অ প্যাকেজ পাইথন সংস্করণগুলি ডাউনলোড, সংকলন এবং ইনস্টল করার সমস্ত স্বয়ংক্রিয় করতে আমি একটি স্ক্রিপ্ট লিখেছি। স্ক্রিপ্টটি পাইথনের /optপ্যাকেজ ম্যানেজার এবং সিস্টেম সংস্করণগুলি থেকে নিরাপদে দূরে পাইথন সংস্করণ ইনস্টল করে ।
এমনকি উবুন্টুর বেশিরভাগ সংস্করণের জন্য নির্ভরতাও এনেছে। এটি বর্তমানে সমর্থিত সমস্ত উবুন্টু সংস্করণ (10.04, 12.04, 12.10, এবং 13.04) এবং সম্ভবত অন্যান্য সংস্করণগুলিতে কাজ করা উচিত।
আমি এটি নীচে অন্তর্ভুক্ত করেছি এবং এটি আমার গিথুব সংগ্রহস্থলে পোস্ট করেছি , যা প্রধান অবস্থান।
স্ক্রিপ্টটি অনুলিপি করে একটি পাঠ্য সম্পাদক হিসাবে সংরক্ষণ করা উচিত, উদাহরণস্বরূপ, build_pythonএবং এক্সিকিউটেবল ( chmod u+x build_python) এবং তারপরে দুটি পরামিতি দিয়ে চালানো যেতে পারে, যেখানে প্রথম প্যারামিটারটি সর্বদা পাইথন শাখা হওয়া উচিত, এবং দ্বিতীয় প্যারামিটারটি সর্বদা হওয়া উচিত পাইথন সংস্করণ।
আপনি যে সংস্করণটি সংকলন করতে চান তার তালিকাগুলির জন্য পাইথন.অর্গ দেখুন ।
স্ক্রিপ্টের ব্যবহারের কয়েকটি উদাহরণ এখানে দেওয়া হয়েছে:
স্থিতিশীল মুক্তির জন্য, তালিকাগুলি পরীক্ষা করে নেওয়ার পরে এটি চালানো যেতে পারে
./build_python '3.3.2' '3.3.2'
বিকাশ প্রকাশের জন্য, যেখানে দুটি পরামিতি তালিকাগুলিতে আলাদা, এটি এটি হিসাবে চালানো যেতে পারে:
./build_python '3.4.0' '3.4.0a1'
