The local lnmp virtual machine environment is also an lnmp environment, but the online environment is case sensitive.

The local lnmp virtual machine environment is also the online lnmp environment, but the online environment is case-sensitive. the local environment is also the linux Virtual Machine environment, but many times the size is wrong, and it is also executed smoothly.
After the synchronization is updated to the production site, it is very strictly differentiated. what is the common cause?
Otherwise, local debugging is meaningless.

This is a problem with your VM!

The debugging environment should be as consistent as possible with the production environment, unless you know the difference between the two and can avoid the consequences of the difference

Linux is case sensitive. it makes no sense.

Linux systems are case sensitive.
However, your linux virtual machine environment is case insensitive.
Are you saying you have a problem with your VM?

Linux is case sensitive. it makes no sense. Yes, I am also a linux environment ..~~ This problem can only be found later.
