安裝Laravel-Excel(maatwebsite/excel)時，一直停在Updating dependencies (including require-dev)

安裝Laravel-Excel(maatwebsite/excel)時，一直停在Updating dependencies (including require-dev)，看不出哪有問題，從Laravel-Excel -- Installation看起來也沒錯，找半天看到Composer install doesn't actually install library，看了裡頭的回應半天，最後結論，等它update結束。

bash: composer require "maatwebsite/excel:~3.1"

有寫跟沒寫一樣，但記錄一下，免得一直以為有錯

參考網址：
Composer install doesn't actually install library

安裝Composer

執行底下指令就可以安裝了

$cd /tmp (先換到tmp目錄)
$curl -sS https://getcomposer.org/installer | php

得到以下訊息

#!/usr/bin/env php
All settings correct for using Composer
Downloading...

Composer successfully installed to: /private/tmp/composer.phar
Use it: php composer.phar

再執行底下指令改成composer，這樣就可以直接執行composer了

$mv composer.phar /usr/local/bin/composer
$composer

回應如下

......以下省略

若要更新到最新版：

$ composer self-update

回應如下

Updating to version a67eaf04c7eee3d10d7c64f3eef47995ec150ffe.
    Downloading: 100%         
Use composer self-update --rollback to return to version 523aef76d0fa29c18bf42264e88fc9b58acf825c

PHPUnit學習筆記－Broken PHP Configuration on Mavericks or later

之前裝好的PHPUnit後一直沒用，這陣子重新用時，卻發現一直出現底下的訊息

Warning: require(/usr/lib/php/pear/PHPUnit/Autoload.php): failed to open stream: No such file or directory in /usr/bin/phpunit on line 43

Fatal error: require(): Failed opening required '/usr/lib/php/pear/PHPUnit/Autoload.php' (include_path='.:') in /usr/bin/phpunit on line 43

想不透原因是什麼，查到了Broken PHP Configuration on OSX Mavericks這篇，試了下底下的command

$sudo pear -V
//也可以用pear config-get php_dir

output底下的訊息

Could not open input file: /usr/lib/php/pear/pearcmd.php

看來PEAR真的消失了，參考自己之前寫的PHPUnit學習筆記－PHPUnit安裝（使用PEAR），重新安裝一次

$sudo cp /private/etc/php.ini.default /private/etc/php.ini
$sudo php /usr/lib/php/install-pear-nozlib.phar 

$sudo pear config-set php_ini /private/etc/php.ini
$sudo pear channel-update pear.php.net
$sudo pecl channel-update pecl.php.net
$sudo pecl config-set php_ini /private/etc/php.ini
$sudo pear upgrade-all
$sudo vim /private/etc/php.ini

再執行pear -V，發現PEAR ok了，但是執行底下的command，依然同樣的error

$phpunit -v

重新安裝PHPUnit

$sudo pear config-set auto_discover 1
//sudo pear channel-discover
$sudo pear channel-discover pear.phpunit.de
$sudo pear channel-discover components.ez.no
$sudo pear channel-discover pear.symfony-project.com 
$sudo pear channel-discover pear.symfony.com 
$sudo pear install --alldeps phpunit/PHPUnit

再次執行

$phpunit -v

但這次卻一直出現以下的訊息

You have installed PHPUnit via PEAR. This installation method is no longer
supported and http://pear.phpunit.de/ will be shut down no later than
December, 31 2014.

Please read http://phpunit.de/manual/current/en/installation.html and
learn how to use PHPUnit from a PHAR or install it via Composer.

執行底下command，看看裝了什麼

$pear list -c pear.phpunit.de

Installed packages, channel pear.phpunit.de:
============================================
Package Version State
PHPUnit 4.0.18  stable

看起來很正常，但就是不能用，只好咬牙改用Composer的方式安裝了，找到這篇寫的完整的Installing PHPUnit（官網：Composer、安裝Composer）

先Uninstall

$sudo pear uninstall phpunit/PHPUnit
$cd /tmp (先換到tmp目錄)
$curl -sS https://getcomposer.org/installer | php

得到以下訊息

#!/usr/bin/env php
All settings correct for using Composer
Downloading...

Composer successfully installed to: /private/tmp/composer.phar
Use it: php composer.phar

copy composer.phar去/usr/local/bin

$cp composer.phar /usr/local/bin

$php /usr/local/bin/composer.phar global require "phpunit/phpunit=4.3.*"

安裝完後，到~/.composer/vendor下，要能看到phpunit安裝在這裡

autoload.php composer phpunit  symfony
bin  doctrine sebastian

再來做個link

$cd /usr/bin

$sudo ln -s sudo ln -s /Users/alvin/.composer/vendor/phpunit/phpunit/phpunit phpunit

$phpunit --version

得到底下訊息，可以執行了

PHPUnit 4.3.5 by Sebastian Bergmann.
