Question

我花了差不多30分钟的时间尝试所有不同的东西。最后我现在筋疲力尽了。有人可以帮我解决这个引用问题

def remote_shell_func_execute():
    with settings(host_string='user@XXX.yyy.com',warn_only=True):
            process = run("subprocess.Popen(\["/root/test/shell_script_for_test.sh func2"\],shell=True,stdin=subprocess.PIPE,stdout=subprocess.PIPE,stderr=subprocess.PIPE)")
            process.wait()
            for line in process.stdout.readlines():
                    print(line)

当运行晶圆厂时，我得到了

fab remote_shell_func_execute
Traceback (most recent call last):

                                                                           ^
SyntaxError: invalid syntax

Answer 1

只使用一个带引号的字符串。

run('subprocess.Popen(\["/root/test/shell_script_for_test.sh func2"\],shell=True,stdin=subprocess.PIPE,stdout=subprocess.PIPE,stderr=subprocess.PIPE)')

或逃避内部"。

run("subprocess.Popen(\[\"/root/test/shell_script_for_test.sh func2\"\],shell=True,stdin=subprocess.PIPE,stdout=subprocess.PIPE,stderr=subprocess.PIPE)")

当您转义引号时，转义反斜杠必须直接在引号字符之前：

"[\"/..."

或者，对字符串使用单引号，这样就不需要转义：

'["/...'
