使用代理解决composer不能连接,缓慢等问题

1.检查composer配置 输入 composer diagnose 出现如下错误

MacBook-Pro:mobile me$ composer diagnose

diagnose

2.mac下配置终端代理

$ export http_proxy='http://127.0.0.1:1080' # 配置http访问的
$ export https_proxy='http://127.0.0.1:1080' # 配置https
$ export ALL_RPOXY='http://127.0.0.1:1080' # 配置http和https访问

3.composer.json文件中增加取消https验证

1.直接修改项目中的composer.json
"config": {
        "secure-http": false
    },
2.或者直接全局取消https验证
composer config -g secure-http false

4.取消代理设置

$ unset http_proxy
$ unset https_proxy
$ unset ALL_RPOXY

win10 配置composer代理

方法同 2.3.4 我使用的 git bash 脚本命令执行的
查看变量 使用  echo $http_proxy
