Question

我使用的是Ubuntu 16.04 LTS

PHP 7.0.13 NetBean

我尝试在NetBeans环境中运行与composer链接的一些操作我有这些日志

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

问题与我的项目，symfony，设置有关。

Answer 1

您是否启用了iconv扩展程序？

请发布此命令的回复：

php -i | grep -i "iconv support"

或者，在php.ini文件中搜索“extension = iconv.so”，如果已注释掉，请取消注释，并确保重新启动Apache。

如果失败，请尝试安装composer软件包：

composer require symfony/polyfill-iconv

致命错误：未捕获错误：在phar中调用未定义的函数Symfony \ Polyfill \ Mbstring \ iconv（）：
