python-2.7 - 使用 tools.run_flow() 在 Google Sheets API 教程中引发 SSLHandshake "certificate verify"错误

Question

我几乎一直在关注 Google 表格入门(使用 Python)。我已经让程序在我的 Mac 笔记本电脑上运行，但它失败了，因为我试图在 Windows 上运行它。到目前为止，我已经检查过我们没有在机器上启用防火墙。

下面是点击浏览器中弹出的身份验证提示后出现的错误。

Answer 1

我不太确定这是怎么发生的，因为我在 virtualenv 中工作，但在 httplib2 和 oauth2 的版本中存在依赖性问题。卸载后重新安装，出现两个库不兼容的错误。

执行 pip freeze 显示我有 httplib2==0.8 但 oauth2client 需要 httplib2=>0.9。

这已通过执行 pip install --upgrade httplib2 解决。
