Failed in the installation following the document on-line

[lupin0lin]

To whom will concern it,

I tried to install PINT following the on-line document (https://nanograv-pint.readthedocs.io/en/latest/installation.html) on my Mac (OS 10.12.6). And no obvious error message when I try to compile the program with

python setup.py install

But when I tried to run the test, I obtained 4 errors and I cannot ensure whether I have successfully installed the package.

Ran 103 tests in 267.917s FAILED (errors=4)

The major errors are related to load the ephemeris file, for example,

ERROR: test_earth (test_solar_system_body.TestSolarSystemDynamic)

I do not clearly understand the possible origin to cause these errors, can anyone give me a hand to solve them?

I'll add the following erros I got when running the test just now on my new MacBook Pro, running Python 3.6.2. The seem mostly focused on J1713 models...

[luojing1211]

@Hazboun6 Which astropy version are you using?

[lupin0lin]

I use astropy v2.0.8, but is it related to the lack on loading the ephemeris file 'de430.bsp'?

[luojing1211]

@lupin0lin I think you are fine. Have you tried to reinstall it recently?

[Hazboun6]

Hi @luojing1211, yeah I'm using astropy 3. I just saw in your requirements.txt that I should be using the older version... Any chance that is going to change soon?

[luojing1211]

@Hazboun6 We are going to discuss this issue in the telecon today.

[Hazboun6]

@luojing1211 Just an FYI, I had another issue when I tried to install PINT in an environment with python 3.7 it didn't work. It's very new, so I just backed off to 3.6.2 and everything, except the above errors worked fine. I no longer have the error messages, but the setup.py was erroring out. Just so you know that might be on the horizon. Obviously you could just use Travis CI to test any Python 3.7 issues...

[paulray]

We can't support astropy 3 until we drop support for Python 2.7. See issue #372

[lupin0lin]

@lupin0lin I think you are fine. Have you tried to reinstall it recently?

I installed PINT with the root authority and gained the same errors. Here are the final messages that I gained at the final.

FAILED (errors=4) make: *** [test] Error 1

Or should I re-download the files (any updated?) and try to install again?

[abhisrkckl]

This issue seems to no longer be valid. Closing.
