我处于由另一台Ubuntu 16.04托管的虚拟机Ubuntu 16.04（试图创建一个干净且可移植的环境）。
我从String authTokenHeader = request.getHeader("Authorization");
// parse the token
this way安装了EDirect，如下所示：
E-utilities我运行其中一种工具：
cd ~
/bin/bash
perl -MNet::FTP -e \
'$ftp = new Net::FTP("ftp.ncbi.nlm.nih.gov", Passive => 1);
$ftp->login; $ftp->binary;
$ftp->get("/entrez/entrezdirect/edirect.tar.gz");'
gunzip -c edirect.tar.gz | tar xf -
rm edirect.tar.gz
builtin exit
export PATH=${PATH}:$HOME/edirect >& /dev/null || setenv PATH "${PATH}:$HOME/edirect"
./edirect/setup.sh
我遇到了这个问题：
/home/ldar/edirect/esearch -db nucleotide -query "txid590 [Organism]"
我在网上检查了此代码错误501 Protocol scheme 'https' is not supported (LWP::Protocol::https not installed)
No do_post output returned from 'https://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=nucleotide&term=txid590%20%5BOrganism%5D&retmax=0&usehistory=y&edirect_os=linux&edirect=10.9&tool=edirect&email=ldar@ldar-VirtualBox'
Result of do_post http request is
$VAR1 = bless( {
'_msg' => 'Protocol scheme \'https\' is not supported (LWP::Protocol::https not installed)',
'_request' => bless( {
'_uri' => bless( do{\(my $o = 'https://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi')}, 'URI::https' ),
'_content' => 'db=nucleotide&term=txid590%20%5BOrganism%5D&retmax=0&usehistory=y&edirect_os=linux&edirect=10.9&tool=edirect&email=ldar@ldar-VirtualBox',

WebEnv value not found in search output - WebEnv1
。所以我做到了：
LWP::Protocol::https not installed我也尝试使用cpanm install LWP::Protocol::https
cpan -l | grep "LWP::Protocol::https"
Loading internal null logger. Install Log::Log4perl for logging messages
LWP::Protocol::https 6.07
perl --version
This is perl 5, version 26, subversion 2 (v5.26.2) built for x86_64-linux-thread-multi
进行安装，但是同样的问题...
如果我在VM外部（因此，在主机下）运行安装，则不会出现此问题。谢谢
