# root @ www.axinblog.com in /home/wwwroot/axinblog on git:develop x [19:08:55] $ composer require web3p/ethereum-tx Do not run Composer as root/super user! See https://getcomposer.org/root for details Continue as root/super user [yes]? yes Using version ^0.4.3 for web3p/ethereum-tx ./composer.json has been updated Running composer update web3p/ethereum-tx Loading composer repositories with package information Updating dependencies Your requirements could not be resolved to an installable set of packages.
Problem 1 - simplito/elliptic-php[1.0.6, ..., 1.0.9] require ext-gmp * -> it is missing from your system. Install or enable PHP's gmp extension. - web3p/ethereum-tx 0.4.3 requires simplito/elliptic-php ~1.0.6 -> satisfiable by simplito/elliptic-php[1.0.6, 1.0.7, 1.0.8, 1.0.9]. - Root composer.json requires web3p/ethereum-tx ^0.4.3 -> satisfiable by web3p/ethereum-tx[0.4.3].
To enable extensions, verify that they are enabled in your .ini files: - /usr/local/php/etc/php.ini - /usr/local/php/conf.d/007-redis.ini You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
环境说明
Ubuntu 18.04.6 LTS
LNMP 1.8
PHP 7.3.28 & PHP 8.0.8 均测试通过
步骤说明
安装 GMP 开发库
sudo apt-get install libgmp-dev
安装 PHP GMP 扩展
安装
$ cd ~/lnmp1.8/src $ tar jxvf php-7.3.28.tar.bz2 $ cd php-7.3.28/ext/gmp $ /usr/local/php/bin/phpize $ ./configure --with-php-config=/usr/local/php/bin/php-config $ make && make install
这里没装GMP 开发库
会报错
configure: error: Unable to locate gmp.h
启用扩展
/usr/local/php/etc/php.ini
;extension=gmp 改 extension=gmp
重启LNMP
lnmp reload
查看是否启用成功
$ php -m | grep gmp gmp
问题解决
sc0vu/web3.php 0.1.4 requires php ^7.1 -> your php version (8.0.8) does not satisfy that requirement.
