Could not find a version that satisfies the requirement tf-nightly (from versions: none) when install with pip
Python 3.8 is no longer supported which is why there are no matching versions available. Please use Python 3.9, 3.10 or 3.11. Thanks @elfringham , like he said 3.8 is not supported.
You are likely only getting this error now because the last 90 nightlies are stored on pypi which means the last build that supported 3.8 was likely removed.  @PurvangL This issue generally occurs when the version mismatch happens. Python 3.8 is not actively supported so please use 3.9 or later. Please have a look at this reference https://www.tensorflow.org/install/source

 I got the same problem with python3.9, why?
Please go to Stack Overflow for help and support:

https://stackoverflow.com/questions/tagged/tensorflow

If you open a GitHub issue, here is our policy:

1.  It must be a bug, a feature request, or a significant problem with the
    documentation (for small docs fixes please send a PR instead).
2.  The form below must be filled out.
3.  It shouldn't be a TensorBoard issue. Those go
    [here](https://github.com/tensorflow/tensorboard/issues).

**Here's why we have that policy**: TensorFlow developers respond to issues. We want to focus on work that benefits the whole community, e.g., fixing bugs and adding features. Support only helps individuals. GitHub also notifies thousands of people when issues are filed. We want them to see you communicating an interesting problem, rather than being redirected to Stack Overflow.

But none works

```
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement tf-nightly (from versions: none)
ERROR: No matching distribution found for tf-nightly
WARNING: There was an error checking the latest version of pip.
```

You can collect some of this information using our environment capture script:



https://github.com/tensorflow/tensorflow/tree/master/tools/tf_env_collect.sh

You can obtain the TensorFlow version with:

```bash
python -c "import tensorflow as tf; print(tf.version.GIT_VERSION, tf.version.VERSION)"
```

### Describe the problem
