macos - ipython:在 OSX 上找不到命令

Question

我不久前在 OSX 上使用 brew 和 pip 或 easy_install(或其中的 2 个，我不记得了)安装了 python 科学环境(numpy、scipy、matplotlib、pandas、ipython)。现在，如果尝试运行 ipython，我会得到:

-> ipython
-bash: ipython: command not found

然后我做了:

-> sudo find . -iname "*ipython*"
Password:
find: ./dev/fd/3: Not a directory
find: ./dev/fd/4: Not a directory

我很惊讶没有看到任何/bin 目录。

然后我尝试重新安装ipython

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

这真是令人费解。欢迎任何想法。

在你的$HOME下面的内容中创建.pydistutils.cfg

[global]
verbose=1

[install]
install-scripts=$HOME/bin

[easy_install]
install-scripts=$HOME/bin

运行

pip install -U --user --force ipython
