Python退出MacOS Big Sur

Question

最近我将我的操作系统升级到MacOS Big Sur，Pycharm无法与我的代码一起运行。错误消息表示python在当前操作系统中意外退出。matplotlib等函数会触发此问题

Answer 1

在Big Sur升级后，我遇到了完全相同的问题。它在Python3.6中保持不变 我找到了一个临时解决方法，将plt.show（）行替换为plt.savefig（“文件名”）。当然，这是一种使用舒适性的丧失

现在，通过从Python3.6转换到3.9，完全解决了这个问题

Answer 2

这似乎是一个版本问题。我将它转换为Python3.6，问题就解决了。也许python 3.7和更高版本不能支持这些LIB

Answer 3

我在python2.7.16中遇到了类似的问题，我尝试将matplotlib版本降级到1.5.3，然后解决了问题

pip install  user matplotlib==1.5.3

也许也可以试试Python3的较低版本
