AttributeError: module 'json' has no attribute 'JSONEncoder' #19691

JoCo356 · 2021-09-25T18:39:57Z

Describe the bug
I can't run "az login" , "az versions" or "az upgrade", it shows up an AttributeError.

Traceback (most recent call last):
  File "/usr/local/Cellar/[email protected]/3.9.7/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 197, in _run_module_as_main

    class _ComplexEncoder(json.JSONEncoder):
AttributeError: module 'json' has no attribute 'JSONEncoder'

To Reproduce
Run "az login" or "az versions" on the terminal.

Expected behavior
I expected that when I runned az login an isolated window could open on the internet logging in.

Environment summary
I am using a macOS Catalina version 10.15.7 and I use .zshrc. I am trying to run "az login" in a pyenv which uses python 3.7.5.

Additional context
When I run "ls -l /System/Library/Frameworks/Python.framework/Versions" it gives me:

total 0
lrwxr-xr-x   1 root  wheel    3 Jul 20  2020 2.3 -> 2.7
lrwxr-xr-x   1 root  wheel    3 Jul 20  2020 2.5 -> 2.7

lrwxr-xr-x   1 root  wheel    3 Jul 20  2020 Current -> 2.7

I already run "brew update && brew install python3 && brew upgrade python3" and "brew link --overwrite python3" and relinked again. And I am aware of this webpage https://docs.microsoft.com/pt-pt/cli/azure/install-azure-cli-macos?view=azure-cli-latest. I also run "brew upgrade" because it asked to do that after running "brew update", I had nghttp2 and openjdk outdated. and "brew reinstall azure-cli". When I run "brew update && brew install python3 && brew upgrade python3" it says:

Already up-to-date.
Warning: [email protected] 3.9.7 is already installed and up-to-date.
To reinstall 3.9.7, run:
  brew reinstall [email protected]
Warning: python3 3.9.7 already installed

And when "brew link --overwrite python3":

Warning: Already linked: /usr/local/Cellar/[email protected]/3.9.7
To relink, run:
  brew unlink [email protected] && brew link [email protected]

Tried the relink but didn't worked.

Also uninstalled with command "brew uninstall azure-cli" and re-installed with "brew update && brew install azure-cli", at my pyenv. Didn't work.

Hope you can help me.

@jiasli for awareness

Azure CLI uses the python installed by brew, instead of the one installed by pyenv.

Could you check the version of /usr/local/Cellar/azure-cli/2.28.0/libexec/bin/python (#19027 (comment)):

# You may need to replace version 2.28.0 with the one you are using in the future
ls -l /usr/local/Cellar/azure-cli/2.28.0/libexec/bin/python
/usr/local/Cellar/azure-cli/2.28.0/libexec/bin/python -V

Also, can JSONEncoder be imported?

/usr/local/Cellar/azure-cli/2.28.0/libexec/bin/python -c "from json import JSONEncoder"

Thanks for helping, @jiasli and @yonzhan.

I don't understand

You may need to replace version 2.28.0 with the one you are using in the future

Should I reinstall python 3.9.7. at /usr/local/Cellar/azure-cli/2.28.0/libexec/bin/python directory ? But it was installed by azure-cli, right? When I did:
brew update && brew install azure-cli

This could be of use: https://docs.brew.sh/Homebrew-and-Python

jiasli · 2021-09-27T02:51:26Z

You may need to replace version 2.28.0 with the one you are using in the future

The current Azure CLI is 2.28.0. I am only saying in the future you may need to replace the version number with 2.29.0, 2.30.0, etc. 😄

`/usr/local/Cellar/azure-cli/2.28.0/libexec/bin/python -c "from json import JSONEncoder"

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name 'JSONEncoder' from 'json' (unknown location)

/usr/local/Cellar/azure-cli/2.28.0/libexec/bin/python points to /usr/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.9/bin/python3.9. As you cannot import JSON, that means the Python installation is broken.

What is the result of

/usr/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.9/bin/python3.9 -c "from json import JSONEncoder"

Could you reinstall Python and see if JSONEncoder can be imported?

Any more ideas? I have no clue. Maybe it's reinstalling on a different directory, but, as you said, user/local/cellar/azure-cli/2.28.0/libexec/bin/python is pointing to user/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.9/bin/python3.9. Again, thanks for the help @jiasli .

JoCo356 · 2021-09-27T15:39:45Z

Okay one information, the python3.9. comes from my operating system.

jiasli · 2021-09-28T02:33:46Z

@JoCo356, apparently the Python installation is broken:

/usr/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.9/bin/python3.9 -c "from json import JSONEncoder"

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name 'JSONEncoder' from 'json' (unknown location)

I am not really sure why it fails. Perhaps you may reach out to Homebrew? https://github.com/Homebrew/discussions/discussions

JoCo356 · 2021-10-05T17:35:12Z

Hello, first I had this:

joco@Jo-MBP ~ % python3
Python 3.9.7 (default, Sep  3 2021, 12:45:31)
[Clang 12.0.0 (clang-1200.0.32.29)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from json import JSONEncoder
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'JSONEncoder' from 'json' (unknown location)
>>> exit()

Then I did >> sudo rm -rf /usr/local/bin/python3
I run brew doctor to find symlinks that needed to delete. (https://apple.stackexchange.com/questions/284824/remove-and-reinstall-python-on-mac-can-i-trust-these-old-references) None was found.
I wanted to reinstall with homebrew:

joco@Jo-MBP ~ % brew install python3
Warning: [email protected] 3.9.7 is already installed and up-to-date.
To reinstall 3.9.7, run:
  brew reinstall [email protected]

Now I have:

joco@Jo-MBP ~ % python3
Python 3.8.2 (default, Dec 21 2020, 15:06:04)
[Clang 12.0.0 (clang-1200.0.32.29)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from json import JSONEncoder
>>> exit()

And

joanacosta@Joanas-MBP ~ % azure login
zsh: command not found: azure

Hope you can help me, I am not an expert on this, but I want to be able to solve my problem. If you still think it is better to reach out homebrew, okay.

jiasli · 2021-10-08T01:05:48Z

The command name of Azure CLI is az, not azure. Does az work now?

JoCo356 · 2021-10-12T08:02:54Z

Yes, now az login works!
