在Elastic Beanstalk中运行时出现迁移迁移错误 [英] Sequelize migrations error while running in Elastic Beanstalk

问题描述

我正在尝试让Sequelize迁移在每次部署到Elastic Beanstalk时运行.

I'm trying to get Sequelize migrations to run on each deploy to Elastic Beanstalk.

我正在遵循 -vars-how-to-ac>有关Stack Overflow的其他答案，甚至是我过去从事过的其他项目，并且正在/.ebextensions文件夹中使用.config文件:

I'm following the advice of the documentation, of other answers on Stack Overflow, and even a different project I've worked on in the past, and am using a .config file in my /.ebextensions folder:

container_commands:
    00_node_binary:
        command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/node /bin/node"
    01_npm_binary:
        command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/npm /bin/npm"
    03_db_migrate:
        command: ./node_modules/.bin/sequelize db:migrate
        leader_only: true

当我尝试运行它时，出现此错误:

When I try to run it, I get this error:

ERROR   [Instance: i-06991b5ec3283038a] Command failed on instance. Return code: 127 Output: /bin/sh: ./node_modules/.bin/sequelize: No such file or directory.

我还需要做什么(在.extensions，.elasticbeanstalk文件或EB的软件配置设置中)，以便EB可以找到该模块并运行此命令?

What else do I need to do (either in .extensions, in .elasticbeanstalk file, or in EB's Software Configuration settings) so EB can find this module and run this command?

注意:上面的ls -td命令在我之前的项目中产生了以下结果:

Note: The ls -td commands above produce this result in my previous project:

/opt/elasticbeanstalk/node-install/node-v6.9.1-linux-x64

/opt/elasticbeanstalk/node-install/node-v6.9.1-linux-x64

这导致当前项目出现问题:

And this result in the current project I'm having trouble with:

/opt/elasticbeanstalk/node-install/node-v10.17.0-linux-x64

/opt/elasticbeanstalk/node-install/node-v10.17.0-linux-x64

推荐答案

我通过在.ebextension/config_file.sh

文件:

"/opt/elasticbeanstalk/hooks/appdeploy/pre/config_file.sh":

"/opt/elasticbeanstalk/hooks/appdeploy/pre/config_file.sh":

mode: "000755"
owner: root
group: root
content: |
  #!/bin/bash
  
  curl --silent --location https://rpm.nodesource.com/setup_12.x | sudo bash -
  
  sudo yum -y install nodejs

---

然后

---

then

在应用程序目录中的终端上运行命令:

run command on terminal in your app directory:

./node_modules/.bin/sequelize db:migrate

它对我有用！
