我使用Perl 6创建了一个存根服务，但由于“不支持ALPN”而导致错误。
$ cro stub http ds4 ds4
Stubbing a HTTP Service 'ds4' in 'ds4'...
First, please provide a little more information.
Secure (HTTPS) (yes/no) [no]: yes
Support HTTP/1.1 (yes/no) [yes]:
Support HTTP/2.0 (yes/no) [yes]:
Support Web Sockets (yes/no) [no]: yes
$ cd ds4
$ cro run
▶ Starting ds4 (ds4)
Endpoint HTTPS will be at https://localhost:20000/
♻ Restarting ds4 (ds4)
⚠ ds4 HTTP/2 is requested, but ALPN is not supported

我搜索了这个错误，但我得到的是重建nginx和Apache的信息，我没有使用。它提到了libssl，在这个相当古老的安装中，我有libssl1.0.0:i386和libssl0.9.8:i386没有更新的软件包。
手动编译新的libssl可能会解决我遇到的问题吗？
更新：假设我确实安装了较新的libssl，问题仍然存在：
$ cd $(mktemp -d)
$ wget https://www.openssl.org/source/openssl-1.1.1-pre6.tar.gz
$ tar -xvvf *
$ cd open*
$ ./config && make
$ make
$ sudo make install
...
$ zef uninstall Cro::Core Cro::HTTP cro Cro::TLS Cro::WebSocket OpenSSL IO::Socket::SSL IO::Socket::SSL::Async
$ zef install --/test cro

将新的var HabJax = HabJax || function() {
"use strict";
if(window.location.hash) {
HabJax.handle_ajax();
}
window.addEventListener("hashchange", function(){
HabJax.handle_ajax();
}, false);
return this;
};
window.onload = function(){
this.HabJax = new HabJax();
}
HabJax.prototype = {
page: null,
self: this,
hotelBase: 'http://localhost/Ajax/',
handle_ajax: function()
{
var query_string = window.location.hash;
query_string = query_string.substr(1);
query_string = query_string.substr(1);
if(query_string != 'index' && query_string != '0' && query_string != '' && query_string != null) {
$.ajax({
type: "POST",
url: this.hotelBase + query_string,
success: function(data) {
$("#contentInner").slideUp('fast', function() {
$("#content").html(data);
$("#contentInner").slideDown('slow');
});
HabJax.initialize();
}
});
} else {
window.location.hash = '!1';
}
},
initialize: function()
{
console.log('HabJax: Initialized (Page: ' + this.getPage() + ')');
this.page = this.getPage();
this.executePageFunctionalities(this.page);
window.onhashchange = function() {
HabJax.page = HabJax.getPage();
HabJax.executePageFunctionalities(HabJax.page);
}
return true;

getPage: function()

var page = location.href,

if (page.indexOf('&') != -1)

return (pageName == '' ? '0' : pageName);

executePageFunctionalities: function(page)

switch (page)

case null:

文件安装到系统通常需要更新.so的缓存; apt，rpm和朋友都会在需要时自动在安装后挂钩中执行此操作，但是当您手动安装库时，可能必须手动执行。
执行此操作的命令是
ld
希望有所帮助！
