Cannot pip install orjson (python 3.6).

[loomcode]

sudo pip3 install --upgrade orjson:

Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/usr/lib/python3.6/tokenize.py", line 452, in open
        buffer = _builtin_open(filename, 'rb')
    FileNotFoundError: [Errno 2] No such file or directory: '/tmp/pip-build-3dwbn4b3/orjson/setup.py'

Not sure why it can't find setup when it was just downloaded. I've verified that it exists in the source.

I've got the same problem.

I've got the same problem.

Version 3.4.0 cannot be installed, version 3.3.0 can be installed.

You probably have an old pip. Try upgrading pip first:

python -m pip install --upgrade pip

I had the same issue with pip version 18, latest version fixes the issue.

I have maybe made this obvious in https://github.com/ijl/orjson#install now.

python -m pip install --upgrade pip

This worked for me.

@ijl

I can install manually via pip, but project requirements (and readme) state python >=3.7 which prevent adding orjson in dependency management tools like Poetry.
Any chance to lower those to 3.6?

Thanks!

nvm i see you just dropped 3.6 support, i'll just pin to previous version.

[drewm1980]

Python 3.6 support was removed, and coincidentally, support for correct round-tripping of float -> json -> float were added in the same release 3.6.2.

Can anyone clarify if there is a known problem with orjson 3.6.2 on python3.6, or is it just a matter of building it myself without support?

[drewm1980]

Put another way, was there a non-trivial technical reason for dropping python 3.6 when you did?

Found it:
commit a116ddf
Author: ijl ijl@mailbox.org
Date: Sun Aug 15 17:33:55 2021 +0000

pyo3 ^0.14.2

python3.6 is dropped because it's nearly end of life and there
is now assertion error in pyo3::gil::prepare_freethreaded_python
in CI when running integration/thread.

[drewm1980]

The version with the float round-tripping that I want was introduced in:
2719fc7

[drewm1980]

So unfortunately for me, there was no commit for python 3.6 with correct round-tripping of floating point numbers.
