Entrez Direct's problem

Question

[Neil]

Hello. I have a problem with using Entrez Direct. I'm currently reading "Biostar handbook" and carefully followed the instructions written in that book about installing Entrez Direct. But I get a message error:

501 Protocol scheme 'https' is not supported (LWP::Protocol::https not installed)

The book advice entering these commands:

mkdir -p ~/src 

curl ftp://ftp.ncbi.nlm.nih.gov/entrez/entrezdirect/edirect.zip > ~/src/edirect.zip

unzip -o ~/src/edirect.zip -d ~/src 

echo 'export PATH=~/src/edirect:$PATH' >> ~/.bashrc

source ~/.bashrc

As I said I carefully followed the instruction but still have the error message. How can I solve this problem?

You should install the missing perl module on your machine. https://stackoverflow.com/questions/21123620/lwpprotocolhttps-not-installed-how-to-install

Ok, got it. How can I install this perl module on mac? I tried google but nothing found.

Module installation steps can be found on the stackoverflow link. e.g using cpan

I tried sudo cpan install LWP::Protocol::https and sudo cpan install Bundle::LWP but still can't to run Entrez. After first command I have the message:
