metawrap installation and salmon question

[sincos2211]

Hello,

I am really new to the metaWRAP, I have some issues with installation and some queries,

1. I tried several to install as the guide, I created a new environment and used mamba to install, but it showed the error, how can I fix this error?:
   mamba install -c ursky metawrap-mg

or

mamba install -c ursky metawrap-mg=1.3.2-0

Looking for: ['metawrap-mg=1.3.2-0']

2. In the quant_bin, there is option -a ( ASSEMBLY/final_assembly.fasta). If I do not include this option, how is it different?
3. If I use salmon separately to find the abundances of genomes (bins), what option in the salmon tool can replace or be similar for -a option in metalwrap? In the salmon, the input is normally indexed first and then quantify, how would be different with the results can be generated using metawrap (metawrap quant_bins -b BIN_REFINEMENT/metawrap_50_10_bins -o QUANT_BINS -a ASSEMBLY/final_assembly.fasta CLEAN_READS/ERR*fastq)

I am new to this so this question might be stupid. Thank you!

You may find your issue with the SOLVER is fixed by adding "--no-channel-priority" to the create command, however, I'm seeing other people with issues like: #528 so it is possible something has broken elsewhere in the install...

mamba create -y --name metawrap --channel ursky metawrap-mg=1.3.2 --no-channel-priority
