Use private devpi server with pipenv

Question

I can install my packages with pip , using a private, local devpi server. The corresponding configuration is:

[global]
index_url = http://mydevpi.mine/root/pypi/+simple/

[search]
index = http://mydevpi.mine/root/pypi/

[install]
trusted-host = mydevpi.mine

Installing then with pip is straightforward:

pip install -r requirements.txt

But doing the same with pipenv does not seem to work. This works, but is not using my local devpi :

[[source]]
url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

And this does not work:

[[source]]

url = "http://devpi.dgv/root/pypi/+simple/"
verify_ssl = true
name = "pypi"

How can I tell pipenv to use another url for pypi ?

Answer 1

Examples provided assume default install of pypi server.

Method1: Pipfile

[[source]]
url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[[source]]
url = "http://localhost:8080"
verify_ssl = false
name = "home"

[dev-packages]

[packages]
requests = {version="*", index="home"}
beautifulsoup4 = {version="*", index="home"}
pandas = "*"

Method2: Commandline

$ pipenv install --pypi-mirror http://localhost:8080

$ pipenv update --pypi-mirror http://localhost:8080

$ pipenv sync --pypi-mirror http://localhost:8080

$ pipenv lock --pypi-mirror http://localhost:8080

$ pipenv uninstall --pypi-mirror http://localhost:8080

Method3: Environment Variable

export PIPENV_PYPI_MIRROR=http://localhost:8080

Answer 2

Maybe, I can clarify a bit as I encounter a similar problem. There is no error message, but I see a lot of traffic to pypi.org (This traffic is unwanted)

I masked pypi.org in my hosts file and wanted to force the use of my devpi server, but then, pipenv install fails.

Current constraints:
  ipykernel

I guess, it is closely related to the following issue on github: https://github.com/pypa/pipenv/issues/1783

EDIT: It seems like running pipenv install --skip-lock solves the issue when running against devpi (or something similar) without having access to pypi.org. This was at least the solution for me (with pipenv 11.10.0 and python 3.6.4)
