用Idle运行Python脚本的时候发现如下错误:
Traceback (most recent call last):
File "C:\Users\DangKai\Desktop\pythonUI-unittest-selenium\venv\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start
stdin=PIPE)
File "D:\Software\Python37\lib\subprocess.py", line 756, in init
restore_signals, start_new_session)
File "D:\Software\Python37\lib\subprocess.py", line 1155, in _execute_child
startupinfo)
FileNotFoundError: [WinError 2] 系统找不到指定的文件。
后来在stackoverflow上找到如下解决办法:
In Windows , to use echo in subprocess, you would need to use shell=True . This is because echo is not a separate executable, but rather a built-in command for the windows command line. Example - 在windows 在子进程中使用echo,需要设置 shell =True,因为 echo 不是单独的命令,而是window CMD 内置的命令
process1 = subprocess.Popen(command1,stdout=subprocess.PIPE,shell=True)
Also, please do note, you should only use shell=True when absolutely necessary (as in this case , to use echo in windows in subprocess).
并且,需要注意,只有在绝对需要的情况下才使用shell=True
找到 subprocess.py脚本,将对应行加上shell=true 参数
FileNotFoundError: [WinError 2] 系统找不到指定的文件。 解决方案
