帮助让iPython从OSX终端运行

从stackoverflow.com站起来问这里的问题。

我正在浏览matplotlib文档并准备使用iPython交互式Python shell ipython -pylab。但是我得到了这个：

MBP:~ Me$ ipython -pylab
-bash: ipython: command not found

我没有安装iPython吗？我easy_install按照建议使用了。

有任何想法吗？

更新

我以为我只是说/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin在进行Spotlight搜索后我发现了iPython“可执行文件” 。

对于做什么仍然有点困惑。

看起来你的Python 2.6安装是通过MacPorts，基于/opt/local前缀。如果您没有使用MacPorts安装它并且有自己的使用理由/opt/local，请忽略此答案。如果你这样做，你可以安装ipython port。

port install py26-ipython

确保将$PATH环境变量设置为include /opt/local/bin。这应该由MacPorts安装程序完成。我~/.profile看起来像：

# MacPorts Installer addition on 2009-03-05_at_21:11:52: adding an appropriate PATH variable for use with MacPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
# Finished adapting your PATH environment variable for use with MacPorts.


# MacPorts Installer addition on 2009-03-05_at_21:11:52: adding an appropriate MANPATH variable for use with MacPorts.
export MANPATH=/opt/local/share/man:$MANPATH
# Finished adapting your MANPATH environment variable for use with MacPorts.

我会小心地将easy_install与MacPorts python结合使用，特别是对于MacPorts已经提供的模块。例如，MacPorts ipython将可执行文件放在/opt/local/bin/ipython2.6一起/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/ipython

编辑
要卸载easy_installed版本的ipython，据我所知，您需要手动删除相关文件。我根据我的ipython安装进行了一次飞跃。首先删除可执行文件：

/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/ipcluster
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/ipcontroller
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/ipengine
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/iptest
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/ipython
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/ipython-wx
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/ipythonx
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/irunner
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/pycolor

然后，删除site-packages中的文件夹和egg-info：

/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/IPython/
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/ipython-0.10-py2.6.egg-info

然后，删除doc文件夹：

/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/doc/ipython/

然后，删除man文件：

/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/man/man1/ipcluster.1.gz
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/man/man1/ipcontroller.1.gz
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/man/man1/ipengine.1.gz
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/man/man1/ipython-wx.1.gz
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/man/man1/ipython.1.gz
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/man/man1/ipythonx.1.gz
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/man/man1/irunner.1.gz
/opt/local/Library/Frameworks/Python.framework/Versions/2.6/share/man/man1/pycolor.1.gz

最后，打开文件/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/easy-install.pth，查看是否有引用ipython egg的行。删除它。

这听起来像你的PATH问题。检查终端中的〜/ .profile或〜/ .bashrc，并确保在Apple默认之前/ usr / local / bin位于$ PATH中。

PATH="/usr/local/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}"
