无法安装 Whoosh Alchemy

Question

我好像怎么也装不上whoosh alchemy。参考链接是：http://pythonhosted.org/Flask-WhooshAlchemy/。总之，我在跟着这个教程：http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world，到现在要安装whoosh-alchemy的部分。

我输入了这三条命令中的任何一条：

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

但是我遇到的错误是：

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()],
AttributeError: '_io.TextIOWrapper' object has no attribute 'xreadlines'
Complete output from command python setup.py egg_info:

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

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

我完全不知道该怎么解决这个问题……我试着在网上搜索，但一点运气都没有。也许我的搜索能力真的很差。非常感谢任何帮助。

我在Flask-WhooshAlchemy的GitHub上发现了这个请求，里面提到因为xreadlines的调用导致pip安装失败，就像你错误日志里显示的那样。你可以尝试直接从GitHub安装，因为那个请求已经合并了。

下面是安装的命令 - pip install git+https://github.com/gyllstromk/Flask-WhooshAlchemy.git
