.zplug/bin/install conflict with system /usr/bin/install

[TheRainstorm]

Describe the bug
I am compiling the mosh(a ssh client for mobile network) program from source code using the traditional config + make process. During the config process, the system's install program (/usr/bin/install -c) is required. However, zplug also has an install program ($HOME/.zplug/bin/install), which causes the config to call zplug's install program, resulting in a failure to run.
One solution is to run echo $PATH, manually delete $HOME/.zplug/bin/, and then reset the PATH environment variable.
Although this cannot be considered a bug, I think it is not ideal to conflict with the system's default program. Perhaps zplug can limit its install to its own use?

To Reproduce
Steps to reproduce the behavior:
run which install, it print zplug's install rather than system's.

Expected behavior
zplug don't export its install program to PATH
