node.js - Mac安装openssl，环境找不到

Question

我已经安装了openssl，当我输入openssl时，命令行可以识别它。但是我的 Node 配置找不到它。

看下面的图片

我尝试在 .bash_profile 中添加路径

并尝试此 one 中的一些提示但它们都不起作用

如果您使用 brew 安装了 openssl，您可能需要设置 LDFLAGS 和 CPPFLAGS，来自:

brew info openssl

This formula is keg-only, which means it was not symlinked into /usr/local, because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig

如果您尝试链接，您将收到如下警告:

$ brew link --force openssl
Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
  -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

您可以做的是创建一个符号链接(symbolic link)，以便编译器可以找到这些库:

$ ln -s /usr/local/opt/openssl/include/openssl /usr/local/include

这应该允许您编译node-v0.6.1:
