysqlclient-dev python-dev

但这没有帮助。

Answer 1

问题在于libmysqlclient.so没有https://github.com/javer/gentoo-overlay/issues/4#issuecomment-30748799中描述的符号链接

Answer 2

对于我在Centos上来说，问题是MySQL-python没有提供libmysqlclient_r.so，但是它有其他编号的版本。 通过卸载它并安装Percona-SQL-devel，python能够找到该库并正确构建wheel。
