在Ubuntu14.04上安装用于Python 3的透视图调试器

Question

我在Python版本2.7.6中使用Ubuntu14.04。我最近使用pyenv安装了PythonVersion3.4.2与系统Python并行。现在，我想测试一下Python3的一些调试器，并从python3 3-吐露聚糖项目页面下载了python3 3-吐露聚糖项目页面。

然后运行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：

这个问题似乎与使用pyenv安装Python3无关:我尝试了以下方法：

• 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：

Answer 1

我还没有对其进行测试，但维护人员@rocky建议安装如下：

pip3 install trepan3k

老

使用以下命令安装：

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

我想现在的油球/鸡蛋坏了。

Answer 2

从吐鲁番0.4.2开始(在本文中我们是0.4.7)，讨论了pip问题。然而..。

您使用的是pyenv，但是请注意，在Ubuntu14.04上，如果不使用它，您可能需要使用pip3而不是pip。在pyenv之外，我认为默认pip为Python2 2的pip。另见此链接。

唉，还有另一个奇怪的地方。当车轮不可用时(如0.4.7版之前的情况)，pip使用源tarball来安装，而不是从鸡蛋中安装。然而，Python 2与Python 3的源代码必然是不同的，很难将它们合并到一个源代码中。

因此，我已经开始在pypi.org上放置轮式格式文件，我希望这也能在将来解决这样的问题。

您可以看看https://askubuntu.com/questions/95037/what-is-the-best-way-to-install-python-packages、https://askubuntu.com/questions/350437/installing-python-modules-on-ubuntu或在Ubuntu上安装python模块

这也许能解决问题。希望能帮上忙。
