在Ubuntu 18.04上为python安装mysqlclient时出错

Question

我在Ubuntu上安装了Python 2.7.15rci和Python 3.6.7。当我在virtualenv上执行“点列表”时，它返回我：

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 install mysqlclient）并返回错误。

  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

因此，我尝试了不同的方法，例如：

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

还有更多...但是它们都不适合我，问题仍然存在。有什么建议么？

谢谢！

Answer 1

我指定了 python 的特定版本，它是 3.7 这对我有帮助

我已经安装了这些：

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

然后通过以下方式安装 mysqlclient：

pip install mysqlclient

Answer 2

gcc是build-essential软件包的一部分，您应该在安装其他软件包之前安装它：

sudo apt-get install build-essential

Answer 3

我发现，几乎每个 Python 版本的解决方案都略有不同。对于那些使用不同版本的人，比如 Python 2.x、3.5 或 3.7，我发现了这个：

第一部分

对于Python 2.x使用：

  $ sudo apt-get install python-dev

对于Python 2.7使用：

  $ sudo apt-get install libffi-dev

对于Python 3.x使用：

  $ sudo apt-get install python3-dev

对于Python 3.4使用：

  $ sudo apt-get install python3.4-dev

对于Python 3.7使用：

  $ sudo apt-get install python3.7-dev

对于Python 3.8使用：

  $ sudo apt-get install python3.8-dev

对于Python 3.9使用：

  $ sudo apt-get install python3.9-dev

第二部分

如果这仍然没有帮助，其他人已经指出安装

  $ sudo apt-get install build-essential

最后

  $ sudo apt-get install libssl-dev

但是最后两个并没有帮助我自己 - 但希望这可以帮助你！
