Mac下安装pear库+phpDocumentor

1. 首先安装pear：

curl -o go-pear.php https://pear.php.net/go-pear.phar

看见这个就安装OK：

% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 3512k 100 3512k 0 0 392k 0 0:00:08 0:00:08 --:--:-- 732k

2. 然后执行：

会发现在当前目录下会有 go-pear.php

sudo php go-pear.php

输入密码后一直确认就行，这样就安装了pear

3.安装phpDocumentor

到pear的安装目录下，直接执行下面这行命令时，我查了一下我的安装目录在 ./pear/bin/

./pear install phpDocumentor

直接报warning，提示

WARNING: "pear/PhpDocumentor" is deprecated in favor of "channel://pear.phpdoc.org/phpdocumentor"
WARNING: configuration download directory "/tmp/pear/install" is not writeable. Change download_dir config variable to a writeable dir to avoid this warning
WARNING: channel "pear.php.net" has updated its protocols, use "pear channel-update pear.php.net" to update
Cannot install, php_dir for channel "pear.php.net" is not writeable by the current user
好像是channel有问题，查了下资料，作出以下调整

执行

sudo pear channel-discover pear.phpdoc.org

提示成功了

Adding Channel "pear.phpdoc.org" succeeded
Discovery of channel "pear.phpdoc.org" succeeded

4. 然后执行安装phpDocument

sudo pear install phpdoc/phpDocumentor

就可以看到下载成功了
