zc.buildout中的IPython笔记本不使用egg路径 [英] IPython notebook in zc.buildout not using eggs path

问题描述

我用zc.buildout构建了一个包含IPython脚本的环境。

I've build an environment with zc.buildout including IPython script.

我的问题很简单：

• 如果我在控制台中启动IPython，一切正常，我在sys.path中获取所有鸡蛋

• if I launch IPython in console, everything is OK and I get all my eggs in sys.path

但如果我启动IPython笔记本，我只会得到默认系统路径。

but if I launch IPython notebook, I only get default system path.

有没有办法包括我的所有鸡蛋在启动笔记本时？

Is there any way to include all my eggs while starting notebook?

问候，

Thierry

推荐答案

所以，我想在笔记本电脑启动过程中某个进程是分叉的，这意味着sys.path将被重置并且buildout的技巧将无济于事。

So, I guess somewhere in the notebook startup a process is forked, which means sys.path will get reset and buildout's tricks won't help.

我解决了以下问题，虽然它有点脏：

I solved the problems as follows, although it's a bit dirty:

1. 创建一个入口点如下：

1. Create an entry point as follows:

setup(...
      entry_points = {
          'console_scripts': ['ipython = <yourpackage>.ipython:main']
      })

将以下内容放在/yython.py中：

Put the following in /ipython.py:

from IPython.frontend.terminal.ipapp import launch_new_instance
import os
import sys

def main():
    os.environ['PYTHONPATH']=':'.join(sys.path)
    sys.exit(launch_new_instance())

现在，运行 bin / ipython notebook 将为您提供您期望的sys.path。

Now, running bin/ipython notebook will give you the sys.path you expect.
