InvalidVersionSpecError: Invalid version spec: =2.7

Open b-broski opened this issue 3 years ago • 40 comments

Current Behavior

Good morning, I'm just trying to update some packages and I get the following error:

(base) C:\Users\bd>conda update --all
Solving environment: failed

InvalidVersionSpecError: Invalid version spec: =2.7

I get this error no matter what, conda update 'pkg', conda update conda, conda update --all, conda install nltk, etc. I've seen some people get a variation of the error when trying to update a specific package, but 1) I don't know how to isolate this error to a specific package version, and 2) this happens when I try to update or install anything.

Steps to Reproduce


Expected Behavior

I know it should update packages, but I'm confused about the =2.7 within the error. I thought I only had 2.7 installed, but when I check:

(base) C:\Users\bd>python --version
Python 3.7.1

Same problem. InvalidVersionSpecError: Invalid version spec: =2.7 on install/update conda commands. It was working a month ago. Please look into fixing this soon. Its blocking issue.

I had a same problem and updating conda solved it code:- %%bash conda install --channel defaults conda python=3.6 --yes conda update --channel defaults --all --yes and in the next cell !conda --version

conda update is also throwing the same exception. How did you manage to update conda? What you tried isn't working for me.

anjalichablani avatar Apr 24 '21 05:04 anjalichablani

Same error for me, also

(renviron) C:\Users\donrc>conda update --dry-run -n base conda

I personally solved it by deleting the line conda-forge inside the .condarc config file and by not using conda-forge while installing packages/new envs. Hope it helps someone.

I can't update conda because I am in a cluster, and I can't do that..

desmodus1984 avatar May 02 '21 04:05 desmodus1984

unfortunately some packages are only available in conda-forge...

Removing conda-forge from my container's environment spec fixed the issue. Obviously not a solution for the folks who need condo-forge, though :(

@tallestgracie Have you tried just removing conda-forge from .condarc, and then using it to install new packages. I did not try it so I don't know if it could work

I'm having this problem as well. Working on a cluster, and I need conda-forge packages.

clin045 avatar May 06 '21 15:05 clin045

I had to install a personal version of conda on my cluster home drive. Then I cut all the lines it added to my .bashrc, and pasted them into a separate script i ran inside my slurm scripts to run envs with conda-forge packages. very hackish, but it works.

chrysm avatar May 08 '21 04:05 chrysm

Same problem. Working with conda 4.5.4 on a cluster so I can't update conda or delete conda-forge packages.

Ptero64 avatar May 10 '21 15:05 Ptero64

Was facing the same problem for a conda-forge package with python 3.7. Solved it by moving to a new python 3.8 conda environment (https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh)

gautamborad avatar May 13 '21 11:05 gautamborad

Also facing this on a cluster with conda-forge dependencies. Seems I can't install new packages in any of my conda environments, even ones without conda-forge.

a-frantz avatar May 18 '21 14:05 a-frantz

I was having the same problem (cluster) and the only way to deal with it was using an older version of anaconda (4.3.1)

Updating the config file through terminal fix this solution: Run the following command:

conda config --remove channels conda-forge

Same problem with conda 4.3.30

J-BING avatar May 20 '21 19:05 J-BING

This is super hacky, but it worked for me. The problem has to do with how newer versions of conda have added additional valid spec/dependency formats. I was unable to update my conda version, but have access to my conda's python files. This meant that I was able to do the follwoing:

I updated version.py lines 291-298 from:

version_relation_re = re.compile(r'(==|!=|<=|>=|<|>)(?![=<>!])(\S+)$')
regex_split_re = re.compile(r'(\^\S+?\$)')
regex_split_converter = {
    '|': 'any',
    ',': 'all',
}
opdict = {'==': op.__eq__, '!=': op.__ne__, '<=': op.__le__,
          '>=': op.__ge__, '<': op.__lt__, '>': op.__gt__}

to:

version_relation_re = re.compile(r'(==|!=|<=|>=|<|>|=)(?![=<>!])(\S+)$')
regex_split_re = re.compile(r'(\^\S+?\$)')
regex_split_converter = {
    '|': 'any',
    ',': 'all',
}
opdict = {'==': op.__eq__, '!=': op.__ne__, '<=': op.__le__, '=': lambda x, y: x.startswith(y),
          '>=': op.__ge__, '<': op.__lt__, '>': op.__gt__}

This basically adds a new valid spec format. I cannot gaurantee this is safe, but it worked for me, and appears to be consistent with newer versions of conda. You can find where version.py is by running the install/update with -v.

ersinaksar avatar Jun 19 '21 12:06 ersinaksar

Thanks, it worked for me. I personally recommend this one first cause

%%bash conda install --channel defaults conda python=3.6 --yes conda update --channel defaults --all --yes and in the next cell !conda --version

and that delete are both not work on mine.

Rango-Zhang-Hang avatar Jun 19 '21 18:06 Rango-Zhang-Hang

I have encountered the same error, and resolved by upgrade the conda to the lastest version.
