json-parse-error when evaluating Python with lispy

[guibor]

Debugger entered--Lisp error: (json-parse-error "invalid token near '_'" "" 1 1 1)
json-parse-string("__PYTHON_EL_eval("lp.eval_to_json(\"\"\"a = 1 \"\"..." :object-type plist :null-object nil)

and now I get

(args-out-of-range "__PYTHON_EL_eval("lp.eval_to_json(\"\"\"import inf..." 2518 nil)

Ultimately was an issue loading the module. I had to install gnureadline on my mac, and replace "import readline" with "import gnureadline as readline" in lispy-python.py
