python2.7-ImportError: No module named _tkinter, please install the python-tk package

这个错误我遇到不止一次了，经常忘！！！这里记一下！！！

完整报错示意：

解法

python2.7用agg做后端的，所以在import matplotlib.pylab前加上matplotlib.use(“agg”)即可。看这里的报错，只要去
/usr/local/lib/python2.7/dist-packages/azimuth/util.py 这里修改前几行即可。

...
import matplotlib # 添加
matplotlib.use("agg") # 添加
import matplotlib.pylab as plt
...
