我html.render()从requests_html图书馆跑。它正在尝试安装 chromium，但出现错误
我已经尝试过pip install --upgrade certifi使用和不使用sudo
并得到：Requirement already up-to-date: certifi in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (2019.6.16)
我也尝试运行/Applications/Python\ 3.6/Install\ Certificates command并得到：
-- pip install --upgrade certifi
Requirement already up-to-date: certifi in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (2019.6.16)
-- removing any existing file or link
-- creating symlink to certifi certificate bundle
-- setting permissions
-- update complete
logout
