致命錯誤：未捕獲錯誤：在phar中調用未定義的函數Symfony \\ Polyfill \\ Mbstring \\ iconv（）：

Question

我使用Ubuntu 16.04 LTS

PHP 7.0.13 NetBean

我嘗試在NetBeans環境中運行與作曲家鏈接的一些操作，我有這些日志

"/usr/local/ampps/php-7.0/bin/php" "/home/arfa/www/composer.phar" "--ansi" "--no-interaction" "self-update"


Fatal error: Uncaught Error: Call to undefined function Symfony\Polyfill\Mbstring\iconv() in phar:///home/arfa/www/composer.phar/vendor/symfony/polyfill-mbstring/Mbstring.php:520

Done.

該問題與我的項目，symfony，設置相關聯。

你有啟用iconv擴展名嗎？

請發布此命令的回復：

php -i | grep -i "iconv support"

或者，在php.ini文件中搜索“extension = iconv.so”，如果已注釋掉，則取消注釋並確保重新啟動Apache。

如果失敗，請嘗試安裝composer包：

composer require symfony/polyfill-iconv
