Installation problem with pip install #44

Closed jypeter closed 9 years ago

jypeter commented 9 years ago

I have finally been able to install windspharm in both UV-CDAT 1.5.1 and 2.1.0, but it took me quite some time to figure out how to do it :-(

I just typed pip install windspharm, the installation seemed to start, then nothing took place until I typed , and then I got some weird SPHEREPACK license/download errors

I eventually started installing pyspharm first, and typed 'yes' to accept the license+download, and then installed windspharm from the tarball sources

And then I discovered that pip install windspharm worked indeed, when installing windspharm into UV-CDAT versions I had on other servers, but the problem was that the message asking me to type yes or no was not displayed! I found out the hard way I had to use the following steps:

So, my suggestions:

ajdawson commented 9 years ago

First off, thanks for the feedback, it is appreciated.

can you change the installation so that pyspharm is installed without having to type yes, or at least make sure that the user can see the prompt asking him/her to type yes

No I can't do this. Pip is detecting (correctly) that pyspharm is a required dependency of windspharm, and installing it automatically as it didn't find it (or didn't find a version >=1.8 which is what windspharm requires), but I have no control over how this happens, you need to file a report to the pyspharm project about this issue I think.

or can you add an appropriate note in the http://ajdawson.github.io/windspharm/#download-installation section to tell the user to type yes+ when the installation seems to be stuck?

Yes, I can do that.

I thought windspharm was distributed with UV-CDAT still, is that not the case any more?

ajdawson commented 9 years ago

wait till spherepack+pyspharm are silently installed, then windspharm is installed

It isn't silent really is it? I just checked and I see the full output pip should produce, including a message that windspharm is installed and that the dependency pyspharm will be downloaded and installed to satisfy the dependency. The final line I see is:

Successfully installed windspharm pyspharm

Do you not see that?

ajdawson commented 9 years ago

Documentation has been updated.

jypeter commented 9 years ago

Thanks @ajdawson for taking care of this and adding the extra installation note! windspharm is very easy to install once you know the yes trick, and otherwise pretty hard to install

In have added some more notes below for possible future reference:

ajdawson commented 9 years ago

OK thanks for the info @jypeter.

there is no obvious prompt asking the user to type yes

This is not a good thing, but as I said it is out of my hands, this all comes from pyspharm. I can't fix this, only document it (you can see this by doing pip install pyspharm first which will have the familiar issue, and then pip install windspharm which will install with no issue at all). Did you open a pyspharm ticket for this?

jypeter commented 9 years ago

Done! I have opened a pyspharm issue at https://code.google.com/p/pyspharm/issues/detail?id=4

I am also facing problems with windspharm installation.

In my UV-CDAT 2.0.0 installation I can't even import windspharm. It throws no module windspharm error. But windspharm module is there inside the site-packages directory. I have another UV-CDAT 1.3.1 installation. Here importing windspharm is working, but there is no windspharm.cdms module.

So I tried to install windspharm inside UV-CDAT 2.0.0 using pip. As this post mentions it just stops without saying anything at line
Running setup.py egg_info for package pyspharm I typed "yes" after waiting sometime and it gives this error.

@rajeevskurup - Perhaps the best thing you can do is to go and download pyspharm 1.0.8 and make sure that is installed first. These issues are all to do with getting pyspharm installed, once you get that right windspharm installation will be simple. Unfortunately I don't develop or maintain pyspharm, it is a totally separate project so I can't really do much about this problem. I'd also recommend you talk to the UVCDAT developers about getting windspharm working in UVCDAT as I believe it is supposed to work properly out of the box. Again, I'm not a UVCDAT developer so I can't offer you much help beyond that.

Ping @doutriaux1.

rajeevskurup commented 9 years ago

Hi, I finally installed windspharm successfully. But had to manually download both spherepack and pyspharm . and put the fortran codes in pyspharm src folder before installing pyspharm. pyspharm setup was not able to download the spherepack automatically. http://www.scd.ucar.edu/softlib/SPHERE.html URL is not the correct one I think. After installing pyspharm windspharm got installed through pip.

Thanks for the help.

@rajeevskurup uvcdat 2.2.0 bianries are not longer a FULL build, windspharm is not part of it. If building from source you can turn it on with -DCDAT_BUILD_MODE=FULL see: https://github.com/UV-CDAT/uvcdat/wiki/Build https://github.com/UV-CDAT/uvcdat/wiki/System-Requirements and https://github.com/UV-CDAT/uvcdat/wiki/Install-from-source-command-line-options

rajeevskurup commented 9 years ago

I was using UV-CDAT 2.0.0 , from pre built binaries for ubuntu 14.04.
