从崇高的文本打开 ipython

Question

我在 sublime text 2 中添加了以下插件，用于打开 ipython qt 控制台：

import sublime, sublime_plugin
from subprocess import call
# import os

class ipythonQtCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        call(["start","ipython", "qtconsole", "--pylab", "--ConsoleWidget.font_size=9", "--ConsoleWidget.font_family='Consolas'"],shell=True)

最初它工作得很好，即插件打开了一个 ipython shell。然后我添加了一个菜单项和一个键绑定。在某些时候一定出了问题，因为现在我在运行插件时遇到了这个错误：

Traceback (most recent call last):

ImportError: Module use of python26.dll conflicts with this version of Python.

我通过在 st2 shell 本身中逐行运行脚本来测试脚本，它是导致错误的最后一行 call([...])。我觉得这有点奇怪，因为从其他地方调用它时该命令可以正常工作，例如ipython 本身。

Answer 1

好像和st2原生的python有冲突。无论如何，当使用os.chdir() 更改工作目录时，我设法让os.system(...) 工作。
