如何在Windows上安装python-Levenshtein

Question

我看到之前有人问过关于在Python中安装Levenshtein的问题，但另一个用户建议我自己发个帖子，所以我就来了。

我在使用64位的Windows 8系统。当我尝试安装Levenshtein时，出现了以下错误。

C:\Python27\Lib\site-packages\python-Levenshtein-0.10.2>python setup.py install

有人告诉我需要安装setup-tools，我已经安装了。此外，

还需要从 http://www.microsoft.com/en-us/download/details.aspx?id=6506 下载vcsetup.exe并运行它。

等它完成后，打开你的命令提示符（command.exe）。

然后输入：easy_install python-Levenshtein（这假设你已经安装了setuptools）。

但是，当我输入“easy_install”时，出现了以下信息。我对这些话也有点困惑。我是不是应该指向setup.py文件？

C:\Python27\Lib\site-packages\python-Levenshtein-0.10.2>easy_install python-Leve
nshtein
'easy_install' is not recognized as an internal or external command,
operable program or batch file.

Answer 1

关于easy_install的问题，主要是因为你的 Python 脚本文件夹没有添加到 PATH 里。只需要把下面的内容加到 PATH 里：

 C:\Python27\Scripts

至于你最开始的问题，可以看看这个问题的回答。
