安装rdflib时找不到路径

Question

当我设置的时候，我收到了：

C:\Python27>python Lib\site-packages\rdflib-master\setup.py
Traceback (most recent call last):
    File "Lib\site-packages\rdflib-master\setup.py", line 64, in <module>
        version = find_version('rdflib/__init__.py')
    File "Lib\site-packages\rdflib-master\setup.py", line 59, in find_version
        for line in open(filename):
IOError: [Errno 2] No such file or directory: 'rdflib/__init__.py'

文件是存在的，我也试着把包的路径加到PYTHONPATH里，但还是不行。

于是我尝试使用ez_setup.py，但它在某个网址上出错，显示404（下面有详细信息）。

我也搜索了一些通用的安装建议：我找到了本科和研究生的内容，但没有什么能帮到我。

把源代码放到 Lib\site-packages 这个地方听起来有点奇怪，但如果你想从源代码安装的话，你需要在源代码的文件夹里运行 setup.py 这个文件。它会报错说 rdflib/__init__.py 这个文件不存在，因为确实没有这个文件：要注意，这里的路径是相对的。

我们需要更多的信息，抱歉哦。你用的是哪个版本的RDFLib？你是怎么尝试安装的？能把完整的错误信息发给我们吗？

最好的方法是使用“pip”来安装，具体可以参考这个链接：http://www.pip-installer.org/en/1.3.X/installing.html

然后执行下面的命令：

pip install rdflib

这样就能安装最新的RDFLib 3.2.X版本了！
