安装 IDLEX

IDLEX 是 IDLE 的扩展增强版，项目地址http://idlex.sourceforge.net/about.html

下载后运行idlex.py 会弹出Dos 报错：

NameError: name 'channels' is not defined

错误全部信息如下：

Traceback (most recent call last):
  File "C:\downloads\python\idlex-1.12\idlexlib\extensionManager.py", line 131,
in load_extension
    mod = importlib.import_module('.' + fullname, package=__package__)
  File "C:\Python27\lib\importlib\__init__.py", line 37, in import_module
    __import__(name)
  File "C:\downloads\python\idlex-1.12\idlexlib\extensions\IPyIDLE.py", line 253
, in <module>
    class IdleXSubSocketChannel(SimpleChannel, channels.IOPubChannel):
NameError: name 'channels' is not defined
could not load IPyIDLE

* 出错原因是没安装IPython *

安装 setuptools

参考https://pypi.python.org/pypi/setuptools

在PowerShell中输入

> (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python -

C盘用户目录会出现安装包

> (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content | python - --user

可以看到系统自动将setuptool-18.0.1安装到了 E:\python 所在目录中

这是因为在安装python时，已经在环境变量中加入了 E:\python

安装 IPython

直接在PowerShell中运行

pip install ipython

再回过头来运行idlex.py ,弹出DOS 窗口出现新的错误

ImportError: IPython.kernel.zmq requires pyzmq >= 2.1.11

可以通过

在PowerShell中运行 pip install pyzmq 或者 easy_install pyzmq
