How to Install Packages Directly from GitHub in requirements.txt

In certain situations, developers may need to install dependencies directly from a specific GitHub repository. While the pip install git git://github.com/example/repo.git command effortlessly installs such libraries, encapsulating this dependency in a requirements.txt can prove troublesome.

Problem:

Attempts to include a -f directive in requirements.txt, such as:

-f git+git://github.com/mozilla/elasticutils.git
elasticutils==0.7.dev

result in an error during pip install -r requirements.txt:

"Could not find a version that satisfies the requirement elasticutils==0.7.dev"

Solution:

Traditionally, requirements.txt specifies dependencies using the package-name==version convention. However, when referencing GitHub repositories, this format is not required:

package-one==1.9.4
package-two @ git+https://github.com/owner/repo@41b95ec
package-three==1.0.1

In the above example, @ denotes a GitHub reference. The following suffixes can be applied to specify various sources:

• @41b95ec: Commit hash
• @main: Branch name
• @0.1: Tag
• @releases/tag/v3.7.1: Release

Note:

In some pip versions, updates to packages installed through the GitHub repository reference may not be detected unless the package's setup.py version is manually incremented.
