SublimeREPL: OSError：[WinError 6]句柄无效

Question

我在SublimeREPL中使用R，但无法将代码发送到R会话。下面是我正在使用的键绑定：

{ "keys": ["ctrl+enter"], "command": "repl_transfer_current", "args": {"scope": "selection"}},
{ "keys": ["ctrl+enter"], "command": "repl_transfer_current", "args": {"scope": "selection", "action":"view_write"}},

{ "keys": ["ctrl+alt+enter"], "command": "repl_transfer_current", "args": {"scope": "lines"}},
{ "keys": ["ctrl+alt+enter"], "command": "repl_transfer_current", "args": {"scope": "lines", "action":"view_write"}},

下面是Sublime的日志：

command: repl_transfer_current {"action": "view_write", "scope": "selection"}
Traceback (most recent call last):

    if not (rv.repl and rv.repl.is_alive()):
  File "C:\Users\~\AppData\Roaming\Sublime Text 3\Packages\SublimeREPL\repls\subprocess_repl.py", line 209, in is_alive
    return self.popen.poll() is None
  File "./python3.3/subprocess.py", line 930, in poll
  File "./python3.3/subprocess.py", line 1145, in _internal_poll
OSError: [WinError 6] The handle is invalid

基于this线程，我将subprocess_repl.py中的is_alive设置为返回True，而不是调用self.popen.poll()，从而解决了这个问题。

def is_alive(self):
    # return self.popen.poll() is None
    return True
