Error in anyjson setup command: use_2to3 is invalid

Question

#25 3.990   × python setup.py egg_info did not run successfully.
#25 3.990   │ exit code: 1
#25 3.990   ╰─> [1 lines of output]
#25 3.990       error in anyjson setup command: use_2to3 is invalid.
#25 3.990       [end of output]

This is a common error which the most common solution to is to downgrade setuptools to below version 58. This was not working for me. I tried installing python3-anyjson but this didn't work either. I'm at a complete loss.. any advice or help is much appreciated.

If it matters: this application is legacy spaghetti and I am trying to polish it up for a migration. There's no documentation of any kind.

Hello, thank you for responding. I have attempted setting setuptools to both version 58.0.0, and to the latest version. Both times to no success. – Elspeth

Does this answer your question? Error while downloading the requirements using pip install (setup command: use_2to3 is invalid.) – Miru

Answer 1

Downgrading setuptools worked for me

pip install "setuptools<58.0.0"

And then

pip install django-celery

why setuptools break change? – Meagher

How does this solve the problem? – Etymology

Answer 2

Installing setuptools 57.5.0 solved the same issue for me.

pip install setuptools~=57.5.0

Answer 3

If keep getting the error after downgrading setuptools, make sure to have installed wheel:

pip install "setuptools<58.0.0" wheel

UPDATE (2023-11-02): anyjson was removed thanks to Brian Peterson and Aaron recommendation.

Cloche

I know it's an old topic but you need an upvote. The "wheel" part was the important bit I was missing. (I needed a really old troposphere version, but on python 3.11( Thanks – Magritte

couldn't install wheel due to the same use_2to3. Catch 22 here... – Fives

I needed to include pip install wheel without anyjson, otherwise the latter blocked the former from finishing – Personalize

Any other answer is just to downgrade setuptools to 58 or below,but it doesn't work for me,until I saw that you added wheel here,but without anyjson，on Python 3.11,Thanks – Institutional

Answer 4

Installing a version of setuptools lower than 58.0.0 solved the issue.

pip install "setuptools<58.0.0" 

It happens because Use_2to3 has been removed from setuptools >=58.0.0 versions

Allethrin

pip install "setuptools<58.0.0" demjson – Meagher

Answer 5

pip install "setuptools<58.0.0" wheel --no-cache-dir

and after that

pip install django-celery

worked on my pc!

This answer does not add anything new to the currently available answers. – Linlithgow

Answer 6

I tried to run the recommended solutions and all failed for one reason or another. I was able to install anyjson like this:

• Download tar.gz: curl -O https://files.pythonhosted.org/packages/c3/4d/d4089e1a3dd25b46bebdb55a992b0797cff657b4477bc32ce28038fdecbc/anyjson-0.3.3.tar.gz
• Verify checksum: echo '37812d863c9ad3e35c0734c42e0bf0320ce8c3bed82cd20ad54cb34d158157ba anyjson-0.3.3.tar.gz' | sha256sum --check
• Extract tar.gz: tar zxvf anyjson-0.3.3.tar.gz
• Run 2to3 on the extracted dir: 2to3 -w anyjson-0.3.3
• Pip install: pip install anyjson-0.3.3/
