Python - Windows - Popen（shlex.split（command），shell = False会导致OSError：[Errno 2]没有这样的文件或目录

Question

我正在运行此代码在OSX中正常工作但在Windows上导致错误：

command = "C:\\progra~2\\itms\\iTMSTransporter -m verify -f /Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp -u username -p password -o /Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp/LOGFILE.txt -s provider -v eXtreme" 
self.process1 = Popen(shlex.split(command), shell=False, stdin=PIPE) 

我在Windows recieving的错误是：

WindowsError: [Error 2] The system cannot find the file specified 

为什么给我在Windows这个错误

你shlex.split()破坏因为删除\字符的路径让我们来看看？：

import shlex 
command = "C:\\progra~2\\itms\\iTMSTransporter -m verify -f Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp -u username -p password -o /Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp/LOGFILE.txt -s provider -v eXtreme" 
print shlex.split(command) 

['C:progra~2itmsiTMSTransporter', '-m', 'verify', '-f', '/Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp', '-u', 'username', '-p', 'password', '-o', '/Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp/LOGFILE.txt', '-s', 'provider', '-v', 'eXtreme'] 

正如你所看到的，路径可执行文件是不正确（C:progra~2itmsiTMSTransporter），所以POPEN无法找到它。

更改路径分隔符/，这是在Linux/Windows环境的安全：

command = "C:/progra~2/itms/iTMSTransporter -m verify -f Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp -u username -p password -o /Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp/LOGFILE.txt -s provider -v eXtreme" 
print shlex.split(command) 

['C:/progra~2/itms/iTMSTransporter', '-m', 'verify', '-f', 'Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp', '-u', 'username', '-p', 'password', '-o', '/Volumes/Stuff/Temp/TMP_S_0_V_TV2.itmsp/LOGFILE.txt', '-s', 'provider', '-v', 'eXtreme'] 

Popen()正确处理这条道路。
