composer-php 安装失败 laravel

Question

我正在尝试将 laravel 项目移动到远程服务器。我只是复制 public/html 文件夹中的文件夹，然后我尝试按照此处所述安装作曲家： https://getcomposer.org/download/

使用第一个命令我看到了这个错误：

/federlegno$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" PHP Warning: copy(): SSL operation failed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed in Command line code on line 1 PHP Warning: copy(): Failed to enable crypto in Command line code on line 1 PHP Warning: copy(https://getcomposer.org/installer): failed to open stream: operation failed in Command line code on line 1

作为解决方案，我找到运行没有 https 的命令：php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

然后似乎其他命令有效，没有提示任何错误（我什至尝试使用浏览器访问 link，它有效！）。

然后当我尝试运行:

composer install

在 laravel 文件夹中出现此错误：

bash: composer: command not found

一些附加信息：

/federlegno$ php -r "phpinfo();" | grep OpenSSL SSL Version => OpenSSL/1.0.2r OpenSSL support => enabled OpenSSL Library Version => OpenSSL 1.1.0j 20 Nov 2018 OpenSSL Header Version => OpenSSL 1.1.1a 20 Nov 2018 Native OpenSSL support => enabled

您应该将 composer.phar 文件（由安装脚本下载）移动到 /usr/local/bin 或 /usr/bin 目录

sudo mv composer.phar /usr/local/bin/composer

或

sudo mv composer.phar /usr/bin/composer
