namshi/jose 5.0.2 在 macosx 上需要 lib-openssl

我查看了其他问题，但找不到解决方案。尝试安装时JWT包我收到标题中提到的错误。

我在 mac os x Sierra 上使用 xampp 版本 7.0.8 和 PHP 5.6。我得到的错误如下。

Problem 1
    - namshi/jose 5.0.2 requires lib-openssl * -> the requested linked library openssl has the wrong version installed or is missing from your system, make sure to have the extension providing it.
    - namshi/jose 5.0.1 requires lib-openssl * -> the requested linked library openssl has the wrong version installed or is missing from your system, make sure to have the extension providing it.
    - namshi/jose 5.0.0 requires lib-openssl * -> the requested linked library openssl has the wrong version installed or is missing from your system, make sure to have the extension providing it.
    - tymon/jwt-auth 0.5.9 requires namshi/jose 5.0.* -> satisfiable by namshi/jose[5.0.0, 5.0.1, 5.0.2].
    - Installation request for tymon/jwt-auth ^0.5.9 -> satisfiable by tymon/jwt-auth[0.5.9].

Thanks.

有人使用我开发的 Jose 库遇到过同样的问题。你可以看到他打开的问题在本页.

问题在于，在 MacOS Sierra 上，Composer 无法正确检测到 OpenSSL 实现，并且库是否需要lib-openssl然后出现此消息。

您可以通过执行以下命令行来验证 OpenSSL 实施：

php -i | grep OpenSSL

如果你看到LibreSSL然后尝试改变它：

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/php
brew install curl --with-libssh2 --with-openssl

现在你的 OpenSSL 实现应该是OpenSSL以及安装namshi/jose应该可以正常工作。
