我最近删除了Anaconda并用brew重新安装了python.我按照这些说明安装了所有东西.
Python工作得很好,到目前为止我测试的所有软件包都可以工作.我已经安装了ipython,但尝试从终端启动它会给出:
-bash:ipython:找不到命令
我找到了安装位置:
/usr/local/lib/python2.7/site-packages/ipython
在更早的相关问题之后,我尝试将此路径添加到.bash_profile但是得到了:
-bash :: /usr/local/lib/python2.7/site-packages/ipython:没有这样的文件或目录
终端启动时.
更多信息:Anaconda安装了一个删除的El-Capitan 10.11.2,python 2.7.
任何帮助将非常感激!
编辑:为@cel请求添加了更多信息:
echo $PATH 得到:
/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
which -a python给出:
/usr/local/bin/python和/usr/bin/python.
编辑:添加了python -m pip install ipythoncel的请求的输出:

Error in aeqSurv(Y) :
aeqSurv exception, an interval has effective length 0
除了源代码，我在网上找不到任何对这个错误的引用。将不胜感激有关如何处理此异常的任何想法。
