我尝试使用pip install matplotlib安装matplotlib，它重新调整了以下错误。作为参考，我使用的是Windows 7。

为了尝试解决此错误，我们尝试使用以下下载进行安装：https://pypi.python.org/pypi/matplotlib/1.3.0
安装程序返回以下详细信息，然后屏幕消失。

我们假设它已正确安装，因为我们没有看到错误，所以我们尝试了以下示例代码：
import matplotlib.pyplot as plt
#import numpy as np
plt.plot([1,2,3,4],[4,7,9,12])
plt.show()
遗憾的是，它返回了以下追溯：
Traceback (most recent call last):
File "C:\matplotlib_test.py", line 1, in <module>
import matplotlib.pyplot as plt
ImportError: No module named matplotlib.pyplot
有谁知道让这个工作正常吗？
答案 0 :(得分：5)
matplotlib需要运行dateutil，pyparsing和numpy包。如果您没有，pip install python-dateutil和pip install pyparsing也会安装numpy。安装完所有这些依赖项之后，matplotlib应该可以工作。
如果您查看安装程序的消息，您可以看到依赖项列表：
REQUIRED DEPENDENCIES AND EXTENSIONS
numpy: yes [version 1.7.1]
dateutil: yes [dateutil was not found. It is required for date
axis support. pip/easy_install may attempt to
install it after matplotlib.]
tornado: yes [tornado was not found. It is required for the
WebAgg backend. pip/easy_install may attempt to
install it after matplotlib.]
pyparsing: yes [pyparsing was not found. It is required for
mathtext support. pip/easy_install may attempt to
install it after matplotlib.]
pycxx: yes [Couldn't import. Using local copy.]
libagg: yes [pkg-config information for 'libagg' could not
be found. Using local copy.]
freetype: yes [Unknown version]
png: yes [pkg-config information for 'libpng' could not
be found. Using unknown version.]

我遇到了同样的问题所以我完全卸载了python，然后重新安装它作为可在此处下载的PythonXY包的一部分：https://code.google.com/p/pythonxy/
希望这对matplotlib有帮助并祝你好运：）
