Composer安装实际上并不安装库

Question

问题

这很奇怪.我只是将它添加到我的composer.json文件中:

"maatwebsite/excel": "~2.1.0"

然而,当我运行时composer install,该库未安装:

composer show | grep excel

没有回报.

因此,每次运行部署脚本时,都会出现此错误:

> php artisan clear-compiled
PHP Fatal error:  Uncaught Symfony\Component\Debug\Exception\FatalThrowableError: Class 'PHPExcel_Shared_Font' not found in /Users/Shared/dev/php/toters-api/config/excel.php:182

Symfony\Component\Debug\Exception\FatalThrowableError: Class 'PHPExcel_Shared_Font' not found in /Users/Shared/dev/php/toters-api/config/excel.php on line 182

这是一个预期的错误,因为Composer忽略了我的maatwebsite/excel库!

解决方法

我使用这些步骤来强制它进入工作状态:

rm -rf vendor
rm composer.lock
composer install --no-scripts

但这显然是一个丑陋而昂贵的黑客攻击(我已经将其添加为envoyer自动部署中的预挂钩),并且它每次都有效,但它为自动部署过程增加了很多时间.

参考

• 我的composer.json文件
• 我的composer.lock文件

题

我如何运行一个强制它工作的Composer命令(但我也必须避免使用该composer update命令,因为我不希望在每次部署期间更新所有库,因为这会导致对我的代码库进行不可预测的更新)

更新

我刚刚注意到我们版本上的这个库支持旧版本的PHP - 可能与它有关吗？

运行composer require maatwebsite/excel返回以下内容:

这很奇怪,因为它应该支持Laravel 5.3(我的Laravel):

但我的PHP版本是7.1.

Answer 1

composer install不喜欢npm install.我很确定你是否手动添加了一个像你一样被忽略的软件包,就像composer.lock已经存在的一样.

• 做composer update会有效.
• 或者通过执行添加包 composer require maatwebsite/excel
• 或者删除composer.lock然后运行composer install

编辑:

composer require maatwebsite/excel将尝试安装该软件包的最新版本,但因为您正在使用laraval v5.3.31,所以应该安装maatwebsite/excel ~2.1.0.版本3适用于laraval ^5.5

• composer require "maatwebsite/excel:~2.1.0"
