我正在尝试为 Sublime 编写一个插件,它将读取当前行的文本,将其作为 shell 命令执行,并将命令的输出放入编辑器中。这是我到目前为止所拥有的:

import sublime, sublime_plugin, os, os.path
import subprocess

def GetLineAtCursor(view):
    pos = view.sel()[0].a
    reg = view.line(pos)
    return view.substr(reg)

class ExecuteLineGetOutputCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        line = GetLineAtCursor(self.view).strip().split()
        output = subprocess.check_output(line,shell=True)
        self.view.insert(edit, 0, output)

这是行不通的。具体来说,调用subprocess.check_output(...)不起作用,尽管它在 python 解释器中工作正常。我把它放在一个 try 块中,如下所示:

try:
    output = subprocess.check_output(line,shell=True)
except Exception as e:
    self.view.insert(edit, 0, str(e))

无论我尝试什么命令,它都会产生以下输出:

[WinError 6] The handle is invalid

有谁知道问题是什么,以及如何解决?

尝试这个:

def run(self, edit):
    line = GetLineAtCursor(self.view).strip().split()
    cmd = [line, 'attr1', 'attr2']

    # if windows
    p = subprocess.Popen(cmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, startupinfo=startupinfo, shell=False, creationflags=subprocess.SW_HIDE)
    #else unix/macos
    p = subprocess.Popen(cmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)    

    output, stderr = p.communicate()

    if (stderr):
        print(stderr)
    self.view.insert(edit, 0, output)
