教条/dbal未在Heroku安装

Question

我在Heroku上经营着一个Laravel项目。为了运行一个将改变列类型的迁移，我需要安装dbal/dbal包。我在"doctrine/dbal": "^2.5"对象中的composer.json中插入了"require"行。

当我把更改推给Heroku时，它显示了这条线。

- Installing doctrine/dbal (v2.5.5)
  Downloading: 100%

在那之后，当我运行heroku run composer show doctrine/dbal时，它就显示出来了。

[InvalidArgumentException]
Package doctrine/dbal not found

在那之后，我还运行了几次heroku run composer update。这是我的命令的完整日志。

所以，问题是在我把回购推给Heroku之前，composer.lock并没有被更新。

Heroku只在读取锁文件以安装包的composer install之后运行git push。正如克里斯在评论中指出的

不要费心在Heroku上运行作曲家更新程序。编译后对本地文件系统所做的任何更改都将在Dyno循环之后丢失。

因此，最佳实践是，在本地文件系统中编辑composer.json之后，始终运行composer update，然后运行git push。

我把"doctrine/dbal": "^2.5"从"require-dev"转到了"require"，在推之前没有运行composer update，这就是问题的原因。
