错误：需要失败的依赖项 /usr/bin/perl

Question

I am installing Mysql server on Fedora.

When running this command:

[sugumar@localhost softwares]$ rpm -i MySQL-server-5.6.21-1.el6.i686.rpm 

it shows the following error

error: Failed dependencies:
    /usr/bin/perl is needed by MySQL-server-5.6.21-1.el6.i686

So I have installed Perl:

Downloaded Activeperl tarball:

1. tar -xzvf Activeper.tar.gz
2. cd Activeperl

3. sh install.sh

    Enter top level directory for install [/opt/Activeperl]: yes

But still when I try to install Mysql, it shows the same error

error: Failed dependencies:
    /usr/bin/perl is needed by MySQL-server-5.6.21-1.el6.i686

What should I do?

Answer 1

Run Following command

rpm -ivh --nodeps MySQL-server-5.6.21-1.el6.i686.rpm

Try install with no dependencies(nodeps), mostly you wont receive this dependency errors

Answer 2

rpm only knows that software is installed if it is noted in the rpm database. That only happens if you use rpm (or yum or, probably, packagekit) to install the software. Just installing ActivePerl like that isn't going to change anything.

As you seem to have the MySQL rpm downloaded already, you can use yum's "localinstall" feature to install a local rpm and all of its dependencies.

$ yum localinstall MySQL-server-5.6.21-1.el6.i686.rpm

But, like others, I'm really surprised that your system doesn't already have Perl installed. I'd be very wary of a system in that condition.

Answer 3

Perhaps your perl is installed at /bin, not /usr/bin? Try to make a symbolic link for it. In fact, many applications/scripts have their default perl path, either /usr/bin/perl or /bin/perl. So, in my machine, I always have both paths pointing to perl (one physical, one symbolic).

check if you perl is in /bin or /usr/bin

ls -l /bin/perl
ls -l /usr/bin/perl

If that's the problem, try to make a symbolic link:

ln -s /bin/perl /usr/bin/perl

Answer 4

Install the Perl supplied with Fedora:

sudo yum install perl

This should give you /usr/bin/perl (and a lot more).

But how could it go missing in the first place? Looks like someone's been messing with your system.
