使用mariaDB库安装mysql-python时"找不到-lssl;找不到-lcrypto"

我正在努力在系统范围内或在安装了MariaDB 10的Ubuntu 14.04上的venv中安装mysql-python pip.还尝试使用MariaDB 5.5并获得相同的错误.我没有安装vanilla mysql-server这个问题.

我通过apt-get安装了以下内容:

建立必要的

蟒蛇-dev的

libmariadbclient-dev(这就是用于libmysqlclient-dev的MariaDB替代品)

蟒蛇,MySQLdb的

最初我认为这是一个安装到venv中的问题,但我后来发现mysql-python也不会在全系统安装.下面是我用来安装在venv中的cmds.

virtualenv venv
. venv/bin/activate
pip install mysql-python==1.2.5

我做了同样的事情,仍然无法重现问题:

但是,你有两条我没有的消息,即:

/usr/bin/ld: cannot find -lssl
/usr/bin/ld: cannot find -lcrypto

如果你做了ld -lcrypto --verbose或ld -lssl --verbose不会产生这个结果:

?  src  ld -lcrypto --verbose | grep succeeded
attempt to open //usr/lib/x86_64-linux-gnu/libcrypto.so succeeded
ld: warning: cannot find entry symbol _start; not setting start address
?  src  ld -lssl --verbose | grep succeeded
attempt to open //usr/lib/x86_64-linux-gnu/libssl.so succeeded
ld: warning: cannot find entry symbol _start; not setting start address

因此,要解决此问题,请确保已安装libssl-dev提供两个库的软件包.
