रेल ऐप बनाने के दौरान त्रुटि प्राप्त करना -> रूबी / 2.3.0 / erb.rb: 864: `eval 'में: (erb): 4: वाक्यविन्यास त्रुटि, अप्रत्याशित' = '(सिंटेक्स त्रुटि) - रूबी-ऑन-रेल -4, OSX-elcapitan

मैं रेल पर रूबी के लिए नौसिखिया हूँ। मैं बिना किसी तनाव के इंस्टॉलेशन को पूरा करता हूं, लेकिन "रेल नई" का उपयोग करके एक नया ऐप बनाते समय मुझे त्रुटि मिल रही है और / bin उत्पन्न नहीं हो रहा है। नीचे लॉग इन त्रुटि। मैंने पूरे रात को कारण समझने की कोशिश की है लेकिन हां सफलता के साथ। किसी भी तरह की सहायता को आभार समझेंगे।

मेरी मशीन के कुछ विवरण: मैं ओएस एक्स एल कैप बनाम 10.11.5 का उपयोग कर रहा हूँ

4.2.6 पर रेल 2.3.1 पर रुबी

डेटाबेस मोंगोब उद्यम 3.2.7 है
