执行python cgi脚本时出现“504网关超时”

Question

The following example code:

#!/usr/bin/python3
from astropy.time import Time
from astropy.coordinates import solar_system_ephemeris, EarthLocation, get_body

print('Content-Type:text/html;charset=utf-8\n')

t = Time("2014-09-22 23:22")
loc = EarthLocation.of_site('greenwich') 
with solar_system_ephemeris.set('builtin'):
    jup = get_body('jupiter', t, loc) 
print('<h2>',jup.ra.deg,'</h2>')  

works OK when the script runs locally (=136.9111620895066). But if I try to execute it from the server a "504 Gateway Time-out" Nginx error appears.

Maybe something is wrong with the file where astropy holds the ephemerides data? Other astropy, matplotlib, etc. scripts work fine from the server. The error appears every time the script needs ephemerides flles (jpl, esa ...).

确保您拥有 astropy 的最新错误修复版本（v3.2.3， http ://docs.astropy.org/en/latest/changelog.html#id153），因为它修复了 IERS URL 的问题，这可能是导致您出现“504 网关超时”错误。
