在我的macbookpro macOS Mojave 10.14.2（18C54）上，我正在使用PyCharm调试我的python代码（Python3.6），在调试模式下出现以下错误消息：

我试图测试哪个代码行触发了此问题，并感到发现“以pd形式导入大熊猫”导致了此问题。 即使使用下面的代码，当我在“ a = 1 + 2”行中切换断点时，调试模式也会异常终止：
import pandas as pd
print("hello world")
a = 1 + 2
print(a)
答案 0 :(得分：3)
此问题是由pandas正在使用的另一个库matplotlib引起的。
解决方法相同，setting the TkAgg backend explictly。将此添加到您的代码中：
import matplotlib
matplotlib.use("TkAgg")
或者，如果您不想编辑代码，则可以使用matplotlib正在读取的以下环境变量：
MPLBACKEND=TkAgg
