我是python的新手，正在使用pip下载和安装软件包。我在命令窗口运行以下代码并抛出错误

pip install matplotlib

它会产生这些追溯错误。我无法弄清楚这些错误是什么以及如何解决它们。请帮忙。它可以很好地工作直到收集包装，但在安装时它会引发错误。

Answer 1

尝试python -m pip install matplotlib。

或

以管理员身份打开cmd
然后python -m pip install matplotlib

Answer 2

如果您使用的是Windows，安装许多面向数字的Python软件包的最简单方法是从http://www.lfd.uci.edu/~gohlke/pythonlibs/下载包含预编译二进制文件的一个轮子，并使用pip进行安装：

pip install SomePackage-1.0-py2.py3-none-any.whl

确保为Python安装下载右轮版本（Python2或Python3,32位或64位）。

使用pip安装matplotlib会出错
