मैंने नॉन-पैकेज पायथन संस्करणों के डाउनलोडिंग, संकलन और स्थापना को स्वचालित करने के लिए एक स्क्रिप्ट लिखी है। स्क्रिप्ट पायथन संस्करण /optपैकेज प्रबंधक और सिस्टम संस्करणों से दूर सुरक्षित रूप से पायथन संस्करण स्थापित करता है ।
यह निर्भरता के साथ-साथ उबंटू के अधिकांश संस्करणों के लिए भी प्राप्त करता है। यह वर्तमान में समर्थित सभी उबंटू संस्करणों (10.04, 12.04, 12.10 और 13.04) पर काम करना चाहिए, और शायद अन्य संस्करणों पर।
मैं इसे नीचे शामिल करता हूं, और इसे मेरे जीथूब रिपॉजिटरी में भी पोस्ट किया है , जो मास्टर स्थान है।
स्क्रिप्ट को कॉपी किया जाना चाहिए और एक पाठ संपादक में सहेजा जाना चाहिए, उदाहरण के लिए, build_pythonऔर निष्पादन योग्य ( chmod u+x build_python) बनाया गया और फिर दो मापदंडों के साथ चलाया जा सकता है, जहां पहले पैरामीटर हमेशा पायथन शाखा होना चाहिए, और दूसरा पैरामीटर हमेशा होना चाहिए पायथन संस्करण।
जिस संकलन को आप संकलित करना चाहते हैं, उसके लिए लिस्टिंग के लिए python.org देखें ।
यहाँ स्क्रिप्ट के उपयोग के कुछ उदाहरण दिए गए हैं:
स्थिर रिलीज़ के लिए, सूचियों की जाँच करने के बाद, इसे निम्नानुसार चलाया जा सकता है
./build_python '3.3.2' '3.3.2'
विकास रिलीज के लिए, जहां दो पैरामीटर लिस्टिंग में अलग हैं, इसे निम्नानुसार चलाया जा सकता है:
./build_python '3.4.0' '3.4.0a1'
स्क्रिप्ट के शरीर से नीचे (कोई वाक्य रचना यहाँ पर प्रकाश डाला गयी है कि के लिए, मेरे देखते हैं। Github पेज :
