除非手动执行，否则 Elastic Beanstalk 上的“npm install”会失败

【中文标题】除非手动执行，否则 Elastic Beanstalk 上的“npm install”会失败

【英文标题】："npm install" on Elastic Beanstalk fails unless manually executed

【问题描述】：

我有一个带有 php 应用程序的 Elastic Beanstalk 环境。我想在部署我的应用程序后运行npm install。

node 和 npm 都通过部署配置安装在服务器上。我已经定义了一个容器命令来简单地 cd 进入正确的目录，然后运行 ​​npm install，但它 always 失败并出现相同的错误。

如果我手动执行npm install，一切都会完美安装。

我该如何调试这个？

deploy.config

commands:
    01_mkdir_webapp_dir:
      # use the test directive to create the directory
      # if the mkdir command fails the rest of this directive is ignored
      test: 'mkdir /home/webapp'
      command: 'ls -la /home/webapp'
    02_chown_webapp_dir:
      command: 'chown webapp:webapp /home/webapp'
    03_chmod_webapp_dir:
      command: 'chmod 700 /home/webapp'
    04_node_install:
        cwd: /tmp
        test: '[ ! -f /usr/bin/node ] && echo "node not installed"'
        command: 'yum install -y nodejs --enablerepo=epel'
    05_npm_install:
        cwd: /tmp
        test: '[ ! -f /usr/bin/npm ] && echo "npm not installed"'
        command: 'curl -L http://npmjs.org/install.sh | sh'
    06_node_update:
        cwd: /tmp
        test: '[ ! -f /usr/bin/n ] && echo "node not updated"'
        command: 'npm install -g n && n stable'

# These commands will be run just before the application is started
container_commands:
    01_npm_build:
        cwd: '/var/app/ondeck/wp-content/themes/gift-certificates'
        command: 'npm install && npm run build'

【问题讨论】：

您是否在日志中看到这些行：npm WARN optional Skipping failed optional dependency /chokidar/fsevents: npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.14

是的，但这只是一个“WARN”级别的日志。我读到的所有内容都是可以忽略 fsevents（尽管您可能比我更了解它）

嗯。另一个嫌疑人是“node-sass”。也许以下链接对您有帮助github.com/sass/node-sass/issues/1504

我也遇到了同样的问题。 npm install 在我 ssh 进入实例时有效，但不是来自 .ebextensions/02env.config。你有没有深入了解这个@AlecSanger

@andreobrown 我相信这个特殊问题与两件事有关：1：在 Amazon Linux PHP Elastic Beanstalk 实例上获取节点的更新版本显然非常困难，如果你只是用百胜安装。 2：如果您使用的是微型实例，node-sass 构建可能会超时。将我的服务器大小提升到至少 t2.small 让我超越了这一点。希望对您有所帮助！

【参考方案1】：

对于在 PHP Elastic Beanstalk 实例上遇到此问题的其他人，以下是帮助我解决此问题的方法：

1) 如果您在 Amazon Linux 实例上运行，则执行yum install nodejs 将为您提供一个极有可能与许多东西不兼容的超级旧版本。我必须在我的.ebextensions 目录中添加一个脚本并从我的一个配置中执行它以安装更新版本的 nodejs。这是该脚本的副本：

#!/bin/bash

hash_file="/tmp/nodejshash"

check_if_npm_packages_has_to_be_installed () 
    if [ -f $hash_file ]; then
        check_if_same_hash
    else
        return 0
    fi


check_if_same_hash () 
    hash_new="$(md5sum .ebextensions/bin/install-nodejs.sh 2> /dev/null | cut -d ' ' -f 1)"
    hash_current="$(cat "$hash_file" 2> /dev/null | cut -d ' ' -f 1)"

    if [ $hash_new == $hash_current ]; then
        return 1
    else
        return 0
    fi


install_node () 
    if hash nodejs 2> /dev/null; then
        echo 'nodejs install, add more processing if needed' > /dev/null
    else
        curl -sL https://rpm.nodesource.com/setup_6.x | bash -
        yum install -y nodejs
    fi


install_npm_packages () 
    npm install -g bower
    npm install -g gulp


update_current_hash () 
    echo $hash_new > $hash_file


install_node

if check_if_npm_packages_has_to_be_installed; then
    install_npm_packages
    update_current_hash
fi

2) 如果您默认使用微实例，node-sass 包需要很长时间才能构建并最终超时。我将我的实例大小增加到 t2.small 以解决这个问题。

希望这对其他人有所帮助。

谢谢！ 2 号为我修好了。
