找不到安装rdflib的路径

Question

设置后，我得到：

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'

该文件在那里，我尝试将包路径添加到PYTHONPATH。 没运气。

因此，我尝试使用ez_setup.py，但这使某些URL令人窒息，使其获得404（下面的跟踪）。

我还搜索了常规安装建议：我找到了pre-K和postgrad，但没有任何帮助。

Answer 1

恐怕我们需要更多信息。 哪个版本的RDFLib？ 如何尝试安装？ 我们可以得到完整的错误消息吗？

最好的方法是使用“ pip”，以某种方式安装它： http : //www.pip-installer.org/en/1.3.X/installing.html

然后做

pip install rdflib

这将安装最新的RDFLib 3.2.X！

将源放入Lib\\site-packages是一个奇怪的想法，但是如果要从源安装，则需要从源目录调用setup.py 。 它抱怨rdflib/__init__.py不存在，因为它不存在：请注意，该路径是相对的。
