解决方案：

1. brew install openssl


2. 下载并解压最新的 cURL



3. 在cURL源目录中：

1. brew install openssl
2. Download and unpack the latest cURL

3. In the cURL source directory:

LDFLAGS="-L/usr/local/opt/openssl/lib" CPPFLAGS="-I/usr/local/opt/openssl/include" ./configure --prefix=/Applications/MAMP/Library/

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 

说明：

找到解决方案的路径以此网站，它描述了MAMP上的一个不同的SSL错误，并建议用

- prefix = / Applications / MAMP / Library / 覆盖MAMP使用的一个。我试过这个，但它没有工作。后来，有东西让我学习cURL编译选项，我注意到在编译它时指定不同版本的OpenSSL的说明。我决定尝试（答应自己，这是最后的尝试，然后我会放弃）。我安装了一个最新的OpenSSL包与Homebrew，它有用的安装后信息说：

The path to finding the solution started with this site, which describes a different SSL error on MAMP, and suggests recompiling a fresh version of cURL with
--prefix=/Applications/MAMP/Library/ to overwrite the one MAMP uses. I tried this but it didn't work. Later, something possessed me to study the cURL compile options, and I noticed instructions for specifying a different version of OpenSSL when compiling it. I decided to give it a try (promising myself that this was the last attempt and then I would give up). I installed an up to date OpenSSL package with Homebrew, and its helpful post-install info said:

If you build your own software and it requires this formula, you'll need to add to your 
build variables:

LDFLAGS:  -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

我在cURL编译选项中看到的，它为上述指定了正确的语法：

That looked similar to something I saw in the cURL compile options, which specified the correct syntax for the above:

LDFLAGS="-L/usr/local/opt/openssl/lib" CPPFLAGS="-I/usr/local/opt/openssl/include" ./configure

我在 - prefix = / Applications / MAMP / Library / 中添加了后面的 code>和 make install ，重新启动MAMP，并释放叹息。

I added back in the --prefix=/Applications/MAMP/Library/, followed by the usual make and make install, restarted MAMP, and sighed with relief.

我后来发现，我从另一个网站投入的一个cURL选项也是必要的，以避免不同的SSL错误（SSL证书问题：无法获取本地发行人证书）。将 CURLOPT_SSL_VERIFYPEER 设置为false解决了一个对我。

I later discovered that one of the cURL options I had thrown in from another website was also necessary to avoid a different SSL error ("SSL certificate problem: unable to get local issuer certificate"). Setting CURLOPT_SSL_VERIFYPEER to false solved that one for me.
