Python下載numpy和pandas踩過的大坑
Python下載numpy和pandas踩過的大坑
最直接的安裝方法是在python的scripts中執行 pip install pandas後，能出現Successfull是最好的，這也代表你已完成pandas的安裝。下面的內容對你也沒有用了。但是一般執行完後，dos窗口會出現各種報錯。（Ps:我也是在網上找了各種各樣的解決辦法，看的人頭大。下面是我的解決方法）
出現報錯：

我的解決方法：
1、https://www.lfd.uci.edu/~gohlke/pythonlibs/ 在該網址查找你自己對應的版本的numpy和pandas模塊下載，需要下載在python的安裝路徑下的Scripts中。
2、在E:\Python34\Scripts
E:\Python34\Scripts>pip install numpy-1.15.4+mkl-cp34-cp34m-win_amd64.whl
Processing e:\python34\scripts\numpy-1.15.4+mkl-cp34-cp34m-win_amd64.whl
Installing collected packages: numpy
Successfully installed numpy-1.15.4+mkl
3、在E:\Python34\Scripts路徑上直接輸入cmd命令，系統彈出dos窗口，然後執行pip install pandas-0.20.3-cp34-cp34m-win_amd64.whl（pandas-0.20.3-cp34-cp34m-win_amd64.whl代表的是你本地下載的pandas版本），執行結果出現Successfully installed installed pandas-0.20.3 python-dateutil-2.7.5 pytz-2018.9 six-1.12.0 代表pandas已安裝成功。
