安装过程问题

../vendor/magento/framework/Code/Generator.php on line 103报错

这一报错通常出现在安装或升级Magento 2的时候，这时请尝试为根目录下的var文件夹设置可写权限。以下为通过Mac的XAMPP安装时的完整报错信息：

Fatal error: Uncaught exception 'Magento\Framework\Exception\LocalizedException' with message 'Can't create directory /Applications/XAMPP/xamppfiles/htdocs/magento2/var/generation/Magento/Framework/App/ResourceConnection/.' in /Applications/XAMPP/xamppfiles/htdocs/magento2/vendor/magento/framework/Code/Generator.php:103 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/magento2/vendor/magento/framework/Code/Generator/Autoloader.php(35): Magento\Framework\Code\Generator->generateClass('Magento\Framewo...') #1 [internal function]: Magento\Framework\Code\Generator\Autoloader->load('Magento\Framewo...') #2 [internal function]: spl_autoload_call('Magento\Framewo...') #3 /Applications/XAMPP/xamppfiles/htdocs/magento2/vendor/magento/framework/Code/Reader/ClassReader.php(19): ReflectionClass->__construct('Magento\Framewo...') #4 /Applications/XAMPP/xamppfiles/htdocs/magento2/vendor/magento/framework/ObjectManager/Definition/Runtime.php(44): Magento\Framework\Code\Reader\ClassReader->getConstructor('Magento\Framewo...') #5 /Ap in /Applications/XAMPP/xamppfiles/htdocs/magento2/vendor/magento/framework/Code/Generator.php on line 103

missing PHP extensions intl.

很明显是缺失PHP组件，那么如何安装呢，先执行如下指令

cd ~ && curl -O http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz 
tar -zxvf autoconf-latest.tar.gz 
cd autoconf-2.69 
./configure 
make 
sudo make install

安装过程可能会提示安装XCode或M4相关软件，请确认安装即可。下一步就是安装intl组件

sudo pecl install intl

安装后还需要在php.ini中加入组件的引用

sudo nano /Applications/XAMPP/xamppfiles/etc/php.ini
extension=intl.so //加入并保存

重启XAMPP中的Apache再次执行检查报错应该就会消失了
