You are running Python 2 code on Python 3. In Python 3, the module has been renamed to http.client.
您正在 Python 3 上运行 Python 2 代码。在 Python 3 中，模块已重命名为http.client.
You could try to run the 2to3toolon your code, and try to have it translated automatically. References to httplibwill automatically be rewritten to use http.clientinstead.
您可以尝试在您的代码上运行该2to3工具，并尝试使其自动翻译。对的引用httplib将被自动重写以http.client代替使用。

I had this issue when I was trying to make my Docker container smaller. It was because I'd installed Python 2.7 with:
当我试图让我的 Docker 容器更小时，我遇到了这个问题。这是因为我安装了 Python 2.7：
apt-get install -y --no-install-recommends python
And I should not have included the --no-install-recommendsflag:
而且我不应该包含--no-install-recommends标志：
apt-get install -y python
