PHP Composer - 无法在macOS Sierra上安装composer

Question

我正在尝试安装运行getcomposer.org/download文档站点上提供的命令的composer:

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

但是我收到一条错误消息:

Warning: copy(): SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed in Command line code on line 1

Warning: copy(): Failed to enable crypto in Command line code on line 1

Could not open input file: composer-setup.php

我也试图在全球范围内安装它,但我无法摆脱这个消息.请帮助D:

Answer 1

我有同样的问题,但这就是我所做的:

• 我将其复制粘贴到终端php -r "copy('http://getcomposer.org/installer', 'composer-setup.php');"上的终端,该终端将作曲家下载到您当前所在的目录.

(问题是因为https protocol)

• 然后 php composer-setup.php --install-dir=/usr/local/bin --filename=composer运行此命令,将Composer安装到我的bin文件夹,以便我可以全局运行它.

• 然后你必须取消作曲家的链接 php -r "unlink('composer-setup.php');"

• 最后检查一下安装的Composer composer -V.

祝好运 !

Answer 2

我有同样的问题，但这就是我所做的：

• 我curl -sS https://getcomposer.org/installer | php在我的终端上运行，这使作曲家安装在我的电脑上。
• 然后我将 Composer 移动到我的 bin 文件夹中，以便我可以在全局范围内运行它mv Composer.phar usr/local/bin/composer。
