Mac安装openssl，找不到环境

Question

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

请参见下面的图片

我尝试在.bash_profile中添加路径

，并尝试使用此one中的一些技巧 但它们都不起作用

如果您使用openssl安装了brew，则可能需要从以下位置设置LDFLAGS和CPPFLAGS：

brew info openssl

  

此公式仅适用于小桶，这意味着它没有符号链接到/ usr / local，   因为苹果已经弃用OpenSSL，而是使用自己的TLS和加密库。

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，则会收到类似以下的警告：

$ 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，以便编译器可以找到这些库：

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

那应该可以让您编译node-v0.6.1：
