无法在Magento 2.2.4安装程序上运行composer安装

Question

克隆存储库后，我目前无法在本地主机上设置现有的Magento站点，因此无法运行composer install。 我收到以下错误：

Problem 1
- Installation request for magento/framework 101.0.4 -> satisfiable by magento/framework[101.0.4].
- magento/framework 101.0.4 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.
Problem 2
- Installation request for magento/magento2-base 2.2.4 -> satisfiable by magento/magento2-base[2.2.4].
- magento/magento2-base 2.2.4 requires ext-intl * -> the requested PHP extension intl is missing from your system.
Problem 3
- Installation request for magento/product-community-edition 2.2.4 -> satisfiable by magento/product-community-edition[2.2.4].
- magento/product-community-edition 2.2.4 requires ext-intl * -> the requested PHP extension intl is missing from your system.

因此，似乎缺少一些PHP扩展，但是当尝试通过brew安装它们时，会发生以下错误：

Error: No available formula with the name "php71-mcrypt" 
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching for similarly named formulae...
==> Searching local taps...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.

另外，如果我使用brew list，它会显示mcrypt已经安装，但是卸载并没有帮助。 我也尝试过完全重新安装brew，但这也无济于事。 我对Magento和Brew都缺乏经验，所以如果我在这里缺少任何信息，请告诉我。

Answer 1

您在brew上使用哪个PHP版本？ （php -v）我有类似的时间，即使brew服务显示7.1正在运行，我实际上默认为7.0。

Answer 2

按照显示的顺序输入以下命令：

brew update && brew upgrade
brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/homebrew-php
brew unlink php70 or 56 
brew install php71
curl -s http://php-osx.liip.ch/install.sh | bash -s 7.0

您可以在上面的命令中用7.1替换7.0，以获取7.1版的PHP

如果php -v的输出仍未回显版本7，只需键入此命令以更新您的路径，就可以做到，如php-osx.liip.ch网站上php-osx.liip.ch 。

export PATH=/usr/local/php5/bin:$PATH

要么

export PATH=”$(brew — prefix homebrew/php/php70)/bin:$PATH

要么

export PATH="$(brew --prefix homebrew/php/php70)/bin:$PATH
