======================================================== 1 error in 1.24s ========================================================## 原因：
coveralls依赖了docopt模块，而docopt已经有6年没更新了，它并不支持高版本的Python
## 解决：
方案一：使用docopt-ng平替Resolve invalid escape sequence warnings by daugihao · Pull Request #507 · docopt/docopt · GitHub
python -m pip install docopt-ng方案二：手动修改docopt的源码，在字符串前加上r，如：
- name = re.findall('(<\S*?>)', source)[0]
+ name = re.findall(r'(<\S*?>)', source)[0]这篇关于coveralls使用pytest进行本地测试时报错SyntaxError: invalid escape sequence \S的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
