Question

我正在尝试使用Popen(shlex.split(cmd)...和Popen(cmd.split(' ')...执行下面的命令，但是在下面遇到错误，我该如何运行该命令或如何调试该错误？

def function_create_cmds(cmd):
    print cmd
    #proc = Popen(shlex.split(cmd), shell=True, stdout=PIPE, stderr=PIPE)
    proc = Popen(cmd.split(' '), stdout=PIPE, stderr=PIPE)
    (output, error) = proc.communicate()
    return output,error

cmd = "/usr/local/bin/xbs submitproject -notesfile /Users/usernamea/autosubmissionlogs/07162018_133945/milestone/project-375/project-375.plist  -version project-1.0.7 /Users/usernamea/wifiroots/project Release"
(output,error) = function_create_cmds(cmd)
print output
print error

错误：

Popen(cmd.split(' '),

INFO: submitproject was unable to locate a submission directory named 



Popen(shlex.split(cmd)
xbs requires a command

不要使用shell=True，它不需要调用外壳程序来运行您的子进程，因此调用两个进程毫无益处。

proc = Popen(shlex.split(cmd), stdout=PIPE, stderr=PIPE)

应该工作。如果没有，请提供您在这种情况下遇到的错误。

您总是可以自己分割命令：

subprocess.Popen([
    "/usr/local/bin/xbs",
    'submitproject',
    '-notesfile',
    '/Users/usernamea/autosubmissionlogs/07162018_133945/milestone/project-375/project-375.plist',
    '-version',
    'project-1.0.7',
    '/Users/usernamea/wifiroots/project',
    'Release',
])

如何在命令中使用空格运行可执行文件？
