About “pip install .”

[ooooppps]

while installing deepmd from source code and running line "pip install .", the process aborted for servers cannot connect to the Internet. Terminal seems to run a "pip install" line with option"--ignore-installed". On this occasion, how can i do to make it run without "--ignored-installed"?
