“No such file: 'requirements.txt' error” while installing Quartz module

Question

When I try to install Quartz on my system using pip install Quartz , I face with the following error. I use Mac OSX with Anaconda. Any help is appreciated.

Complete output from command python setup.py egg_info:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/private/var/folders/sb/llj7h5px227_5b0__3v0sw5r0000gn/T/pip-build-qf8ezbu5/Quartz/setup.py", line 35, in <module>
    install_requires=read_dependencies("requirements.txt"),
  File "/private/var/folders/sb/llj7h5px227_5b0__3v0sw5r0000gn/T/pip-build-qf8ezbu5/Quartz/setup.py", line 7, in read_dependencies
    with open(req_file) as req:
FileNotFoundError: [Errno 2] No such file or directory: 'requirements.txt'

Answer 1

There seems to be a bug in the setup.py of the package, so I tried the following:

1. Run: pip download quartz .
2. Find the downloaded quartz-0.0.1.dev0.tar.gz .

3. Extract and in setup.py find the following line

    install_requires=read_dependencies(“requirements.txt") 

   and change it to:

    install_requires=read_dependencies("quartz.egg-info/requires.txt") 

4. Run: pip install -e /path/to/quartz-0.0.1.dev0 .

Setup should be completed w/o errors.

Alternatively try this (which fixes ImportError: No module named 'Quartz' when installing pyautogui I encountered when installing pyautogui ):

1. pip install pyobjc-core
2. pip install pyobjc-framework-Quartz

This is the bug of quartz package which is missing requirements.txt file in MANIFEST.in as per author's comment on GitHub issue , therefore it's not shipped with the sources. This won't be fixed anytime soon as it's currently abandoned due to poor architectural design.

So you can either:

• Manually download sources from GitHub and run the setup.py from there to install quartz package.
• Download package by pip download quartz , and place the missing requirements.txt file from GitHub into extracted sources, and run the install.
• Or follow steps provided in @bam answer .

There is ongoing work on new version and it will be published soon when it is ready.
