安装anaconda和python3.7

安装matplotlib报错(参考https://github.com/conda/conda/issues/6007)

解决办法：

Pycharm中配置cando环境

Page01.py文件：
# coding:utf-8
from matplotlib import pyplot as plt

x = range(2, 26, 2)
y = [15, 13, 14.5, 17,20,25,26,26,24,22,18,15]
plt.plot(x,y)
plt.show()

运行简单的画图效果程序报错：

raise ImportError(msg)
ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you\'re working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.

Original error was: DLL load failed: 找不到指定的模块。

画图效果

解决办法将D:\\ProgramData\\Anaconda3\\Library\\bin加入环境变量:
