Then how did you install the module XML::CanonicalizeXML? As that module uses libxml2, maybe there is a mismatch between the version of libxml2 that you have installed and the version that the module requires.

You will have to investigate how you installed the module and its C library prerequisites, and how the test suite of the module runs.

    Is there any way to check the version of libxml2?

[reply]

      You need to use the package manager of your OS to show the version of libxml2 and the development headers.

      $ locate libxml2.so

      should show you all the versions which are installed and where. It's up to you to determine to which, if any, a particular program or other lib links.

    How can i get the libxml2 to my pc

[reply]

      Do what you were told here, then build the perl module. It'd be a good idea to review the responses to the several threads you have about this, and take the actions described.

        When i am doing yum install or apt install i am getting an error like this so i will not able to install it on my pc

        yum install libxml2 libxml2-devel

 One of the configured repositories failed (Unknown),
 and yum doesn't have enough cached data to continue. At this point th
+e only
 safe thing yum can do is fail. There are a few ways to work "fix" thi
+s:

     1. Contact the upstream for the repository and get them to fix th
+e problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a
+ working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and 
+the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=<repoid> ...

     4. Disable the repository permanently, so yum won't use it by def
+ault. Yum
        will then just ignore the repository until you permanently ena
+ble it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>
        or
            subscription-manager repos --disable=<repoid>

     5. Configure the failing repository to be skipped, if it is unava
+ilable.
        Note that yum will try to contact the repo. when it runs most 
+commands,
        so will have to try and fail each time (and thus. yum will be 
+be much
        slower). If it is a very temporary problem though, this is oft
+en a nice
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavai
+lable=true

Cannot find a valid baseurl for repo: base/7Server/x86_64
