macos - ld : library not found for -lssl

Question

我用自制软件 brew install crystal-lang 安装了 crystal。我能够编译并运行“Hello World!”程序，但是当我尝试编译示例 http 服务器(稍作修改)时，出现错误。

HTTP 服务器:

require "http/server"

port = 3000

server = HTTP::Server.new(port) do |context|
  context.response.content_type = "text/plain"
  context.response.print "Hello world! The time is #{Time.now}"
end

puts "listening on http://localhost:" + port.to_s
puts "listening on http://localhost:#{port}"
server.listen

错误:

$ crystal server.cr                                                                                                                                        ~/sw/crystal/Lied-Today

我试过以下方法:

添加 export LIBRARY_PATH="$LIBRARY_PATH:/usr/local/lib" 到 ~/.zshrc。

和

$ xcode-select --install
$ xcode-select --switch /Library/Developer/CommandLineTools

我必须添加 LIBRARY_PATH 来解决这个问题。

export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
