pkg_resources.DistributionNotFound: spectra>=0.0.10

[RichardCorbett]

HI folks, I am going to try learning some DSL2 (I'm been using base nextflow and loving it). To follow the instructions in this tutorial I had to convert the config to use singularity instead of docker, the latter of which isn't allowed on our system.

Otherwise, I just added these lines to the nextflow.config file:

  enabled = true
  autoMounts = true
  runOptions = "-B /tmp/"
}

/* 
 * defines execution profiles for different environments  
 */ 

profiles {
  standard {
    process.container = 'rnaseq-nf_latest.sif'
    singularity.enabled = true
  }

Then I try running with: nextflow run main1.nf The processes all work fine until I get to the multiqc process where I get the following error: "pkg_resources.DistributionNotFound: spectra>=0.0.10"

It is possible that the spectra error is related to using singularity on my part, but I thought I'd flag this is case others are trying this out.
