使用MEME-chip进行motif分析时报错，使用代码如下：
meme-chip -db HOCOMOCOv11_full_HUMAN_mono_meme_format.meme -meme-p 4 -dna CTCF_ChIP_motif.fasta
报错显示，没有安装 XML::Simple 模块。
安装XML::Simple 和XML::Parser模块后。
cpan[1]> install XML::Simple
Reading '/home/wuhangrui/.cpan/Metadata'
Database was generated on Thu, 01 Jun 2023 07:17:01 GMT
XML::Simple is up to date (2.25).
cpan[2]> install XML::Parser
XML::Parser is up to date (2.46).
显示成功安装。
但是在MEME文件夹下进行make test，meme-chip依然报错。
报错内容如下：（似乎是找不到XML::Parser::Expat module）

请问可以怎么解决？

使用MEME-chip进行motif分析时报错，提示没有安装XML::Simple模块。
安装XML::Simple和XML::Parser模块后，在MEME文件夹下进行make test，meme-chip依然报错，提示找不到XML::Parser::Expat模块。
下面是解决方法：
cpan[1]> install XML::Simplecpan[2]> install XML::Parsertar zxvf XML-Parser-2.44.tar.gzcd XML-Parser-2.44perl Makefile.PLmakemake testmake install
