The actual issue here is in check_and_install.py

Traceback (most recent call last):
File "check_and_install_getgauge.py", line 49, in <module>
assert_versions()
File "check_and_install_getgauge.py", line 30, in assert_versions
python_plugin_version = get_version()
File "check_and_install_getgauge.py", line 9, in get_version
data = json.loads(str(out.decode()))
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
return _default_decoder.decode(s)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 384, in raw_decode
raise ValueError("No JSON object could be decoded")

Since it fails and does not install the pip package, the start.py could not get the logger module.

The start.sh script does not handle the error, and even tough check_and_install.py fails it tries to execute start.py, which it should not.

These are the fixes which need to be done

• Set error trap in starter scripts
• Fix the JSON decoding issue.
