Not all of the examples are meant to work without modification.
The version suffix is only meant to indicate an alternate version
of the same example. e.g. custom-headers-v2.js is meant to be used
with the latest version of Cloudscraper, not Cloudscraper v2.0.0.
If you've noticed for some reason that an example is outdated and/or misleading, please send a PR to correct it.
In fact, updating or adding examples is a great way to contribute!
If you don't have the time to send a PR, please consider opening an issue instead.
