[Memo] HTML5 Manifest file Application Cache Error event: Manifest fetch failed (-1) error
Many places on the Web say that the content type of the manifest file is incorrect, or that the file format is incorrect, etc. After debugging, it turns out that this error can also occur if the file is not accessible (e.g., the server is down).
Solution to (ERROR: Failed to build gem native extension.) encountered when updating pod
sudo gem install -n /usr/local/bin cocoapods
Normally, if you execute the command above, you can upgrade directly. If you upgrade successfully, everything will be fine.
On the contrary, encounter the following upgrade failed!
➜ Ruby: sudo gem install -n /usr/local/bin cocoapods

This upgrade problem has been plaguing for several days. It may be that the ruby version is incompatible with the latest POD version. Therefore, Ruby must be upgraded before pod can be successfully upgraded.
The method is found on StackOverflow, but of course there are some other exception issues that need to be resolved during installation (by default you have xcode-select installed)
1. Install RVM
curl -L https://get.rvm.io | bash -s stable
If the installation is successful and the following prompts appear, you can proceed directly to step 2
Upgrade of RVM in /Users/mengshun/.rvm/ is complete.
Thanks for installing RVM 🙏

If you still report 443 errors, wait for a while and try again (I tried 3 times myself).

Forbidden (403) CSRF verification failed. Request aborted. – Django
How to solve the cross-domain problem of Django?
please see this article, very detailed: https://pypi.org/project/django-cors-headers/

The above is due to the CSRF problem, how to solve?
Two ways:
Top: comment out CsrfViewMiddleware as shown, but
is not recommended
Second: add the annotation @csrf_exempt
to the interface view
The above two methods do solve 403 errors.
However, according to a lot of information, the approach is that the front end first USES get request to specify the interface, and then the server generates get_token(request) to return to the front end. The front end carries csrftoken returned when requesting the interface, which will verify whether the cookie is consistent…
But they all tried in vain…
