第一，你的系统需要安装jieba类库， pip install jieba
第二，接下来修改sphinx的conf.py文件，为项目设置为中文的搜索配置。
# Language to be used for generating the HTML full-text search index. # Sphinx supports the following languages: # 'da', 'de', 'en', 'es', 'fi', 'fr', 'hu', 'it', 'ja' # 'nl', 'no', 'pt', 'ro', 'ru', 'sv', 'tr', 'zh' html_search_language = 'zh'
第三，可选配置
# A dictionary with options for the search language support, empty by default.
# 'ja' uses this config value.
# 'zh' user can custom change `jieba` dictionary path.
# html_search_options = {'dict': '/usr/lib/jieba.txt'} # 根据需要设置jieba的词典路径
第四，接下来重新编译生成文档。make html
