用Idle運行Python腳本的時候發現如下錯誤：
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] 系統找不到指定的文件。
后來在stackoverflow上找到如下解決辦法：
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 在子進程中使用echo，需要設置 shell =True，因為 echo 不是單獨的命令，而是window CMD 內置的命令
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).
並且，需要注意，只有在絕對需要的情況下才使用shell=True
找到 subprocess.py腳本，將對應行加上shell=true 參數
