我试图安装Pandas library uisgpip3，但出现以下错误：

这里有什么问题，如何解决

Answer 1

我猜您使用的python版本太高，请参见类似问题12

您可以试试python 3.6。在安装软件包之前，您应该始终升级pip

正如您在pip安装日志中所看到的，它试图从一些C/C++源代码进行编译，这需要构建工具，而这些工具有时是不可用的

因此，我建议您使用anaconda，从wiki：

Anaconda is a distribution of the Python and R programming languages for scientific computing (data science, machine learning applications, large-scale data processing, predictive analytics, etc.), that aims to simplify package management and deployment.
