Python GUI在cmd运行时冻结，但不是通过Pycharm

所以我已经看了很长一段时间了，但我不能解决这个问题

这里的目标是让它逐行显示从cmd/terminal到tkinter ScrolledText/Text小部件的实时结果，除非在Windows上通过cmd运行

我正在Linux（Kali）和Windows10上运行代码。如果我在Windows10上使用Pycharm运行它，那么它将平稳运行，GUI不会冻结，等待使用Pexpect运行代码。 如果我通过cmd（

python tmp_stack.py

）运行代码，那么它将冻结GUI，直到Pexpect完成我要求它运行的文件。
在Linux终端上，代码运行良好，不会冻结（在针对Linux进行调整后）。
我将多个文件合并到

tmp_stack.py

中，以防止无真正原因地创建更多文件。
我已经测试过该配置在Windows和Linux上运行相同

旁注：我不介意更改为

subprocess.Popen

，如果它不会抱怨主循环并且可以工作，我也不介意使用

线程

尝试在禁用输出缓冲的情况下运行子Python进程

换言之，尝试更换线路

        cmd = ['python', filename]

与

另见

        cmd = ['python', '-u', filename]
