無法在Magento 2.2.4安裝程序上運行composer安裝

Question

克隆存儲庫后，我目前無法在本地主機上設置現有的Magento站點，因此無法運行composer install。 我收到以下錯誤：

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擴展，但是當嘗試通過brew安裝它們時，會發生以下錯誤：

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，它會顯示mcrypt已經安裝，但是卸載並沒有幫助。 我也嘗試過完全重新安裝brew，但這也無濟於事。 我對Magento和Brew都缺乏經驗，所以如果我在這里缺少任何信息，請告訴我。

Answer 1

您在brew上使用哪個PHP版本？ （php -v）我有類似的時間，即使brew服務顯示7.1正在運行，我實際上默認為7.0。

Answer 2

按照顯示的順序輸入以下命令：

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替換7.0，以獲取7.1版的PHP

如果php -v的輸出仍未回顯版本7，只需鍵入此命令以更新您的路徑，就可以做到，如php-osx.liip.ch網站上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
