Composer 提示 zlib_decode (): data error

下面由composer命令使用教程欄目記錄一下解決這個(gè)問題的方法，遇到有幾次了，印象中每次解決的方法都不一樣

環(huán)境說明

CentOS Linux 7 PHP 5.6.36 Composer 1.8.6

調(diào)試過程

Round One

一看到這個(gè)問題，首先看了一下 composer 版本，不是最新版本，升級(jí)一下吧

$ composer self-update   [SymfonyComponentConsoleExceptionCommandNotFoundException]     Command "self-update" is not defined.

命令不存在，想了一下，我的用戶好像權(quán)限不足，算了吧。。。。

Round Two

Google 一下，搜索結(jié)果第一條的解決方案是換源，本來用的是阿里云的源，換一下吧

$ composer config repo.packagist composer http://packagist.phpcomposer.com

換個(gè)鏡像之后，composer.json 長(zhǎng)這樣

{     "license": "proprietary",     "require": {         "php": ">=5.6",         "guzzlehttp/guzzle": "^6.3",         "aws/aws-sdk-php": "^3.52"     },     "autoload": {         "psr-4": {             "Rpc\": "application/library/Rpc/"         }     },     "repositories": {         "packagist": {             "type": "composer",             "url": "http://packagist.phpcomposer.com"         }     } }

安裝

不支持 http 只支持 https，想了想還是不改這個(gè)配置吧，不止我一個(gè)人用這臺(tái)機(jī)。。。。

Round Three

我想了下，既然是國(guó)外的服務(wù)器，我干脆直接把鏡像源全去了，都用默認(rèn)的，說干就干

composer config -g --unset repos.packagist composer config --unset repos.packagist composer clearcache composer diagnose composer install -vvv

然后安裝，直接安裝成功了？？？我還沒反應(yīng)過來。由于 composer install -vvv 輸出的日志太長(zhǎng)了，不太方便截圖，放一個(gè) composer install 的輸出截圖

結(jié)論

本次問題的解決方法是去掉所有的鏡像源，直接用默認(rèn)的鏡像源安裝，應(yīng)該只適用于國(guó)外的服務(wù)器。
