当尝试在AfterInstall事件上运行脚本时，我收到：

LifecycleEvent - AfterInstall
Script - deploy/install_dependencies.sh
[stdout]Install dependencies. /
[stderr]/usr/bin/env: node: No such file or directory

，这很奇怪，因为：

1. 哪个节点产生：~/. nvm/version/node/v15.2.0/bin/node
2. npm产生的：~/. nvm/version/node/v15.2.0/bin/npm

appspec. yml不是我设置的，但我认为它很简单：

version: 0.0
os: linux
files:
  - source: /
    destination: /home/ec2-user/deploy/
permissions:
  - object: /
    pattern: "**"
    owner: ec2-user
hooks:
  AfterInstall:
    - location: deploy/install_dependencies.sh
    - location: deploy/build.sh
    - location: deploy/install_prd_dependencies.sh
    - location: deploy/copy_overwrite.sh
    # - location: deploy/migrations.sh
      timeout: 300
      runas: ec2-user
  ApplicationStart:
    - location: deploy/start_server.sh
      timeout: 300
      runas: ec2-user

我在阅读后添加了runas： ec2-user和权限键及其值：在AfterInstall Hook中启动节点应用程序，虽然不是同一个问题，似乎可以解决我的问题，但它没有。

我检查了是否安装了nvm发出哪个nvm，它不起作用：

[ec2-user@my-ip ~]$ which nvm
/usr/bin/which: no nvm in (/home/ec2-user/.nvm/versions/node/v15.2.0/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/ec2-user/.local/bin:/home/ec2-user/bin)

但是，只发出nvmI recevienvm的CLI帮助命令没有任何问题。

我检查了ec2-user的. bashrc以查看是否正确导出了nvm（如本答案所示）：

# User specific aliases and functions

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

所有脚本都对npm/node二进制文件使用绝对路径，示例：

install_dependencies.sh

#!/bin/bash

echo "Install dependencies. $(pwd)"
cd /home/ec2-user/deploy/

/home/ec2-user/.nvm/versions/node/v15.2.0/bin/npm install

start_server.sh

#!/bin/bash

echo "Restarting servers..."

/home/ec2-user/.nvm/versions/node/v15.2.0/bin/pm2 restart 0

codedpeloy是否使用rootuser来发出这些命令，即使为ec2-user设置了runas？我不明白发生了什么，它以前工作过。
