Python Modules

Introduction to Python Modules

The Python module packages add useful objects to the Python language. Modules utilized by packages throughout BLFS are listed here, along with their dependencies.

[Note]

Note

If you want to run tests, several of the following modules depend on the sqlite3 core python module that has not been built in LFS. It is therefore recommended to rebuild Python after installing the recommended dependency listed in Python-3.11.4.

[Important]

Important

In BLFS, we normally build and install Python 3 modules with pip3. Please take care that the pip3 install commands in the book should be run as root unless it's for a Python virtual environment. Running pip3 install as a non-root user may seem to work fine, but it will cause the installed module to be inaccessible by other users.

pip3 install will not reinstall an already installed module by default. For using the pip3 install command to upgrade a module (for example, from meson-0.61.3 to meson-0.62.0), insert --upgrade into the command line. If it's really necessary to downgrade a module or reinstall the same version for some reason, insert --force-reinstall into the command line.

Asciidoc-10.2.0

Introduction to Asciidoc Module

The Asciidoc package is a text document format for writing notes, documentation, articles, books, ebooks, slideshows, web pages, man pages and blogs. AsciiDoc files can be translated to many formats including HTML, PDF, EPUB, and man page.

This package is known to build and work properly using an LFS 12.0 platform.

Package Information

Asciidoc Dependencies

Optional (runtime)

docbook-xsl-nons-1.79.2, fop-2.9, libxslt-1.1.38, Lynx-2.8.9rel.1, dblatex, and W3m

Installation of Asciidoc

Build the module: 

pip3 wheel -w dist --no-build-isolation --no-deps $PWD

This package does not come with a test suite.

Now, as the root user: 

pip3 install --no-index --find-links dist --no-cache-dir --no-user asciidoc

Command Explanations

-w dist: builds the appropriate "wheel" for this module in the directory dist.

--no-build-isolation: tells pip3 to run the build in the system environment instead of creating a temporary build environment.

--no-deps: prevents pip3 from building wheels for the project's dependencies.

--no-index: ignores the package index (only looking at --find-links URLs instead).

--find-links dist: looks for links to archives such as wheel (.whl) files in the directory dist.

--no-cache-dir: disables the cache to prevent a warning when installing as the root user.

--no-user: Prevent mistakenly running the install command as a non-root user.

--upgrade: Upgrade the package to the newest available version. This option is used with the install command if a version of the package is already installed.

--force-reinstall: Reinstall the package even if it is up-to-date. This option is used with the install command if reinstalling the package or reverting to an earlier version of the package.

--no-deps: Do not install package dependencies. This option may be needed with the --upgrade or --force-reinstall options.

docutils-0.20.1

Introduction to docutils

docutils is a set of Python modules and programs for processing plaintext docs into formats such as HTML, XML, or LaTeX.

This package is known to build and work properly using an LFS 12.0 platform.

Package Information

Editor Notes: https://wiki.linuxfromscratch.org/blfs/wiki/docutils

Installation of docutils

To build the Python 3 applications, run the following command: 

pip3 wheel -w dist --no-build-isolation --no-deps $PWD

To install the Python applications run the following as the root user: 

pip3 install --no-index --find-links dist --no-cache-dir --no-user docutils &&

for f in /usr/bin/rst*.py; do
  ln -svf $(basename $f) /usr/bin/$(basename $f .py)
done

To reduce the time needed for loading Python scripts, pip3 install will compile the scripts with extension .py into byte code and save the result into .pyc files in the directory __pycache__. But this package installs .py scripts into /usr/bin. So the byte code files for them will be installed into /usr/bin/__pycache__, which is not allowed by FHS. Still as the root user, remove this directory: 

rm -rfv /usr/bin/__pycache__

--find-links dist: looks for links to archives such as wheel (.whl) files in the directory dist.

--no-cache-dir: disables the cache to prevent a warning when installing as the root user.

--no-user: Prevent mistakenly running the install command as a non-root user.

--upgrade: Upgrade the package to the newest available version. This option is used with the install command if a version of the package is already installed.

--force-reinstall: Reinstall the package even if it is up-to-date. This option is used with the install command if reinstalling the package or reverting to an earlier version of the package.

--no-deps: Do not install package dependencies. This option may be needed with the --upgrade or --force-reinstall options.

Required

charset-normalizer-3.0.1, idna-3.4, and urllib3-2.0.2

Recommended

make-ca-1.12, with p11-kit-0.25.0 (both needed to use system https: certificates, removing an unnecessary dependency on the Certifi module).

Optional

PySocks (also needed for testing)

Optional (for testing)

pytest-7.4.0, Flask<2, httpbin, MarkupSafe<2.1, pytest-mock, pytest-httpbin, sphinx<5, trustme, and Werkzeug<2

Installation of Requests

First apply a patch so that the same environment variable already used to point to system certificates in Python3 following the installation of make-ca can also be used by this module: 

patch -Np1 -i ../requests-2.31.0-use_system_certs-1.patch

Build the module: 

pip3 wheel -w dist --no-build-isolation --no-deps $PWD

Now, as the root user: 

pip3 install --no-index --find-links dist --no-cache-dir --no-user requests

Assuming pytest-7.4.0 is installed, but the other optional dependencies are not, the installation can be tested with the following commands: 

python3 -m venv --system-site-packages testenv &&
source testenv/bin/activate                    &&
pip3 install --force-reinstall sphinx\<5       &&
pip3 install pytest-mock    \
             werkzeug\<2    \
             flask\<2       \
             pytest-httpbin \
             pysocks        \
             trustme                           &&
pip3 install --force-reinstall Markupsafe\<2.1 &&
python3 /usr/bin/pytest tests
deactivate
[Note]

Note

See make-ca-1.12 for how to set the environment variable, and for how local copies of the Certifi and Requests modules installed in a virtual environment will override the system certificates.

Command Explanations

-w dist: builds the appropriate "wheel" for this module in the directory dist.

--no-build-isolation: tells pip3 to run the build in the system environment instead of creating a temporary build environment.

--no-deps: prevents pip3 from building wheels for the project's dependencies.

--no-index: ignores the package index (only looking at --find-links URLs instead).

--find-links dist: looks for links to archives such as wheel (.whl) files in the directory dist.

--no-cache-dir: disables the cache to prevent a warning when installing as the root user.

--no-user: Prevent mistakenly running the install command as a non-root user.

--upgrade: Upgrade the package to the newest available version. This option is used with the install command if a version of the package is already installed.

--force-reinstall: Reinstall the package even if it is up-to-date. This option is used with the install command if reinstalling the package or reverting to an earlier version of the package.

--no-deps: Do not install package dependencies. This option may be needed with the --upgrade or --force-reinstall options.
