英文:
db.sadd is not a function?
问题
I'm trying to run some Node.js examples from the Express GitHub repository at this link. For this specific example, I ran npm update and made sure that Redis in the root package.json is "redis": "^4.6.7". However, I'm encountering an error related to the sadd function not being present. I searched the Redis GitHub repository for sadd but couldn't find its function definition. Does anyone know what's happening or how to further debug this?
$ node index.js
/home/vboxuser/src/nr/express/examples/search/index.js:28
db.sadd('ferret', 'tobi');
^
TypeError: db.sadd is not a function

这个示例是不正确的。正确的函数名称是.sAdd或.SADD。我通常使用.sAdd，因为在代码中全大写感觉奇怪。我强烈鼓励您向他们发送一个拉取请求。
如果您遇到其他类似的问题，您可以在Node Redis README中找到几乎所有内容。
英文:
This example is incorrect. The correct function name is .sAdd or .SADD. I usually go with .sAdd as all caps feels weird in code. I would heartily encourage you to send them a PR.
If you run into other issues like this, you can find the pretty much everything in or off of the Node Redis README.
