pipenv --update fails with SemVer violation

[GPHemsley]

Running pipenv --update (with pipenv 9.0.0) fails with an error like the following:

ValueError: 11.10.1.dev5 is not valid SemVer string

This is presumably due to the release of dev versions of v11.10.1 over the last few days. Multiple runs of the command will fail on different dev versions. (I believe the problem is that, according to SemVer spec item 9, pre-release data should be separated by a hyphen, not a dot; thus the above version should be 11.10.1-dev.5.)

The core issue is actually that this command sucks, which is why it hasn't existed since the 9.0 release series. Use pip to upgrade.

Also, see https://www.python.org/dev/peps/pep-0440/#developmental-releases

[GPHemsley]

SemVer and PEP 440 are inherently incompatible, so I don't know that you need to blame it on the command. 😄

[techalchemy]

Lol. Well I meant that the command should work irrespective of any semver compatibilities, we shouldn't have been doing a semver check there anyway. So I'm just glad that we axed it

Sorry,I'm still confused.Thanks for any help.

My Error:

~ pipenv --update 
...
 File "/usr/local/Cellar/pipenv/11.8.0/libexec/lib/python3.6/site-packages/pipenv/vendor/semver.py", line 50, in parse
    raise ValueError('%s is not valid SemVer string' % version)
ValueError: 11.10.1.dev1 is not valid SemVer string

My understanding:

• https://www.python.org/dev/peps/pep-0440/#developmental-releases

  • X.Y.devN is the valid SemVer string
  • 11.10.1.dev1 is false

• it hasn't existed since the 9.0 release series. Use pip to upgrade.

  • I don't know how to upgrade pipenv by pip
  • I use brew upgrade pyenv

    ➜  ~ pipenv --version
    pipenv, version 11.8.0
    

  • but the pipenv --update is still not working.
    • the same error.

• So...

  • May I make any mistake?

This command doesn’t work. We deleted it from pipenv. Please upgrade using pip, the same way you installed pipenv in the first place
