usage: go env[-json][-u][-w][var ...]
Env prints Go environment information.
By default env prints information as a shell script
(on Windows, a batch file). If one or more variable
names is given as arguments, env prints the value of
each named variable on its own line.
The -json flag prints the environment in JSON format
instead of as a shell script.
The -u flag requires one or more arguments and unsets
the default setting for the named environment variables,
if one has been set with 'go env -w'.
The -w flag requires one or more arguments of the
form NAME=VALUE and changes the default settings
of the named environment variables to the given values.
For more about environment variables, see 'go help environment'.
Print the value of a specific environment variable
C:\Users\love1>go env GOROOT
C:\Program Files\Go
Modify the value of a variable go env -w GO111MODULE=off (the modification is permanent)
go env -u variable name 1, change name 2... restore the default configuration of these environment variables
