AssertionError: Egg-link .. does not match installed location of ReviewBoard (at /…)

问题 AssertionError: Egg-link /home/daniel/other-rb/reviewboard does not match installed location of ReviewBoard (at /home/daniel/reviewboard) I believe this was caused by me installing a package at an additional location using the same virtualenv. How can I fix this problem? I'm guessing I need to redirect the Egg-link to match the installed location? Stack trace: (reviewboard-3.0) daniel@beepboop ~/reviewboard $ ./setup.py develop /home/daniel/envs/reviewboard-3.0/local/lib/python2.7/site

问题 I know I can install with $ pip install -e git+https://git.repo/some_pkg#egg=SomePackage but -- when I'm trying to use somebody else's package -- how do I determine what the name of the egg is? 回答1: Look at the git repo, find the setup.py file in the root and find what is passed to the name keyword in the setup() function call. For example, the Pyramid setup.py has: setup(name='pyramid', so you'd use: $ pip install -e git+https://github.com/Pylons/pyramid.git#egg=pyramid 来源： https:/

问题 About the only reason I can think of to distribute a python package as an egg is so that you can not include the .py files with your package (and only include .pyc files, which is a dubious way to protect your code anyway). Aside from that, I can't really think of any reason to upload a package as an egg rather than an sdist. In fact, pip doesn't even support eggs. Is there any real reason to use an egg rather than an sdist? 回答1: One reason: eggs can include compiled C extension modules so

2 Egg Problem 继续我们的推理问题之旅，今天我们要对付的是一个Google的面试题：Two Egg Problem. 我们开始吧！ No.2 Google Interview Puzzle : 2 Egg Problem * You are given 2 eggs. * You have access to a 100-storey building. * Eggs can be very hard or very fragile means it may break if dropped from the first floor or may not even break if dropped from 100th floor. Both eggs are identical. * You need to figure out the highest floor of a 100-storey building an egg can be dropped without breaking. Now the question is how many drops you need to make. You are allowed to break 2 eggs in the process 分析与解答： 题目要求试的最大次数最小。首先，讨论两个比较trivial的方案。

How to include and use .eggs/pkg_resources within a project directory targeting python 2.5.1

由 旧时模样 提交于 2019-12-07 14:37:33
问题 I have python .egg files that are stored in a relative location to some .py code. The problem is, I am targeting python 2.5.1 computers which require my project be self contained in a folder (hundreds of thousands of OLPC XO 8.2.1 release laptops running Sugar). This means I cannot just ./ez_install to perform a system-wide setuptools/pkg_resources installation. Example directory structure: My Application/ My Application/library1.egg My Application/libs/library2.egg My Application/test.py I
