Macos ld:找不到-lssl的库

我用自制软件安装了crystal

brew安装crystal lang

。我能够编译并运行一个“Hello World！”程序，但是当我尝试编译示例http服务器时（稍加修改），我得到了一个错误

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

$ crystal server.cr                                                                                                                                        ~/sw/crystal/Lied-Today
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Error: execution of command failed with code: 1: `cc -o "/Users/Matt/.cache/crystal/crystal-run-server.tmp" "${@}"  -rdynamic  -lz `command -v pkg-config > /dev/null && pkg-config --libs libssl || printf %s '-lssl -lcrypto'` `command -v pkg-config > /dev/null && pkg-config --libs libcrypto || printf %s '-lcrypto'` -lpcre -lgc -lpthread /usr/local/Cellar/crystal-lang/0.21.1_1/src/ext/libcrystal.a -levent -liconv -ldl -L/usr/lib -L/usr/local/lib`

错误：

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

我尝试了以下方法：

将

export LIBRARY\u PATH=“$LIBRARY\u PATH:/usr/local/lib”

添加到~/.zshrc

及

在运行第二个Xcode select命令之前，我需要让Xcode完成安装。

为openssl库提供pkgconfig路径为我解决了这个问题：

PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig" crystal <command>

PKG_CONFIG_PATH=“/usr/local/opt/openssl/lib/pkgconfig”crystal

添加包配置对我来说很有效，下面是添加包配置的命令，因此您无需每次都指定：

echo'export PATH=“/usr/local/opt/llvm@8/bin:$PATH“'>>~/.bash\u配置文件
source~/.bash_配置文件

我必须添加库路径来修复此问题

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

只需包含Lib

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