Question: I'm attempting to install the PyGObject library in pycharm following this guide https://pygobject.gnome.org/getting_started.html attempting to do step 3 on the Ubuntu / Debian section: pip3 install pycairo  and this is what is returned:  × Preparing metadata (pyproject.toml) did not run successfully. │ exit code: 1 ╰─> [48 lines of output] + meson setup /tmp/pip-install-9mn9tc6a/pycairo_3bd8575d46fa4c3ba97005887d18ca79 /tmp/pip-install-9mn9tc6a/pycairo_3bd8575d46fa4c3ba97005887d18ca79/.mesonpy-n59ji4fk -Dbuildtype=release -Db_ndebug=if-release -Db_vscrt=md -Dwheel=true -Dtests=false --native-file=/tmp/pip-install-9mn9tc6a/pycairo_3bd8575d46fa4c3ba97005887d18ca79/.mesonpy-n59ji4fk/meson-python-native-file.ini The Meson build system Version: 1.5.2 Source dir: /tmp/pip-install-9mn9tc6a/pycairo_3bd8575d46fa4c3ba97005887d18ca79 Build dir: /tmp/pip-install-9mn9tc6a/pycairo_3bd8575d46fa4c3ba97005887d18ca79/.mesonpy-n59ji4fk Build type: native build Project name: pycairo Project version: 1.27.0 C compiler for the host machine: cc (gcc 11.4.0 "cc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0") C linker for the host machine: cc ld.bfd 2.38 Host machine cpu family: x86_64 Host machine cpu: x86_64 Program python3 found: YES (/home/demerf/PycharmProjects/gtkgtk/.venv/bin/python) Compiler for C supports arguments -Wall: YES Compiler for C supports arguments -Warray-bounds: YES Compiler for C supports arguments -Wcast-align: YES Compiler for C supports arguments -Wconversion: YES Compiler for C supports arguments -Wextra: YES Compiler for C supports arguments -Wformat=2: YES Compiler for C supports arguments -Wformat-nonliteral: YES Compiler for C supports arguments -Wformat-security: YES Compiler for C supports arguments -Wimplicit-function-declaration: YES Compiler for C supports arguments -Winit-self: YES Compiler for C supports arguments -Winline: YES Compiler for C supports arguments -Wmissing-format-attribute: YES Compiler for C supports arguments -Wmissing-noreturn: YES Compiler for C supports arguments -Wnested-externs: YES Compiler for C supports arguments -Wold-style-definition: YES Compiler for C supports arguments -Wpacked: YES Compiler for C supports arguments -Wpointer-arith: YES Compiler for C supports arguments -Wreturn-type: YES Compiler for C supports arguments -Wshadow: YES Compiler for C supports arguments -Wsign-compare: YES Compiler for C supports arguments -Wstrict-aliasing: YES Compiler for C supports arguments -Wundef: YES Compiler for C supports arguments -Wunused-but-set-variable: YES Compiler for C supports arguments -Wswitch-default: YES Compiler for C supports arguments -Wno-missing-field-initializers: YES Compiler for C supports arguments -Wno-unused-parameter: YES Compiler for C supports arguments -fno-strict-aliasing: YES Compiler for C supports arguments -fvisibility=hidden: YES Found pkg-config: YES (/usr/bin/pkg-config) 0.29.2 Run-time dependency cairo found: YES 1.16.0 Run-time dependency python found: NO (tried pkgconfig, pkgconfig and sysconfig) ../cairo/meson.build:51:15: ERROR: Python dependency not found A full log can be found at /tmp/pip-install-9mn9tc6a/pycairo_3bd8575d46fa4c3ba97005887d18ca79/.mesonpy-n59ji4fk/meson-logs/meson-log.txt [end of output]  I'm running Ubuntu 22.04.5 LTS and python 3.12 and very unfamiliar with linux systems, the log file at /tmp/pip-install-9mn9tc6a/pycairo_3bd8575d46fa4c3ba97005887d18ca79/.mesonpy-n59ji4fk/meson-logs/meson-log.txt  cannot be found. attempting to do step 4 also returns a similar error.

Answer: Unless you need a new version Ubuntu packages it (as the docs say): sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-4.0  Otherwise don’t skip step 2: sudo apt install libgirepository1.0-dev gcc libcairo2-dev pkg-config python3-dev gir1.2-gtk-4.0
