各位大佬，我想请教一下关于snakemake1的问题：由于软件之间的冲突，因此在snakemake中使用了conda这一指令，但报出Could not create conda environment from/public/home/guoting/lsn/chipship/snakemake_test/envs/bam.yaml:这种错误，请各位大佬帮忙解答一下，蟹蟹了。

以下是代码详情：

rule all:
    input:
        expand("/public/home/guoting/lsn/chipship/snakemake_test/05bam/{sample}.named.bam",sample=['Control','H3K36me3'])
rule bowtie2:
    input:
        trim_r1 = "/public/home/guoting/lsn/chipship/snakemake_test/04hshuangyangben/{sample}_1.trim.fastq.gz"
    output:
        bow_r1 = "/public/home/guoting/lsn/chipship/snakemake_test/05bam/{sample}.named.bam"
    threads:20
    params:
        genome_index = "/public/home/guoting/lsn/chipship/PRJNA984292/hg38_index/GRCh38_noalt_as/GRCh38_noalt_as",
        core = 20
    conda:
        "/public/home/guoting/lsn/chipship/snakemake_test/envs/bam.yaml"
    shell:
        "bowtie2 -p {params.core} -x {params.genome_index} -U {input.trim_r1} | samtools sort -@ {threads} -n -o {output.bow_r1}"

bam.yaml详情：

channels:
  - bioconda
dependencies:
  - bowtie2 =2.5.0
  - samtools =1.17
