Laravel执行migrate操作提示”Class not found”怎么解决

Jun 08, 2016 pm 05:19 PM
autoload composer migrate nbsp

Class not found提示是类没有找到了,没有找到对应的类我们可以检查是不是哪里配置或调用有问题了,下面我们来看一篇关于Laravel执行migrate操作提示”Class not found”问题解决办法了,具体的如下所示。

<script>ec(2);</script>

使用Laravel的artisan命令工具执行migrate操作,提示”Class not found”的错误,但是这个migrate类文件是存在的,如遇到这个问题,可执行以下composer dump-autoload,问题得到解决。

一开始报错如下:


[root@iZ94r80gdghZ tanteng.me]# php artisan migrate:reset
                                                          
[Symfony\Component\Debug\Exception\FatalThrowableError] 
Fatal error: Class 'CreateAttachmentTable' not found

无论执行migrate什么操作都提示类找不到。

执行composer dump-autoload后,再次运行migrate操作,一切正常。

[root@iZ94r80gdghZ tanteng.me]# composer dump-autoload
Generating autoload files
[root@iZ94r80gdghZ tanteng.me]# php artisan migrate:reset

composer dump-autoload的作用

composer dump-autoload命令的作用是优化自动加载,当把代码部署到生产环境中,或者增加删除了自动加载文件夹里的类文件,需要执行一下自动加载命令,这样自动加载才会起作用。

Composer's advanced features: aliases, scripts, and conflict resolution Composer's advanced features: aliases, scripts, and conflict resolution Jun 03, 2024 pm 12:37 PM

Composer provides advanced features, including: 1. Aliases: define convenient names for packages for repeated reference; 2. Scripts: execute custom commands when installing/updating packages, used to create database tables or compile resources; 3. Conflict resolution: use priorities Rules, satisfaction constraints, and package aliases resolve the different requirements of multiple packages for the same dependency version to avoid installation conflicts.

Agile development and operation of PHP microservice containerization Agile development and operation of PHP microservice containerization May 08, 2024 pm 02:21 PM

Answer: PHP microservices are deployed with HelmCharts for agile development and containerized with DockerContainer for isolation and scalability. Detailed description: Use HelmCharts to automatically deploy PHP microservices to achieve agile development. Docker images allow for rapid iteration and version control of microservices. The DockerContainer standard isolates microservices, and Kubernetes manages the availability and scalability of the containers. Use Prometheus and Grafana to monitor microservice performance and health, and create alarms and automatic repair mechanisms.

PHP code version control and collaboration PHP code version control and collaboration May 07, 2024 am 08:54 AM

PHP code version control: There are two version control systems (VCS) commonly used in PHP development: Git: distributed VCS, where developers store copies of the code base locally to facilitate collaboration and offline work.

The role of PHP CI/CD in DevOps projects The role of PHP CI/CD in DevOps projects May 08, 2024 pm 09:09 PM

PHPCI/CD is a key practice in DevOps projects that automates the build, test, and deployment processes to improve development efficiency and software quality. A typical PHPCI/CD pipeline consists of the following stages: 1) Continuous Integration: Whenever the code changes, the code is automatically built and tested. 2) Continuous deployment: Speed ​​up delivery by automatically deploying tested and integrated code to the production environment. By implementing the PHPCI/CD pipeline, you can increase development efficiency, improve software quality, shorten time to market, and improve reliability.

How to use PHP CI/CD to iterate quickly? How to use PHP CI/CD to iterate quickly? May 08, 2024 pm 10:15 PM

Answer: Use PHPCI/CD to achieve rapid iteration, including setting up CI/CD pipelines, automated testing and deployment processes. Set up a CI/CD pipeline: Select a CI/CD tool, configure the code repository, and define the build pipeline. Automated testing: Write unit and integration tests and use testing frameworks to simplify testing. Practical case: Using TravisCI: install TravisCI, define the pipeline, enable the pipeline, and view the results. Implement continuous delivery: select deployment tools, define deployment pipelines, and automate deployment. Benefits: Improve development efficiency, reduce errors, and shorten delivery time.
