ipython：在OSX上找不到的命令

不久前我在OSX上使用brew和pip或easy_install安裝了python科學環境（numpy，scipy，matplotlib，pandas，ipython）（或者其中的2個，我沒有記得）。現在，如果嘗試運行IPython中，我得到：ipython：在OSX上找不到的命令

-> ipython 
-bash: ipython: command not found

然後我做：

-> sudo find . -iname "*ipython*"

./usr/local/lib/python2.7/site-packages/matplotlib/sphinxext/ipython_directive.pyc 
./usr/local/share/python/ipython

我很驚訝，沒有看到任何/ bin目錄。

然後我試圖重新安裝IPython的

-> pip install ipython 
Requirement already satisfied (use --upgrade to upgrade): ipython in /usr/local/lib/python2.7/site-packages 
Cleaning up...

這實在是令人困惑的。任何想法是受歡迎的。

你確定你調用的pip屬於Homebrew的Python嗎？從你的文件列表中看來，你已經在你的系統Python中安裝了'ipython'，所以它已經把可執行文件放到''/ usr/local/share/python''中。 – fjarri

創建您$HOME以下內容.pydistutils.cfg

[global] 
verbose=1 

[install] 
install-scripts=$HOME/bin 

[easy_install] 
install-scripts=$HOME/bin

運行

pip install -U --user --force ipython

看一看https://github.com/pypa/pip/issues/426

您的建議會導致錯誤：無法將用戶與前綴，exec_prefix/home或install_（plat）base組合在一起。我能夠使用這個http://stackoverflow.com/questions/4495120/combine-user-with-prefix-error-with-setup-py-install來更正它。現在ipython正常工作。 –

解決方法（至少對於IPython中）是將這些行添加到~/.pydistutils.cfg ： [install] install-data=/usr/local install-scripts=/usr/local/bin
