I'm trying to install the pretermgrowth python package from PyPI with reticulate::conda_install() (running on Windows 10) and I'm getting the following error message:

library(reticulate)
conda_create("project-env")
conda_install("project-env", "pretermgrowth")

PackageNotFoundError: Packages missing in current channels:

  - pretermgrowth

We have searched for the packages in the following channels:

I have the same problem when I also try to install without conda environments reticulate::py_install("pretermgrowth"). For reference, I can pip install the package just fine.

That led me to trying to install using pip = TRUE, which gave me this error

conda_install("neo-extrauterine-growth", "pretermgrowth", pip = TRUE)

Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping
Error: Error installing package(s): "pretermgrowth"

I tried to follow the advice from this answer about putting specific Anaconda directories in my path, but no luck there either.

How can I install this package using reticulate? Is something about the package broken?

  • Is there a pretermgrowth Conda package? – AMC May 09 '20 at 02:35
  • Yup, it's linked in the question up top – Paul Wildenhain May 10 '20 at 04:02
  • Unless I'm looking at the wrong thing, all I see is a link to the pypi page. – AMC May 10 '20 at 19:55
  • Oh I just noticed you asked if it was a __conda__ package. That was one of my main questions -- is it possible to configure `reticulate` to install from PyPI? Or does it need to be a conda package for Windows? – Paul Wildenhain May 11 '20 at 16:20
  • _That was one of my main questions -- is it possible to configure reticulate to install from PyPI?_ I'm not 100% sure, my best guess is no since it's an R package, right? – AMC May 11 '20 at 22:23
  • Correct, it's just on PyPI – Paul Wildenhain May 12 '20 at 03:05
  • _Correct, it's just on PyPI_ Was that in response to my earlier comment (_Unless I'm looking at the wrong thing, all I see is a link to the pypi page._) ? – AMC May 28 '20 at 23:48
  • Haha thanks for sticking in there with me! that was in response to your earlier comment. In response to whether or not its an R package, `pretermgrowth` is a python package, that is on pypi, that I would like to use in R. On a separate note, I think my problem is actually an SSL issue. Though I have no problems `pip install`ing things, when I use `pip = TRUE` in `py_install()` I get a `SSLError("Can't connect to HTTPS URL because the SSL module is not available.")`. – Paul Wildenhain May 29 '20 at 12:17
  • From searching that error message, I found [this](https://stackoverflow.com/questions/54558389/how-to-solve-this-error-while-installing-python-packages-in-rstudio), which seems related. – AMC Jun 03 '20 at 02:11
