如何修复“ https://repo.packagist.org/packages.json不包含有效的Json”？

问题描述

我在vagrantbox（Centos 7）上运行的作曲家遇到问题，这种情况开始突然发生。

I've an issue with composer running on a vagrantbox (Centos 7), which started to just suddenly happen.

我已经尝试过手动运行命令/解决方案在下面的链接中提及，但无济于事。

I've already tried manually running the command/solution mentioned on the link below but to no avail.

（为了澄清， 我正在使用无业游民而不是码头工人 ，但这是我所遇到的最接近的问题。我发现的大多数信息都与composer.json无效有关，但这里是packagist.org/packages.json，目前有效）

(To clarify, i'm using vagrant not docker, but it was the closest question i found to my situation. Most of the information i found are related to composer.json not being valid, but here is packagist.org/packages.json which, is currently valid)

以下是问题的详细信息。

Here are the details of the issue.

在终端机上运行 composer更新时，我得到：

While running composer update on terminal i get:

 composer update


  [Seld\JsonLint\ParsingException]
  "https://repo.packagist.org/packages.json" does not contain valid JSON
  Parse error on line 1:

  ^
  Expected one of: 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['

并且在运行还在终端上的composer install 每个软件包都返回以下内容：

And when running composer install also on terminal every package returns this:

Failed to download psr/cache from dist: "https://api.github.com/repos/php-fig/cache/zipball/d11b50ad223250cf17b86e38383413f5a6764bf8"
appears broken, and returned an empty 200 response
    Now trying to download from source

运行 composer config --global repo.packagist作曲家packagist.org
现在是结果

When running composer config --global repo.packagist composer packagist.orgthe results are now

composer update
Loading composer repositories with package information


  [Composer\Downloader\TransportException]
  Your configuration does not allow connections to http://repo.packagist.org/packages.json. See https://getcomposer.o
  rg/doc/06-config.md#secure-http for details.

任何想法为什么会开始发生，我该如何解决？

Any ideas why this started to happen, how can i fix it?

推荐答案

此处存在相同的问题，因为php更新至7.2.17。
在具有php 7.2.16的composer的centos 7上运行得很好...
现在回滚到7.2.16是找到的唯一解决方案...

same problem here, since php updated to 7.2.17.On a centos 7 with php 7.2.16 composer run just fine...Rollback to 7.2.16 is for now the only solution found...

似乎是symfony flex问题：
