pipenv fails to install all my packages, and then installs all of them

Hi, it might be something that I do not understand or so. I have 2 sources specified and none of them is official pypi, but mirrors, so here is my Pipfile:

[[source]]

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


[[source]]

url = "https://company/api/pypi/pypi-local/simple"
verify_ssl = true
name = "pypi-local"


[packages]

cachetools = "==2.0.1"
click = "==6.2"
data-object = "==1.2.1"
flask-cache = "==0.13.1"
flask-classy = "==0.6.10"
flask-humanize = "==0.3.0"
flask-migrate = "==2.1.1"
flask-oauthlib = "==0.9.4"
flask-sqlalchemy = "==2.3.2"
flask-wtf = "==0.14.2"
flask = "==0.12.2"
huey = "==1.6.0"
pendulum = "==1.4.0"
pyyaml = "==3.12"
redis = "==2.10.6"
requests = "==2.18.4"
requests-cache = "==0.4.13"
sqlalchemy = "==1.2.1"
whitenoise = "==3.3.1"
gunicorn = "==19.7.1"


[dev-packages]

ipdb = "*"
ipython = "*"
flask-shell-ipython = "*"
coverage = "*"
flake8 = "*"
flask-debugtoolbar = "*"

Describe your environment

1. OS Type Ubuntu
2. Python version: $ python -V Python 3.6.1
3. Pipenv version: $ pipenv --version pipenv, version 9.0.3

Expected result

All packages installed immediatly.

Steps to replicate

pipenv install --system Please also note, that pipenv is installing click==6.7 despite specifying 6.2 version.

closing since they are successful in the end — we’ll need much more information in order to replicate

Hi @jacekjab sorry you are running into this – the initial failure isn’t actually a bug, per se, I’m guessing it is related to concurrent installs from a non-pypi repository. They initially failed and then fell back to sequential installation. As far as the click installation, you will need to provide the full context of the command you ran, your $PATH, the output of env, that stuff would help

so the issue here is just that you are installing a bunch of VCS dependencies without using editable = true – many thanks @hjwp for the reproduction case

I believe I have a fix for this, although for the specific case you provided there will always be a single failure that will have to get pushed off till the end due to an editable dependency that needs to be installed after another dependency (you can avoid this with --sequential or by making the failing dependency editable)

Hi @techalchemy, thank you and you’re right, it’s due to some sort of conflicts related to the concurrent installation. However, making those dependencies editable didn’t solve the issue for me.

For people TL;DR, just add --sequential to your installation command, such as one of the following lines:

pipenv install --sequential

pipenv install --sequential -e .

pipenv sync --sequential
