pipenv lock .... Timing out

[mikenew]

I had pipenv working fine then my mac crashed and when i started terminal session again the lock file was missing and pipenv run ... did not work

Tried pipenv lock and over a dozen tries got time out error each time as below

=== Update 10th Jan
This problem occurs intermittently. I uninstalled a few libraries from the pip file, installed one and pipenv lock now works on my Mac .... deployed the changes to AWS Ubuntu and now get the same timeout error on the Pipfile that works on my mac ... see comments
END UDPATE ====

Describe your environment

1. OS Type: Mac
2. Python version: 2.7.10
3. Pipenv version: 8.2.7

Expected result

Successful lock file generated

Actual result

Time out error

I uninstalled pipenv and reinstalled it ... ran pip lock and had a problem in the pip file so I deleted a line ... ran pip lock again and got the same timeout error as above

The new pipfile is

`[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true

[requires]

python_version = "3.6"

[packages]

requests = ""
"pathlib2" = ""

OK more is unfolding ...

I tried running the app and got an error library not found when the module had been installed for months and is in the Pipfile.

So I installed it again and the pipfile lock worked !

then I tried running the app again and got another library (pandas) not found ... so I tried installing that and the lock failed ....

Finally I did a pipenv install and got the following error

pipenv install
Pipfile.lock not found, creating…

I uninstalled docker - still same problem

I uninstalled trading-ig and it all works

[kennethreitz]

this looks to be an HTTP error, potentially with your network

[kurianbenoy]

@kennethreitz , is there an make over for this http error like increasing default-timeout period as in pip ?

So that pipenv --timeout=100000 lock will work
