ipython(0.13.1)安裝及與virtualenv(1.9.1)一起使用

1. create ipython profile setting file:

$ ipython profile create

• 建立~/.config/ipython/profile_default/ipython_config.py

$ ipython profile create <name>

• 建立~/.config/ipython/ <name> /ipython_config.py

2. 啟動ipython

• 可指定 profile, 或不指定則使用default profile

$ ipython --profile=<name>

• 初次啟用時發生錯誤, ImportError: No module named IPython.frontend.terminal.ipapp, 需在/usr/bin/ipython檔案加入

import sys
if "/usr/lib/python2.7/dist-packages" not in sys.path:
    sys.path.append("/usr/lib/python2.7/dist-packages")

3. 讓ipython 與 virtualenv一併使用:

• 需要在ipython_config.py中加入

import site
from os import environ
from os.path import join
import sys

if 'VIRTUAL_ENV' in environ:
    virtual_env = join(environ.get('VIRTUAL_ENV'),
                       'lib',
                       'python%d.%d' % sys.version_info[:2],
                       'site-packages')

    # Remember original sys.path.
    prev_sys_path = list(sys.path)
    site.addsitedir(virtual_env)

    # Personal hack
    # Remove /usr/lib/python2.7/dist-packages and associates from the path
    # Counter the effects of this code, in /usr/bin/ipython
    # import sys
        # if "/usr/lib/python2.7/dist-packages" not in sys.path:
    #     sys.path.append("/usr/lib/python2.7/dist-packages")
    for item in sys.path:
        if '/usr/lib/python2.7/dist-packages' in item:
            sys.path.remove(item)


    # Reorder sys.path so new directories at the front.
    new_sys_path = []
    for item in list(sys.path):
        if item not in prev_sys_path:
            new_sys_path.append(item)
            sys.path.remove(item)
    sys.path[1:1] = new_sys_path

    print 'VIRTUAL_ENV ->', virtual_env
    del virtual_env
del sys, site, environ, join
