ld:找不到-lssl的库

Question

我用自制软件安装了水晶brew install crystal-lang.我能够编译并运行"Hello World!" 程序,但当我尝试编译示例http服务器(稍作修改)时,我收到一个错误.

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
ld: library not found for -lssl

我尝试过以下方法:

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

和

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

Answer 1

我不得不添加 LIBRARY_PATH 来解决这个问题。

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

Answer 2

在运行第二个xcode-select命令之前,我需要让Xcode完成安装.

Answer 3

只需包含 Lib

brew install openssl
echo 'export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/' >> ~/.zshrc
source ~/.zshrc
