PHP composer安装问题

Question

我对php composer有一个很大的问题，我运行这个命令

php composer.phar install

但是它向我显示了这个错误

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-install-cmd event terminated with an exception


  [RuntimeException]
  An error occurred when executing the "'cache:clear --no-warmup'" command:
  PHP Warning:  require_once(/var/www/lcp-api/app/bootstrap.php.cache): failed to open stream: No such file or directory in /var/www/lcp-api/app/console on line 10
  PHP Fatal error:  require_once(): Failed opening required '/var/www/lcp-api/app/bootstrap.php.cache' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/
  lcp-api/app/console on line 10
  .

我检查了文件composer.json，看起来一切正常

"post-install-cmd": [
      "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::removeSymfonyStandardFiles",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget"
    ],
    "post-update-cmd": [
      "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::removeSymfonyStandardFiles",
      "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget"
    ]
  },

你知道为什么我会得到这个错误吗？

你的bootstrap.php.cache文件好像不见了。Symfony有时会发生这种情况。

如果运行的是composer update而不是install，则应重新生成该文件。如果这不起作用，您可以通过从项目的根目录运行以下命令来手动生成：

php vendor/sensio/distribution-bundle/Sensio/Bundle/DistributionBundle/Resources/bin/build_bootstrap.php

如果这也不起作用，您可以尝试通过运行composer来强制环境进入生产模式，如下所示：

SYMFONY_ENV=prod composer install

请记住，如果在开发环境中执行此操作，调试模式将被禁用。这将生成一个bootstrap.php.cache文件，因此您应该能够再次在开发模式下重新运行composer。
