Can't install using pip about pymap3d HOT 11 CLOSED

Hi @2ar0n
that's interesting; Ubuntu 16.04 comes with Python 3.5 by default, which is supposed to work with pymap3d.
This post experienced exactly the same error on a different package, and a commenter said it might work fine regardless of the error.
It seems like it could be a rare issue. Another commenter said it was fixed by reinstalling Python (with something like Miniconda.

I installed a fresh Miniconda Python 3.5 environment and Pymap3D installed without any issues.
You might consider trying the 50MB Miniconda download for Python 3, in general it's nice to avoid using system Python in case issues arise.

Hello @scivision,
I've looked a bit more into the problem and you're right that I seems not the be related to the pymap3d package itself, so I will close this issue.
Nonetheless, I've tried installing it on 4 different machines now (all running Python3.5 on Ubuntu 16.04) and was successful on only one of them. What did work for me was installing from source using pip3 install -e . in the clone repository. Hope this can be useful to anybody.

Hmm, this may have been an issue with too-old pip as would be typical with system Python.
Many projects these days require pip >= 10. Older versions of pip that come with Linux may just fail with weird messages like this.

I expected that too, but the same error came using pip 18.1. I'll double check

from pymap3d.

Here's what I got from Ubuntu 16.04, system Python 3.5.2 and pip==8.1.1:

python3 -m pip install --user pymap3d

errors:

Ubuntu 18.04, system Python 3.6.6 and pip==9.0.1

/usr/bin/python3 -m pip install --user pymap3d

is successful

from pymap3d.

So I am not sure what the issue is with Ubuntu 16.04 and system Python. Generally we advocate not using system Python, but rather a user-installed small Python distro like Miniconda, which does work for me with Python 3.5, 3.6, 3.7

from pymap3d.

I'll keep that in mind! Thank you for all the investigation

from pymap3d.

Yes sorry I don't have time right now to dig into it further. It could be that since Ubuntu 16.04 doesn't have the latest 3.5.x version, there could have been some bugfix that even having the latest pip doesn't help. This is a good thing to note for other developers, as this issue barely shows up on a Google search.

Just another datapoint. The pip install appears to work for me if you specify an older version (this is on ubuntu 16.04 with python 2). It appears that anything below the current 1.8.0 will properly install (in both the "OS" version of pip and in virtualenv's).

from pymap3d.

I believe this may be fixed now. I tried with same systems and it works e.g.

pip install pymap3d

As well as git clone and then

pip install -e .

I recently added more testing and configuration to hopefully fix this issue.
