Assumptions about Linux software packages

For more information about the Linux software package-general Linux technology-Linux technology and application, see the following. Although I have a little understanding of Linux, I still encounter various software dependencies when installing software packages, which is often troublesome to solve.

So I thought: why don't a software package all the dependent environments it needs?

You may say that some dependent environment packages already exist in the system. This package is unnecessary, can there be a mechanism to automatically compare the dependent environment of the system to the dependent environment in the installation package (or even compare the Environment version that needs to be dependent on, if it meets or is compatible, use the system dependent environment ), this simplifies software installation and facilitates the promotion of Linux to common users.
