Fabric does not pass the environment to a local shell like Invoke does

Consider this task definition, saved as both fabfile.py and tasks.py:

from invoke import task

@task
def make(c):
    c.run('env')

fab make outputs:

PWD=/tmp
SHLVL=1
_=/usr/bin/env

inv make outputs:

LC_ALL=en_US.UTF-8
NVM_DIR=/home/justinas/.nvm
LC_MEASUREMENT=en_US.UTF-8
LC_PAPER=en_US.UTF-8
LC_MONETARY=en_US.UTF-8
<...> (lots of stuff in my environment)

I initially found this when trying to use fpm which checks the PATH variable to check that the executables it requires to function exist:

from invoke import task

@task
def make(c):
    c.run('fpm -s dir -t rpm -C dist --name somename .')

This works with invoke, but not with fab.

justinas@js:/tmp$ fab make
{:timestamp=>"2018-05-11T13:11:26.218874+0300", :message=>"Need executable 'rpmbuild' to convert dir to rpm", :level=>:error}
justinas@js:/tmp$ inv make
{:timestamp=>"2018-05-11T13:11:29.967762+0300", :message=>"Created package", :path=>"somename-1.0-1.x86_64.rpm"}

@justinas I ended up using run from invoke for local tasks, I import it like this:

from invoke import run as local

@task
def test(c):
    local('ls')

I just ran into this as well. I was doing c.run('make build') and none of my ENV pulled through (specifically GOPATH which caused the build to fail). Adding the replace_env=False fixed it.

Edit: I see according to the docs:

run.replace_env: True, instead of False, so that remote commands run with a ‘clean’, empty environment instead of inheriting a copy of the current process’ environment.

It was just a bit confusing to me since I was trying to run a local command.
