在Ubuntu18.04上为python安装mysqlclient时出错

Question

我在Ubuntu上安装了Python2.7.15rci和Python3.6.7。当我在virtualenv上执行“pip list”时，它会返回我：

Django (2.1.5)
pip (9.0.1)
pkg-resources (0.0.0)
pytz (2018.9)
setuptools (39.0.1)
wheel (0.32.3)

我正在尝试安装mysqlclient (pip安装mysqlclient)并返回一个错误。

  unable to execute 'x86_64-linux-gnu-gcc': No such file or directory
  error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

所以，我尝试了不同的方法，比如：

sudo apt-get install python-dev
sudo apt-get install python3-dev
sudo apt-get install libmysqlclient-dev

再来点..。但他们都不适合我，而且问题依然存在。有什么建议吗？

谢谢!

Answer 1

gcc是build-essential包的一部分，您应该先安装它：

sudo apt-get install build-essential

更新:按照@bosnjak的建议，您可能还需要安装openssl工具：

sudo apt-get install libssl-dev

Answer 2

我指定了python的特定版本，它是3.7，这帮助了我

我安装了这些：

sudo apt-get install python3.7-dev libmysqlclient-dev

然后通过以下方式安装mysqlclient：

pip install mysqlclient

Answer 3

我发现，几乎每个Python版本的解决方案都略有不同。对于使用不同版本(如Python2.x、3.5或3.7 )的用户，我发现了this

第一部分

对于Python2.x，请使用：

  $ sudo apt-get install python-dev

对于Python2.7，使用：

  $ sudo apt-get install libffi-dev

对于Python3.x，请使用：

  $ sudo apt-get install python3-dev

对于Python3.4，请使用：

  $ sudo apt-get install python3.4-dev

对于Python3.7，请使用：

  $ sudo apt-get install python3.7-dev

对于Python3.8，请使用：

  $ sudo apt-get install python3.8-dev

对于Python3.9，请使用：

  $ sudo apt-get install python3.9-dev

第二部分

如果这仍然没有帮助的话，others已经指出要安装

  $ sudo apt-get install build-essential

最后

  $ sudo apt-get install libssl-dev

但最后两个人帮不了我自己--但希望这能帮到你！
