想试下yar，按着php的扩展教程装，奶奶的熊。结果行不通。好吧，开始折腾。
1.
wget http://pecl.php.net/get/yar-2.0.4.tgz
2.
tar xvzf yar-2.0.4.tgz
3.
cd yar-2.0.4/
4.
phpize
5.
./configure

顶你个肺,我php -m扩展里明明有curl。这下就郁闷了。
怀疑可能是依赖的其他扩展没装
先装msgpack
pecl install msgpack
然后再装,还是报下面的错：
configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.

checking for nawk... no

ERROR: `/private/tmp/pear/temp/yar/configure --with-php-config=/usr/local/opt/php/bin/php-config --enable-msgpack=yes' failed
逼得我看他的报错。
configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.
看这一句警告，行吧，先更新这个re2c:
brew install re2c
再来装:
pecl install yar
就是下面这一句了：
ERROR: `/private/tmp/pear/temp/yar/configure --with-php-config=/usr/local/opt/php/bin/php-config --enable-msgpack=yes' failed
尼玛那个壁，哥哥火爆脾气都上来了：
管他有没有，下个curl:
wget https://curl.haxx.se/download/curl-7.62.0.tar.gz
tar zxvf curl-7.62.0.tar.gz
./configure
make&&make install
然后去配置里加上扩展;
再运行:
pecl install yar
Build process completed successfully

install ok: channel://pecl.php.net/yar-2.0.4

搞定。
