Python subprocess.run是'；在使用pyinstaller和--noconsole--onefile时无法工作

我正在使用Pyinstaller 3.6、Python3.8.3，在编译此代码时（使用标志--onefile）：

一切正常。下面是output.txt文件：

 Volume in drive C has no label.

 Volume Serial Number is E612-C89D

 Directory of C:\Users\trolo\OneDrive\Desktop\progs\tests\dist

[WinError 6] The handle is invalid

出了什么问题，如何在不显示控制台窗口的情况下使其工作？

Python3:您只需传递stdin=subprocess.DEVNULL即可

subprocess.Popen( args=[self.exec_path], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, stdin=subprocess.DEVNULL)

Python2.x：您需要将filehandler设置为null，然后将其传递给popen

devnull = open(os.devnull, 'wb')
subprocess.Popen( args=[self.exec_path], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, stdin=devnull)

这帮了大忙。谢谢

devnull = open(os.devnull, 'wb')
subprocess.Popen( args=[self.exec_path], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, stdin=devnull)
