Directly Stating a GitHub Source in requirements.txt
In software development, managing dependencies is crucial for project stability and reproducibility. pip, a popular package manager for Python, plays a vital role in this process. When a library is installed from a remote GitHub repository, it can be challenging to specify it in the requirements.txt file. This file ensures that the correct versions of dependencies are installed during project setup.
To overcome this challenge, it is important to understand the correct syntax for specifying GitHub sources in requirements.txt. The typical format of a requirements.txt file includes package names and versions, such as:
package-one==1.9.4 package-two==3.7.1 package-three==1.0.1 ...
However, when specifying a GitHub source, the package name and version convention is not required. Instead, the syntax follows the following format:
package-name @ git+git://github.com/username/reponame@specific-specifier
The specific specifier can be a commit hash, branch name, tag, or release, depending on your requirements. Here are some examples:
-
Commit hash (41b95ec):
package-two @ git+https://github.com/owner/repo@41b95ec
-
Branch name (main):
package-two @ git+https://github.com/owner/repo@main
-
Tag (0.1):
package-two @ git+https://github.com/owner/[email protected]
-
Release (3.7.1):
package-two @ git+https://github.com/owner/repo@releases/tag/v3.7.1
It is important to note that in certain versions of pip, it may be necessary to update the package version in the package's setup.py file. This ensures that pip recognizes the requirement correctly and installs the updated version.
By following these guidelines, developers can specify GitHub sources directly in their requirements.txt files, facilitating dependency management and ensuring the integrity of their software projects.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
