nodeenv is failing under conda

[clnorris]

Hello,

I've been using nodeenv to install node into a conda env for the last year or so. I use pip for the installation:

(AppServerEnv) clnorris@nottelling:/mnt/c/Users/clnorris/source/repos/nodeenv$ pip install nodeenv
Collecting nodeenv
  Using cached nodeenv-1.4.0-py2.py3-none-any.whl (21 kB)
Installing collected packages: nodeenv
Successfully installed nodeenv-1.4.0

Installation of a prebuilt node used to work great, but now it is failing as follows:

(AppServerEnv) clnorris@nottelling:/mnt/c/Users/clnorris/source/repos/nodeenv$ nodeenv --node=8.9.4 -p
 * Install prebuilt node (8.9.4) .

As a workaround, I am installing nodeenv from source. Then I can use the --ignore_ssl_certs option to get a successful installation of a prebuilt node.

(AppServerEnv) clnorris@nottelling:/mnt/c/Users/clnorris/source/repos/nodeenv$ pip uninstall nodeenv

Is anyone else using nodeenv from conda, and are you experiencing the issue? Any suggestions on a fix? Don't really like the unsafe workaround.

For reference, here are my currently installed conda packages:

Hi @clnorris

Thanks for the report.

Just tested with virtualenv & python3 & ubuntu 18.04 - could not reproduce the issue:

I am getting the same errors in vanilla Python with nodeenv-1.5.0

[sydneypemberton1986]

I'm getting the same errors in Python 3.8 on macOs Mojave.

Hey @zachzachzach @sydneypemberton1986 !

Thanks for reports!

Could you provide some additional info? Installation steps? Exact version of python, os, conda, etc.
Thanks!

Same error here. Fresh environment with virtualenv, and fresh nodeenv install.

Versions:
MacOx Big Sur 11.4,
Python 3.9,
virtualenv 20.2.2,
nodeenv 1.6.0,
node 16.3.0.

Same with node 14.17.0

[darcyalcantara]

That worked for me:

Source: https://stackoverflow.com/questions/27835619/urllib-and-ssl-certificate-verify-failed-error

[ekalinin]

This is a macOS/Python certificate store problem rather than a nodeenv one - a Python installed from python.org does not use the system keychain until you run Install Certificates.command, which is exactly what fixed it for @darcyalcantara above.

Options today: run that script, or use --ignore_ssl_certs (unsafe). Bundling certifi is proposed in PR #388.

Closing in favour of #388.
