利用dada2生成特征表，输入命令（省略了部分选项）：
qiime dada2 denoise-paired --i-demultiplexed-seqs $workdir/1.import_data/demux.qza --p-n-threads 2 --p-trim-left-f 29 --p-trim-left-r 18
提示：
Plugin error from dada2:
An error was encountered while running DADA2 in R (return code 1), please inspect stdout and stderr to learn more.
Debug info has been saved to /tmp/qiime2-q2cli-err-u8wvbzh9.log
打开日志文件：
Error in library(BiocManager, quietly = TRUE) :
there is no package called ‘BiocManager’
Calls: .First -> library
Execution halted
问题：
是不是缺少BiocManager这个包？是镜像ampliseq-q2中缺乏呢，还是系统本身缺少，该如何解决，谢谢！
