python debug please

报错说No module named 'matplotlip 我应该怎么办

import matplotlip.pyplot as plt
import numpy as np

# Data for plotting
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2 * np.pi * t)

fig, ax = plt.subplots()
ax.plot(t, s)

ax.set(xlabel='time (s)', ylabel='voltage (mV)',
       title='About as simple as it gets, folks')
ax.grid()

fig.savefig("test.png")
plt.show()

导错包了，是matplotlib

import matplotlib.pyplot as plt
import numpy as np
 
# Data for plotting
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2 * np.pi * t)
 
fig, ax = plt.subplots()
ax.plot(t, s)
 
ax.set(xlabel='time (s)', ylabel='voltage (mV)',
       title='About as simple as it gets, folks')
ax.grid()
 
fig.savefig("test.png")
plt.show()

（这个模块的名字叫做matplotlib，不是matplotlip）应该是import matplotlib.pyplot as plt。
其次如果还导入不了的话，应该是没有下载这个第三方模块，命令行（cmd）输入: pip install matplotlib
