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),在调试模式下出现错误消息,如下所示：

libc++abi.dylib: terminating with uncaught exception of type NSException
Process finished with exit code 134 (interrupted by signal 6: SIGABRT)
我试图测试哪个代码行触发了此问题,并感觉到是发现“以pd形式导入大熊猫”引起的.
即使使用下面的代码,当我在“ a = 1 2”行切换断点时,调试模式也会异常结束：
import pandas as pd
print("hello world")
a = 1 + 2
print(a)
解决方法:
此问题是由熊猫正在使用的另一个库matplotlib引起的.
和解决方案相同,为setting the TkAgg backend explictly.将其添加到您的代码中：
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
