ฉันได้เขียนสคริปต์เพื่อทำการดาวน์โหลดรวบรวมและติดตั้ง Python ที่ไม่ใช่แพ็คเกจโดยอัตโนมัติ สคริปต์จะติดตั้งเวอร์ชัน Python /optอย่างปลอดภัยห่างจากตัวจัดการแพ็คเกจและเวอร์ชันของระบบของ Python
มันยังใช้การอ้างอิงได้เช่นกันสำหรับ Ubuntu ส่วนใหญ่ ควรทำงานกับ Ubuntu ทุกรุ่นที่รองรับในปัจจุบัน (10.04, 12.04, 12.10 และ 13.04) และอาจเป็นเวอร์ชั่นอื่น ๆ
ฉันรวมไว้ด้านล่างและโพสต์ไว้ที่ที่เก็บ Github ของฉันซึ่งเป็นที่ตั้งหลัก
ควรคัดลอกและบันทึกสคริปต์ลงในโปรแกรมแก้ไขข้อความเช่นbuild_pythonและทำให้chmod u+x build_pythonสามารถเรียกใช้งานได้( ) จากนั้นสามารถรันด้วยพารามิเตอร์สองตัวโดยที่พารามิเตอร์แรกจะต้องเป็นสาขา Python เสมอและพารามิเตอร์ที่สองต้องเป็น Python เวอร์ชั่น
ดูpython.orgสำหรับรายการสำหรับรุ่นที่คุณต้องการรวบรวม
นี่คือตัวอย่างของการใช้งานสคริปต์:
สำหรับรุ่นที่เสถียรหลังจากตรวจสอบรายชื่อแล้วสามารถเรียกใช้ได้
./build_python '3.3.2' '3.3.2'
สำหรับรีลีสการพัฒนาโดยที่พารามิเตอร์ทั้งสองแตกต่างกันในรายชื่อสามารถเรียกใช้เป็น:
./build_python '3.4.0' '3.4.0a1'
เนื้อความของสคริปต์ทำซ้ำด้านล่าง (ไม่มีการเน้นไวยากรณ์ที่นี่เพื่อดูหน้า Githubของฉัน:
