Question

调试程序时，只要调试器遇到断点（我已使用print语句确认），它就会向控制台发送以下错误：

Traceback (most recent call last):
  File "/Applications/PyCharm CE.app/Contents/helpers/pydev/pydevd_frame.py", line 408, in trace_dispatch

除非我在代码中放置断点，否则会发生这种情况。在该行总是会出错。关于其原因和/或解决方案的任何想法？

Answer 1

有点明显，但我希望确保你的断点在语法上是正确的。如果您知道只有在放置断点的地方发生错误，那么它必须是您如何写出来的。

Answer 2

正如我上面提到的，我遇到了同样的问题，在咨询Jet Brains社区论坛后，我找到了解决方案。我们的matplotlibtools库安装已损坏。

再次安装或升级它，错误应该消失。
