jieba库安装我和你干上了

最近老是遇到第三方库安装不上。比如jieba库。

1. jieba库能干嘛

jieba“结巴”中文分词：做最好的 Python 中文分词组件

“Jieba” (Chinese for “to stutter”) Chinese text segmentation: built to be the best Python Chinese word segmentation module.

完整文档见 README.md

GitHub: https://github.com/fxsjy/jieba

2. 特点

• 支持三种分词模式：
  • 精确模式，试图将句子最精确地切开，适合文本分析；
  • 全模式，把句子中所有的可以成词的词语都扫描出来, 速度非常快，但是不能解决歧义；
  • 搜索引擎模式，在精确模式的基础上，对长词再次切分，提高召回率，适合用于搜索引擎分词。
• 支持繁体分词
• 支持自定义词典
• MIT 授权协议
  在线演示： http://jiebademo.ap01.aws.af.cm/

3. 安装说明

代码对 Python 2/3 均兼容。

• 全自动安装： easy_install jieba 或者 pip install jieba / pip3 install jieba
• 半自动安装：先下载 https://pypi.python.org/pypi/jieba/ ，解压后运行 python setup.py install
• 手动安装：将 jieba 目录放置于当前目录或者 site-packages 目录，通过 import jieba 来引用

4. 动手环节

使用命令：

pip3 install jieba

问题来了，我信你个鬼，就是匹配不到 。
呵呵，我采用 半自动安装的方式。

4.1 下载jieba离线包

从官网按照下图下图即可。

4.2 解压并安装

解压文件jieba-0.42.1.tar.gz之后，并进入解压目录。

4.3 查看jiaba版本，检验是否安装成功

执行命令

pip show jieba

效果如下：

D:\Python38-32\jieba-0.42.1\jieba-0.42.1>pip show jieba

也可以进入python交互命令使用import jieba校验是否安装成功，我咋就喜欢用pip show jieba呢，嘻嘻。。

5.结语

没啥说的了，动手实操都在上边了，反正最近我是和pip install 库名 干上了，直接安装都不行。

如果要看大佬的爬虫案例 ，去搜msdn一个叫“不正经的kimol君”的大佬吧；
或者微信公众号“Python干货铺子”的大佬吧。
