NameError: name 'retry' is not defined. Did you mean: 'repr'?

根据提供的引用内容，无法确定出现该错误的具体上下文和代码。但是，根据常见的情况，可能是在使用retry时出现了错误。retry是一个Scrapy中的重试机制，可以在请求失败时自动重试。如果没有正确导入retry模块或者没有正确使用retry函数，就会出现该错误。建议检查代码中是否正确导入了retry模块，并且是否正确使用了retry函数。如果还是无法解决问题，可以提供更多的上下文和代码，以便更好地帮助您解决问题。

这个错误提示是因为Python的ssl模块没有安装或者配置正确，造成pip无法连接到https协议的服务器。你可以尝试以下几种方法解决这个问题：

1. 安装ssl模块：可以通过命令行输入`pip install pyopenssl ndg-httpsclient pyasn1`来安装ssl模块，然后再次尝试安装heartpy。

2. 使用http协议：在pip安装命令中加上`--trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org`参数，强制使用http协议进行下载。

3. 更换pip源：将pip源更换为其他可用的源，例如清华大学的源。可以通过在命令行输入`pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple`来更换源。之后重新执行安装命令即可。

希望以上方法能够帮助你解决问题。

这是一个错误提示，它意味着你的 Python 环境缺少 SSL 模块，导致无法从 HTTPS URL 中获取数据。解决这个问题的方法是安装 SSL 模块。具体的安装方法可能因操作系统和 Python 版本而异，你可以尝试在命令行中输入以下命令来安装 SSL 模块：

- 如果你使用的是 Ubuntu 系统，可以尝试使用以下命令来安装 SSL 模块：sudo apt-get install libssl-dev
- 如果你使用的是 macOS 系统，可以尝试使用以下命令来安装 SSL 模块：brew install openssl
- 如果你使用的是 Windows 系统，可以尝试下载 OpenSSL 安装包并进行安装。安装包下载地址为：https://slproweb.com/download/Win64OpenSSL-1_1_1k.exe

安装完 SSL 模块后，你的 Python 环境就可以正常使用 HTTPS URL 了。
