<p>在网上找了很久，都说是Python和yum版本不匹配，我现在的环境，Python有两个版本，v2.6.6，v2.7.8，当前Python运行环境的版本是2.7.8，yum的版本是</p>
<pre><code>rpm -qa | grep yum

<pre><code>#!/usr/bin/python
->
#!/usr/bin/python2.6
</code></pre><p>运行yum还是不行，报同样的问题。</p>
<h4 id="推测问题"><a href="#推测问题" class="headerlink" title="推测问题"></a>推测问题</h4><p>推测估计是升级Python2.7.8的时候，原来Python2.6下的包被删了，导致无法运行。重新强制安装一遍所需要的rpm包</p>

<p>在代码库里和命令行下分别查看sapi名称：</p>
<pre><code class="php">echo php_sapi_name(); //cgi-sapi
</code></pre>
<pre><code class="bash">php -r "echo php_sapi_name();" //sli-sapi
</code></pre>
<p>这就清楚了，应用在Web服务器中的就叫做CGI SAPI，应用在终端上的SAPI就叫做CLI SAPI。在windows下安装php你会看到两个exe：php.exe和php-cgi.exe这个就对应的是这两种SAPI。</p>
<p>终端查看PHP版本时，也会输出相关信息 <strong><em>5.6.12 (cli)</em></strong></p>

PHP 5.5.3 (cli)

<p>明明早就升级到5.6了。卸载了5.6，又安装了7.0，还是显示5.5。最后觉得应该是PATH，重新export了一遍PATH,source ~/.bash_profile，再尝试就ok了。</p>
<p>接下来以为一切ok，可以试用7.0了，结果<a href="http://127.0.0.1/居然是显示(PHP" target="_blank" rel="external">http://127.0.0.1/居然是显示(PHP</a> Version 5.6.13),homebrew已经卸载了5.6版本，重启了nginx也无济于事。</p>
<p>最后觉得应该是fpm需要重启下，不然不可能卸载了还在运行。</p>
<pre><code class="bash"># 先关闭之前的php-fpm
sudo killall php-fpm
# 启动PHP-fpm，但需要退出
/usr/local/Cellar/php70/7.0.1/sbin/php-fpm --fpm-config /usr/local/etc/php/7.0/php-fpm.conf
# 启动PHP-fpm
/usr/local/Cellar/php70/7.0.1/sbin/php70-fpm start

<p>重新访问下localhost，版本对了。</p>
