python bootstrap.py文件无法成功打开

Question

我按照此处的说明操作：https://github.com/hackable-devices/makerbot_tools 安装makerbot驱动程序。

我接受了引导项目的指令。我跑的时候

python bootstrap.py

我的回答是：

Downloading https://pypi.python.org/packages/source/s/setuptools/setuptools-0.9.6.tar.gz
Extracting in c:\users\kevin lee jr\appdata\local\temp\tmpsd6_ga
Traceback (most recent call last):
    File "bootstrap.py", line 92 in <module>
        ez['use_setuptools'](**setup_args)
    File "<string>", line 116, in use_setuptools
    File "<string>", line 101, in _do_download
    File "<string>", line 73, in _build_egg
    File "C:\Python27\lib\tarfile.py", line 1665, in open
        raise ReadError("file could not be opened successfully")
tarfile.ReadError: file could not be opened successfully

知道打开这些文件有什么问题吗？我安装了tarfile模块。
