问题描述

我正在努力在系统范围内或安装了MariaDB 10的Ubuntu 14.04上的venv中安装mysql-python pip.还尝试使用MariaDB 5.5并得到相同的错误.我没有安装香草mysql服务器的问题.

I'm struggling to install the mysql-python pip either systemwide or in a venv on Ubuntu 14.04 with MariaDB 10 installed. Also tried with MariaDB 5.5 and getting the same error. I don't have this issue with vanilla mysql-server installed.

我通过apt-get安装了以下内容:

I have the following installed via apt-get:

  • 基本要件
  • python-dev
  • libmariadbclient-dev(这是libmysqlclient-dev的MariaDB替代品)
  • python-mysqldb

最初,我认为将其安装到venv中是一个问题,但后来我注意到mysql-python也不会在系统范围内安装.以下是我曾经在Venv中安装的cmd.

Originally I thought this was an issue installing this into a venv but I've subsequently noticed mysql-python won't install systemwide either. Below are the cmds I used to install in a venv.

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

我所做的与您相同,但仍然无法重现该问题:

I did the same as you did, and still couldn't reproduce the issue:

但是,您有两条我没有的信息,即:

But, there were two messages that you have that I didn't, namely:

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

如果您执行了ld -lcrypto --verboseld -lssl --verbose,则不会产生此结果:

Which if you did ld -lcrypto --verbose or ld -lssl --verbose wouldn't produce this results:

➜  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,只需确保已安装提供两个库的libssl-dev软件包即可.

So, to fix this just make sure you have installed the libssl-dev package which provides both libraries.
