未找到安装rdflib的路径

Question

当我设置时，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'

文件就在那里，我尝试将包路径添加到PYTHONPATH；没有成功。

所以我试着使用ez_setup.py，但它在一些url上显示为404 (如下所示)。

我还搜索了一般的安装建议:我找到了pre-K和postgrad，但没有对我有帮助的。

Answer 1

恐怕我们需要更多的信息。哪个版本的RDFLib？正在尝试如何安装？我们能得到完整的错误信息吗？

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！

将源代码放入Lib\site-packages中是一个奇怪的想法，但如果您想要从源代码安装，则需要从源代码目录调用setup.py。它会抱怨rdflib/__init__.py不存在，因为它不存在:请注意路径是相对的。
