在 Ubuntu 14.04 上为 Python 3 安装 Trepan 调试器

Question

我正在使用带有 Python 版本 2.7.6 的 Ubuntu 14.04。我最近使用pyenv 将 Python 版本 3.4.2 与系统 Python 并排安装。现在我想测试一些 Python 3 的调试器，我从python3-trepan project page 下载了trepan-0.2.8-py3.3.egg。

然后我运行pyenv global 3.4.2 和easy_install trepan-0.2.8-py3.3.egg，这给了我以下错误：

更新：

问题似乎与使用pyenv 安装 Python 3 无关：我尝试了以下方法：

• 已禁用pyenv
• sudo apt-get install python3 python
• sudo apt-get install python3-setuptools
• sudo easy_install-3.4 trepan-0.2.8-py3.3.egg

这给了我同样的错误：

你可以看看https://askubuntu.com/questions/95037/what-is-the-best-way-to-install-python-packages或https://askubuntu.com/questions/350437/installing-python-modules-on-ubuntu或Installing python modules on Ubuntu

这可能会解决问题。希望对您有所帮助。

Answer 2

我还没有测试过，但是维护者@rocky 推荐这个安装：

pip3 install trepan3k

旧：

使用此命令安装：

pip3 install -e git+https://github.com/rocky/python3-trepan/#egg=trepan

我认为当前的 tarball/eggs 已损坏

Answer 3

从 Trepan 0.4.2 开始（在撰写本文时，我们处于 0.4.7），pip 问题得到了解决。不过……

您正在使用 pyenv，但请注意，在没有它的 Ubuntu 14.04 上，您可能需要使用 pip3 而不是 pip。在 pyenv 之外，我认为默认 pip 为 Python2 的 pip。另见this link。

唉，还有一个奇怪的地方。当轮子不可用时（如版本 0.4.7 之前的情况），pip 使用源 tarball 来安装而不是鸡蛋。然而，Python 2 和 Python 3 的源代码必然是不同的，尝试将它们组合成一个源代码太困难了。

所以，我已经开始将车轮格式文件放在 pypi.org 上，我希望这也能解决未来类似的问题。
