Windows7安装Pandas踩过的坑

Windows7安装Pandas踩过的坑

安装Pandas要素：一台网速好的windows7系统的电脑（网速慢也会报错），安装Python3.7.3，最好使用指令安装install -i https://pypi.tuna.tsinghua.edu.cn/simple pandas（如果是离线安装pandas版本和numpy版本不一致也会安装失败）。
报错提示：
1.You are using pip version 19.0.3, however version 20.0.2 is available.
You should consider upgrading via the ‘python -m pip install --upgrade pip’ command.

解决方法：重新运行一次 python -m pip install --upgrade pip

2.raise ReadTimeoutError(self._pool, None, “Read timed out.”)
pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host=‘files.pythonhosted.org’, port=443): Read timed out.

(1)pip --default-timeout=100 install gevent

(2) 如果（1）失败了，尝试一下换成国内的源：pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple pandas
可以参考这个文章：https://www.cnblogs.com/Xingtxx/p/11747165.html
