无法在virtualenv

Question

在我的根项目文件夹中，我使用以下命令为python 3.4创建了一个虚拟环境：

$ virtualenv -p /Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4 venv
$ source venv/bin/activate

现在我想为这个项目安装一些带有pip的软件包，我这样做：

$ venv/bin/pip install html

我收到以下错误（完全追溯，除了我已用＆＃39; ...＆＃39;替换路径）：

Collecting html
  Using cached html-1.16.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<frozen importlib._bootstrap>", line 2218, in _find_and_load_unlocked
    AttributeError: 'module' object has no attribute '__path__'

    During handling of the above exception, another exception occurred:

注意我可以在没有问题的情况下安装这个软件包，因为我的mac上的默认版本是python 2.7.5。

我要安装的软件包是这样的： https://pypi.python.org/pypi/html/1.16

该软件包已过时，与当前的包装工具不兼容，其最新版本已超过8年。我真的怀疑这么久以前发布的软件包是否仍可用于最新的python。
