英文:
Unable to install perl module in docker file
问题
I am trying to build a lambda layer with Perl support using this prebuilt docker image: https://metacpan.org/pod/AWS::Lambda#Use-Pre-built-Docker-Images
Now I am trying to add this library libtext-roman-perl into the docker image with:
FROM shogo82148/p5-aws-lambda:base-5.36.al2
RUN yum install -y libtext-roman-perl
COPY handler.pl /var/task/
CMD [ "handler.handle" ]
but it is showing No package libtext-roman-perl available. Is this because there is no repository containing this library in the environment?
I've tried yum update but it does not resolve this

yum install 是 Fedora/RedHat/CentOS 安装软件包的方式。这些项目使用 perl-Foo-Bar 命名约定来打包 Perl 模块。因此，你可以尝试：
RUN yum install -y perl-Text-Roman
libfoo-bar-perl 是 Debian/Ubuntu 的命名约定。如果你使用这些发行版（但看起来你不是），那么你应该使用 apt 而不是 yum 来安装它。
RUN apt install libtext-roman-perl
英文:
yum install is Fedora/RedHat/CentOS's way to install packages. These projects use the naming convention perl-Foo-Bar for packaging Perl modules. So you could try:
RUN yum install -y perl-Text-Roman
libfoo-bar-perl is the naming convention of Debian/Ubuntu. If you're using one of those distributions (but you don't seem to be), then you'd use apt to install it instead of yum.
RUN apt install libtext-roman-perl
