centos 7 下安装composer

[root@VM_0_8_centos ~]# curl -sS https://getcomposer.org/installer | php
All settings correct for using Composer
Downloading...
 
Composer (version 1.8.6) successfully installed to: /root/composer.phar
Use it: php composer.phar
mv composer.phar /usr/local/bin/composer

注意： 如果上诉命令因为权限执行失败， 请使用 sudo 再次尝试运行 mv 那行命令。

现在只需要运行 composer 命令就可以使用 Composer 而不需要输入 php composer.phar。

composer的install和require和update指令的区别

注意:对于 require 和 install 是不相同的，require 会把包的信息添加到 composer.json 文件中并进行 install 。而 install 是直接从 composer.json 或 composer.lock 文件中提取依赖信息，然后进行安装。

安装composer时出现 Failed to decode zlib stream 这个错误
打开这个目录里的php.ini文件,修改zlib.output_compression = Off 修改为 On

修改设置镜像地址,加速安装

①composer config -g repo.packagist composer https://packagist.phpcomposer.com
①composer config -g repo.packagist composer https://packagist.laravel-china.org

composer软件更新到最新的版本

composer self-update

composer回滚到上次安装的版本

composer self-update --rollback

安装指定版本的composer

composer self-update 2.0.10

composer require topthink/think-queue v2.0.4
要求

topthink/think-helper: >=1.0.4
topthink/think-installer: ^2.0
topthink/framework: 5.1.*

当前版本 “topthink/framework”: “~5.0.24”,所以安装时,会报错.

安装指定版本的扩展包

composer require package $version
composer require topthink/think-queue v1.1.6

创建一个thinkphp项目并且指定路径

composer create-project topthink/think $path
composer create-project topthink/think v5.1.36

执行命令composer require topthink/think-queue v2.0.4如下:
D:\phpStudy1\WWW\tp5.1.36\v5.1.36>composer require topthink/think-queue v2.0.4
./composer.json has been updated

执行命令后会在D:\phpStudy1\WWW\tp5.1.36\v5.1.36\vendor\topthink\think-queue创建think-queue扩展包.

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

# 取消全局配置
composer config -g –unset repos.packagist

报错：

解决方案：
换http源，更改配置不要使用https加密连接

 composer config -g repo.packagist composer http://packagist.phpcomposer.com
 composer config -g secure-http false

composer require安装报错 No driver found to handle VCS repository
解决方案 将版本切换到 2.0.10 安装依赖包成功

The “topthink/think-installer” plugin was skipped because it requires a Plugin API version (“^1.0”) that does not match your Composer installation (“2.0.0”). You may need to run composer update with the “–no-plugins” option.
解决方案 回滚到composer版本1，只需执行以下命令：
composer self-update –1

当您想回到版本2时（在更新或删除不兼容的插件之后，您应该这样做）：
composer self-update –2

指定php版本安装包

Potential causes:

 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
 - It's a private package and you forgot to add a custom repository to find it

composer版本2.0.14 重新设置镜像网站后解决了

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

使用报错 it could not be found in any version, there may be a typo in the package name,修改下镜像源

 composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
