php - Composer 无法解码响应 : zlib_decode()

Question

我正在尝试安装 crudkit.com。这是我的 composer.json:

{
    "description" : "The CodeIgniter framework",
    "name" : "codeigniter/framework",
    "license": "MIT",
    "require": {
        "php": ">=5.2.4"
    },
    "require-dev": {
        "mikey179/vfsStream": "1.1.*"
    }

}

之后，我使用以下命令运行 Composer :

$ sudo php composer.phar install

但我得到了这样的错误:

Installing dependencies (including require-dev)
Failed to decode response: zlib_decode(): data error
Retrying with degraded mode, check https://getcomposer.org/doc/articles/troubleshooting.md#degraded-mode for more info

有谁知道如何解决它？

更新:
我尝试 Composer 诊断，我得到了这个:

Checking composer.json: FAIL
The version field is present, it is recommended to leave it out if the package is published on Packagist.
Checking platform settings: FAIL
The OpenSSL library (0.9.8zc) used by PHP does not support TLSv1.2 or TLSv1.1.
If possible you should upgrade OpenSSL to version 1.0.1 or above.

Answer 1

尝试更新 Composer 如下。

sudo composer clear-cache

将此行添加到 composer.json

"repositories": [
    {
        "type": "composer",
        "url": "https://packagist.org"
    },
    { "packagist": false }
],

进而

sudo composer update
