我正在使用Ubuntu 14.04和Python 2.7.6版。我最近使用pyenv与系统Python并排安装了Python 3.4.2版。现在我想测试一些Python 3的调试器，然后从python3-trepan project page下载了trepan-0.2.8-py3.3.egg。
然后我运行了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：我尝试了以下内容：
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：

我还没有测试过，但维护者@rocky建议安装：
pip3 install trepan3k
<强> OLD ：
使用此命令安装：
pip3 install -e git+https://github.com/rocky/python3-trepan/#egg=trepan
我认为目前的tarball /鸡蛋已经坏了
答案 1 :(得分：1)
从trepan 0.4.2开始（在撰写本文时我们处于0.4.7），解决了点子问题。但是......
您正在使用pyenv，但请注意，在没有它的情况下，您可能需要使用 pip3 而不是 pip 。在pyenv之外我认为默认 pip 到Python2的 pip 。另请参阅this link。
唉，还有另一种奇怪之处。当一个轮子不可用时（就像版本0.4.7之前的情况一样），pip使用源tarball来安装而不是一个鸡蛋。但是，Python 2与Python 3的源代码必然不同，尝试将这些代码组合成一个源代码太难了。所以，我已经开始在pypi.org上放置wheel格式文件，我希望这也将在未来解决这样的问题。
