1. 失败经历
安装 easyswoole 的过程中,发现无法通过 composer 安装
报错信息如下:
ubuntu@VM-0-9-ubuntu:~/demo/easyswoole$ composer require easyswoole/easyswoole=3.x
./composer.json has been created
Loading composer repositories with package information
Updating dependencies (including require-dev)
Installation failed, deleting ./composer.json.
[ErrorException]
"continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?
require [--dev] [--prefer-source] [--prefer-dist] [--no-plugins] [--no-progress] [--no-update] [--update-no-dev] [--update-with-dependencies] [--ignore-platform-reqs] [--sort-packages] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--] [<packages>]..
google 一下,没有对应的错误信息。想着先查看一下 composer 版本
发现:composer 版本过低,就顺便升级 composer 升级了再说。
ubuntu@VM-0-9-ubuntu:~/demo/easyswoole$ composer -V
Composer version @package_branch_alias_version@ (1.0.0-beta2) 2016-03-27 16:00:34
升级的过程中发现,升级失败。老版本的 composer 不能自动升级
ubuntu@VM-0-9-ubuntu:~$ composer self-update
[InvalidArgumentException]
Command "self-update" is not defined.
看来是 composer 包太低,都没有自动升级的功能
2. 下载新的 composer 包
1. 新增最新的 composer
wget https://dl.laravel-china.org/composer.phar -O /usr/local/bin/composer
sudo chmod a+x /usr/local/bin/composer
然后把脚本 覆盖到原来的(通过软链)
2. 查看原来的位置
sudo mv /usr/bin/composer /tmp/
sudo ln -s /usr/local/bin/composer /usr/bin/composer
ubuntu@VM-0-9-ubuntu:~$ composer -V
Composer version 1.8.5 2019-04-09 17:46:47
3. 安装
使用 composer 安装项目
