已安装iPython但未找到 [英] iPython installed but not found
问题描述
我最近删除了Anaconda并用brew重新安装了python。我根据这些说明。
I've recently deleted Anaconda and reinstalled python with brew. I've installed everything according to these instructions.
Python效果很好，到目前为止我测试的所有软件包都可以使用。我已经安装了ipython，但尝试从终端启动它给出：
Python works great, and all packages I've tested so far also work. I've got ipython installed, but trying to launch it from the terminal gives:
-bash：ipython：command not found
-bash: ipython: command not found
我找到了安装位置：
/usr/local/lib/python2.7/site-packages/ipython
/usr/local/lib/python2.7/site-packages/ipython
关于较早的相关问题，我试过添加这个.bash_profile的路径但得到：
Following older related questions, I've tried adding this path to .bash_profile but got:
-bash :: /usr/local/lib/python2.7/site-packages/ipython：没有这样的文件或目录
-bash: :/usr/local/lib/python2.7/site-packages/ipython: No such file or directory
每当终端开始时。
更多信息：Anaconda安装了一个删除的El-Capitan 10.11.2，python 2.7。
Some more info: Anaconda installed an removed, El-Capitan 10.11.2, python 2.7.
任何帮助都将不胜感激！
Any help would be much appreciated!
编辑：向@cel请求添加了更多信息：
added some more info to @cel request:
echo $ PATH 给出：
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/git/bin:/Library/TeX/texbin:/Applications/Sublime Text.app/Contents/SharedSupport/bin
其中-a python 给出：
/ usr / local / bin / python 和 / usr / bin / python 。
编辑：添加 python -m pip install ipython 的输出到cel的请求：
added the output of python -m pip install ipython to cel's request:

推荐答案
在网上搜索bash：ipython：command not found出现了几次点击（包括这个问题），但它们并没有特别有用。从它的声音，你有 IPython ，安装了Python 包，但是 ipython - 它的包装/发射器 - 因任何原因而丢失。要检查是否是这种情况，请尝试运行：
Searching the web for "bash: ipython: command not found" turns up several hits (including this SO question), but they're not particularly helpful. From the sound of it, you have IPython, the Python package installed, but ipython—the wrapper/launcher for it—is missing for whatever reason. To check whether this is the case, try running:
% python -m IPython
Python 2.7.9 (default, Feb 10 2015, 03:28:08)
Type "copyright", "credits" or "license" for more information.
IPython 4.0.0 -- An enhanced Interactive Python.

如果这会带来IPython，那么你可能会尝试制作一个shell别名，因为上面链接的SO答案表明，即在shell的启动脚本中输入类似的内容： alias ipython ='python -m IPython'。或者，自己创建启动器脚本。对我来说，它存在于 / usr / local / bin / ipython 中，并包含以下内容：
If that brings up IPython, then you might try making a shell alias as the SO answer linked above suggests, i.e., put something like this in your shell's startup script: alias ipython='python -m IPython'. Or, create the launcher script yourself. For me, it lives in /usr/local/bin/ipython and contains the following:
#!/usr/local/opt/python/bin/python2.7
# -*- coding: utf-8 -*-
import re
import sys
from IPython import start_ipython
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
sys.exit(start_ipython())
希望这会有所帮助。 （如果确实如此，请考虑对其他SO 问题进行投票 ......）
Hope this helps. (If it does, please consider up-voting the other SO question as well...)
