I found some bug when i use ‘sparse submit’

[elfgzp]

When i run ‘sparse submit’.
I got an error
Fatal error: put() encountered an exception while uploading 'virtualenvs/wordcount.txt'
so i set a breakpoint at
update_virtualenv.py line 52

for requirements_path in requirements_paths:
    puts("Uploading {} to temporary file.".format(requirements_path))
    temp_req = run("mktemp /tmp/streamparse_requirements-XXXXXXXXX.txt") # this line
    put(requirements_path, temp_req)

I got the value of temp_req, it was
Docker machine "boot2docker-vm" does not exist. Use "docker-machine ls" to list machines. Use "docker-machine create" to add a new one. /tmp/streamparse_requirements-XXXXXXXXX.txt /bin/bash: shell_session_update: command not found
It contain some error info.

Then i set the value temp_req= '/tmp/streamparse_requirements-XXXXXXXXX.txt'.

It work!!

By the way,
When i got the errorFatal error: put() encountered an exception while uploading 'virtualenvs/wordcount.txt'
I must remove the '/tmp/streamparse_requirements-XXXXXXXXX.txt' file before i run sparse submit.
