Python ipcluster3.exe无法创建进程

我正在尝试在64位Windows 7上的Anaconda python 3.3安装上运行ipcluster3.exe

但是，当我运行它时，我得到一个错误：

C:\Anaconda\envs\py33\Scripts>ipcluster3.exe
failed to create process.

C:\Anaconda\envs\py33\Scripts>ipcluster3.exe start -n 4
failed to create process.

---

这个错误并没有给我足够的时间开始调试。

看起来我的Anacondas副本附带了IPython的Beta版

我用康达更新了它

conda update -n py33 ipython
