mirdeep2 installation error

Question

[szabo.marton]

Hi! I've tried to use mirdeep2 package to miRseq analysis on Ubuntu. However I have no previous experience with seq analysis nor using Ubuntu surface. I followed to instruction provided by the developers, but when I wanted to use the mapper.pl module the following error message came up:

dirname: missing operand
Try ‘dirname --help’ for more information.
Please run the install.pl script first before using the miRDeep2 package
The install script is located in  so just do

cd 
perl install.pl

than I've tried many times to run the install.pl and I've got this:

Building of /home/biochem-ubu/mirdeep2/essentials/bowtie-1.1.1/bowtie successful
Compress::Zlib                   already installed, nothing to do ...
Font::TTf                                        already installed, nothing to do ...
PDF::API2                                        already installed, nothing to do ...

randfold was/is not installed properly

RNAfold was/is not installed properly

Please run the install.pl script again to check if
    everything is properly installed.

I saw there is a question with the similar problem, also I tried many alternative ways to fix it, but none of those worked. Any help would be appreciate!

Have you tried installation using (bio)conda?

Thanks your advice, I'm not familiar with conda, but I guess it's worth a try.
