Calling
import subprocess
print subprocess.Popen(['java', '-version'])
Gives the error
OSError: [Errno 8] Exec format error
But that can be fixed by changing the above to,
print subprocess.Popen(['java', '-version'], executable='/bin/sh')
How can I fix sh.Command the same way?
import sh
print sh.Command('java').bake('-version')()
Because it then gives the exact same error,
OSError: [Errno 8] Exec format error
Try this
if sys.platform == 'darwin':
java = sh.Command('/bin/sh').bake('java')
else:
java = sh.Command('java')
print java.bake('-version')()
@nosklo's answer definitely does do what I asked, and I'll keep it as the correct answer, but that wasn't what my problem was.
Basically, as @nosklo hinted at on irc, this error comes when there's confusion between files, treating a binary like a script, or a script like a binary. So that points definitely to java on the build machine.
which java
/usr/bin/java
ls -la /usr/bin/java
/usr/bin/java -> java.new
cat /usr/bin/java
' java.old -Djava.awt.headless=true "$@" '
ls -la /usr/bin/java.old
/usr/bin/java.old -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
My Java, /usr/bin/java, was a symlink to an executable script, java.new file without a shebang, which forwarded everything to java.old, which was a symlink to the main Java...
Talk about convoluted, but hopefully this might help someone who can't take the easy out the was available to me.
