记一次 Composer 问题的解决过程！！

Jourdon 的个人博客 / 5459 / 1 / 创建于 5年前 / 更新于 5年前

快下班的时候准备新搞个小项目本地测试，随手就是一个composer

composer create-project laravel/laravel laravel --prefer-dist

结果一个鲜红的错误

[RuntimeException]
  Could not scan for classes inside "/home/vagrant/code/laravel/vendor/sebastian/diff/src/" which does not appear to be a file nor a folder

跑去目录看了下，sebastian/diff 是空的，看来是没有下载完整。

最近composer镜像总是有问题，加上vvv看看吧。
镜像确实走的https://packagist.laravel-china.org,但是laravel的每一个包似乎都在报错，随便放一两个上来，

  - Installing laravel/tinker (v1.0.7): Loading from cache

什么情况？镜像出错了？好吧，去掉镜像，再来看下，

vagrant@homestead:~/code$ composer config -g -l
[repositories.packagist.org.type] composer
[repositories.packagist.org.url] https?://repo.packagist.org
[repositories.packagist.org.allow_ssl_downgrade] true

现在用官方镜像试试，SS要开启来。（穷人只有免费试用:joy::joy::joy:）
file

结果还是一样！！！
怎么的，今天packagist全挂了？试试安装个扩展包吧

vagrant@homestead:~/code/test$ composer require "overtrue/laravel-wechat"
Using version ^4.0 for overtrue/laravel-wechat
./composer.json has been updated

FxxK , 什么情况？扩展包可以新项目就不行？百度google全找了下，居然没有！！！！
突然想到每次开homestead都会提醒我的

==> homestead-7: A newer version of the box 'laravel/homestead' for provider 'virtualbox' is
==> homestead-7: available! You currently have version '6.0.0'. The latest is version
==> homestead-7: '6.1.0'. Run `vagrant box update` to update.

OK.我来升级吧,反正没事做就死马当活马医吧...
漫长的等待后...

➜  Homestead git:(860e3cd) vagrant box update
==> homestead-7: Checking for updates to 'laravel/homestead'
    homestead-7: Latest installed version: 6.0.0
    homestead-7: Version constraints: >= 5.2.0
    homestead-7: Provider: virtualbox
==> homestead-7: Updating 'laravel/homestead' with provider 'virtualbox' from version
==> homestead-7: '6.0.0' to '6.1.0'...
==> homestead-7: Loading metadata for box 'https://vagrantcloud.com/laravel/homestead'
==> homestead-7: Adding box 'laravel/homestead' (v6.1.0) for provider: virtualbox
    homestead-7: Downloading: https://vagrantcloud.com/laravel/boxes/homestead/versions/6.1.0/providers/virtualbox.box
==> homestead-7: Box download is resuming from prior download progress
==> homestead-7: Successfully added box 'laravel/homestead' (v6.1.0) for 'virtualbox'!
➜  Homestead git:(860e3cd) vagrant box list
laravel/homestead (virtualbox, 6.0.0)
laravel/homestead (virtualbox, 6.1.0)

现在有两个box了，这里吐槽下virtualbox的升级，明明是update,结果是新加了一个box进来，你在搞笑吗？？这逻辑也是棒棒的！
vagrant也一起升级了算球。
file

➜  Homestead git:(860e3cd) vagrant version
Installed Version: 2.1.2
Latest Version: 2.1.2

You're running an up-to-date version of Vagrant!

重新来启动homestead吧,又是经过漫长的等待，终于进虚拟机了（新加了一个virtualbox,启动会以最新版本启动，所以初始化比正常启动要慢！）

重新安装个laravel项目，终于看到了熟悉的画面

这个小问题终于解决了。

回过头来想一下，是哪里出了问题呢？

不知道，没想明白，那么问题来了：
