python - 无法安装 whoosh alchemy

Question

我似乎一辈子都无法安装 whoosh alchemy。引用:http://pythonhosted.org/Flask-WhooshAlchemy/ .不管怎样，我在关注http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world在我尝试安装 whoosh-alchemy 的部分。

我正在输入这 3 个中的任何一个

flask\Scripts\pip install flask-whooshalchemy==0.55a 
flask\Scripts\pip install flask-whooshalchemy
flask\Scripts\pip install flask-whooshalchemy==0.55

我得到的错误如下:

Downloading/unpacking flask-whooshalchemy
    Downloading Flask-WhooshAlchemy-0.55.tar.gz
    Running setup.py (path:C:\users\ray\microblog\flask\build\flask-whooshalchemy\setup.py) egg_info for package flask-whooshalchemy
Traceback (most recent call last):

    'requirements.txt')).xreadlines()],

Complete output from command python setup.py egg_info:

'requirements.txt')).xreadlines()],

 AttributeError: '_io.TextIOWrapper' object has no attribute 'xreadlines'

我完全不知道如何解决这个问题......我正在尝试用谷歌搜索这个但没有找到任何运气。也许我的 google-fu 太糟糕了。非常感谢任何帮助。

我找到了 this pull request在 Flask-WhooshAlchemy 的 github 上，它讨论了由于 xreadlines 调用而导致的 pip 安装失败，就像在您的错误日志中一样。尝试直接从已合并该拉取请求的 github 安装它。

这是执行此操作的命令 - pip install git+https://github.com/gyllstromk/Flask-WhooshAlchemy.git
