Question

我想要安装一个我推荐使用pip或easy_install的新软件包，两者都会抛出以下错误，我可以找出原因。

我已经清除了temp文件夹，因为一开始认为这是问题。

我刚刚错过了pip错误，但如果需要可以添加easy_install

Answer 1

安装Python 3.3或更高版本。检查PyMySQL的最低要求：

https://pypi.python.org/pypi/PyMySQL#id1

Answer 2

code of PyMySQL使用Unicode文字。

错误消息的追溯中的目录名的py3.2部分告诉我您正在使用Python 3.2。虽然Python 2具有Unicode文字，但Python 3.0到3.2并没有：语法是removed with Python 3.0：

您无法再将u"..."文字用于Unicode文字。

re-introduced with Python 3.3 PEP 414出于向后兼容性原因，这是Boaz stated。

作为Padraic pointed out和{{3}}，PyMySQL需要Python2.x≥2.6或3.x≥3.3，因此PyMySQL的作者可以随意使用Unicode代码中的文字语法。

运行Python pip和easy_install会抛出错误
