yum install npm 失败并失败：来自 pgdg10 的 repodata/repomd.xml

我尝试通过 yum install npm 命令安装 npm，但每次都会失败并显示以下日志：

Trying other mirror.


 One of the configured repositories failed (PostgreSQL 10  - x86_64),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the 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=pgdg10 ...

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

            yum-config-manager --disable pgdg10
        or
            subscription-manager repos --disable=pgdg10

     5. Configure the failing repository to be skipped, if it is unavailable.
        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 often a nice
        compromise:

            yum-config-manager --save --setopt=pgdg10.skip_if_unavailable=true

failure: repodata/repomd.xml from pgdg10: [Errno 256] No more mirrors to try.

我已经尝试执行以下步骤，但没有任何效果。我没有使用代理，并且我的 RHEL 版本是 7.6，并且具有有效的订阅。

# yum clean all
# rm -rf /var/cache/yum/*
# yum repolist

我检查了我是否正确地通过命令订阅了：

#subscription-manager release --show
Release 7.6

在 /etc/yum.repos.d/ 目录中有两个存储库 pgdg-12-repo.d 和 pgdg-10-repo.d。我不再使用这些存储库了。并删除这两个存储库，然后执行以下命令。有效。

#yum clean metadata
#yum update
#yum install -y gcc-c++ make
#yum install nodejs
