在Python 3.6 (Windows 8)中安装PGU库时出错

Question

我正在尝试从Power Shell以不同的方式安装Windows 8中的PGU库，并在这个网页和其他网页中进行了搜索，但都没有成功。我也已经在this other question中尝试过答案了。这是在PowerShell中显示的内容：

PS C:\Users\Núria> pip install pgu-0.18.zip

During handling of the above exception, another exception occurred:

我不明白这个错误是从哪里来的，也不知道如何解决它。欢迎任何帮助！

将此代码添加到setup.py文件中：

str = unicode(str, errors='ignore')

此外，如果在您尝试安装模块的文件夹中存在requirements.txt文件，请先执行以下操作：

pip install requirements.txt
