Python下载numpy和pandas踩过的大坑

最直接的安装方法是在python的scripts中执行 pip install pandas后，能出现Successfull是最好的，这也代表你已完成pandas的安装。下面的内容对你也没有用了。但是一般执行完后，dos窗口会出现各种报错。（Ps:我也是在网上找了各种各样的解决办法，看的人头大。下面是我的解决方法）

出现报错：

E:Python34Scripts>pip install pandas

...............(报错信息太多，这边就不详细写了)

我的解决方法：

1、https://www.lfd.uci.edu/~gohlke/pythonlibs/ 在该网址查找你自己对应的版本的numpy和pandas模块下载，需要下载在python的安装路径下的Scripts中。

2、在E:Python34Scripts路径上直接输入cmd命令，系统弹出dos窗口，然后执行pip install numpy-1.15.4+mkl-cp34-cp34m-win_amd64.whl（numpy-1.15.4+mkl-cp34-cp34m-win_amd64.whl代表的是你本地下载的numpy版本），执行结果出现Successfully installed numpy-1.15.4+mkl 代表numpy已安装成功。

E:Python34Scripts>pip install numpy-1.15.4+mkl-cp34-cp34m-win_amd64.whl

Processing e:python34scripts umpy-1.15.4+mkl-cp34-cp34m-win_amd64.whl

3、在E:Python34Scripts路径上直接输入cmd命令，系统弹出dos窗口，然后执行pip install pandas-0.20.3-cp34-cp34m-win_amd64.whl（pandas-0.20.3-cp34-cp34m-win_amd64.whl代表的是你本地下载的pandas版本），执行结果出现Successfully installed installed pandas-0.20.3 python-dateutil-2.7.5 pytz-2018.9 six-1.12.0 代表pandas已安装成功。
