Bigchaindb: Syntax error on bigchaindb call in console

[darkodraskovic]

• BigchainDB version: can't get the version since the command bigchaindb fails w/o parameters, but should be latest at the time of this writing, i.e. v. 1.2.0
• Operating System: Ubuntu 17.10
• Deployment Type: [Host]
• BigchainDB driver: [yes]
  
  
  
  • If using a driver please specify, driver type [python]
    
    and version.
  
  

Description

The error started to happen "out of blue". One day bigchain was working normally, the next day it won't start anymore. I've stopped mongodb service and restarted it again with -replSet=bigchain-rs and tried again with the same error.

What I Did

When I issue bigchaindb in linux terminal w/o arguments, I get the following syntax error:

Traceback (most recent call last):
  File "/usr/local/bin/bigchaindb", line 11, in <module>
    load_entry_point('BigchainDB==1.1.0', 'console_scripts', 'bigchaindb')()

Hmm, that's very strange. I'm actually running Ubuntu 17.10 myself these days, so I tried to reproduce your problem just now.

$ cd
$ mkdir temp_bigchaindb
$ cd temp_bigchaindb/
$ which python3
/usr/bin/python3
$ virtualenv -p /usr/bin/python3 bc
$ . bc/bin/activate
(bc) $ pip install bigchaindb
...
(bc) $ bigchaindb -v
bigchaindb 1.2.0

Anyway, it all seemed to work fine.

I noticed that the problem for you happened with File "/usr/local/lib/python3.6/dist-packages/uuid.py", line 138

Maybe you could try updating the uuid package (using pip or whatever)?

[darkodraskovic]

Thanks for the reply. I've done pip uninstall uuid (just in case) and pip3 uninstall uuid and it did work. I think that it has something to do with the fact that uuid is now a built-in python package. Anyway, the issue had to do with the uuid modul. I'm closing the issue. Thanks again.

uuid is bundled with python since version 2.5, you should not install it in your virtual environment.

Yup. Uninstalling uuid via pip sorted this for me.
