疑难解答“require_once(../bootstrap.php.cache)：打开流失败：没有这样的文件或目录”答案

【问题标题】：Troubleshooting "require_once(../bootstrap.php.cache): failed to open stream: No such file or directory"疑难解答“require_once(../bootstrap.php.cache)：打开流失败：没有这样的文件或目录”
【发布时间】：2012-08-11 02:04:32
【问题描述】：

我正在尝试重新部署我一直在处理的 Symfony 2.1x 项目，而 app_dev.php 失败了，因为它找不到 app/bootstrap.php.cache。由于我使用了 Symfony2 的推荐 .gitignore 文件，所以在项目的 git 存储库中省略了这个文件：

# .gitignore
/app/bootstrap*

我认为app/bootstrap.php.cache 是在$ php composer.phar install 过程中生成的是否正确？如果是这种情况，那么我将为您提供我的composer.json：

如何生成bootstrap.php.cache？

【问题讨论】：

首先你应该检查你是否对你的文件和文件夹有正确的权限。
缓存文件随 symfony 一起提供。你检查过你的应用目录吗？你有没有把它删掉？ app_dev.php 中的路径是否指向正确的目录？应用/控制台是否有效？
我确实删除了目录的内容，然后尝试将项目从其 git 存储库重新部署回其中。如果bootstrap.php.cache 不打算在仓库中，它如何在从 git 部署后添加回项目中？我仍然认为它是在作曲家安装过程中完成的，但如果有人知道更好，请赐教。

【解决方案1】：

只需转到您的项目并使用 composer 生成它

php /path/to/composer/composer.phar install

【讨论】：

在运行此命令之前稍等片刻：您真的要更新您的供应商吗？ composer.phar install 命令将创建您正在寻找的缺少的 bootstrap.php.cache 文件，并且不会修改您的供应商版本。
你可能想要composer update --lock，因为它确实触发了后步骤，但实际上并没有更新任何依赖项。

【解决方案2】：

只需运行以下命令。

php composer.phar install

【解决方案3】：

您已经复制了 post-install-cmd 和 post-updated-cmd，而您应该已将 MopaBootstrapBundle 脚本添加到现有密钥。尝试以下 composer.json 并重新运行php composer.phar install

【讨论】：

这绝对是问题的一部分，我感谢你。

【解决方案4】：

在我的例子中，我的作曲家版本是 2.x，所需的版本是 1.x 所以，首先我需要降级到版本 1，然后我运行 composer install

sudo composer self-update --1 && composer install -v --prefer-dist
