npm全球安装在弹性豆茎上

Question

我在aws弹性豆茎上全局安装pm2时遇到问题。我创建了以下用于安装pm2的脚本：

option_settings:
  - option_name: NODE_ENV
    value: production
container_commands:
  01_enable_rootaccess:
    command: echo Defaults:root !requiretty >> /etc/sudoers 
  02_install_imagemagic:
    command: yum install -y ImageMagick
  03_download_new_relic:
    command: rpm -Uvh http://download.newrelic.com/pub/newrelic/el5/i386/newrelic-repo-5-3.noarch.rpm 
    ignoreErrors: true
  04_install_new_relic:
    command: yum install -y newrelic-sysmond
    ignoreErrors: true
  05_add_license_key:
    command: /usr/sbin/nrsysmond-config --set license_key=xxxxxxx
    ignoreErrors: true
  06_start_new_relic:
    command: /etc/init.d/newrelic-sysmond start
    ignoreErrors: true
  07_install_pm2:
    command: sudo /opt/elasticbeanstalk/node-install/node-v0.10.26-linux-x64/bin/npm install pm2 -g
    ignoreErrors: true    
  08_stop_old_pm2_processes:
    command: sudo /opt/elasticbeanstalk/node-install/node-v0.10.26-linux-x64/bin/pm2 delete all
    ignoreErrors: true
  09_start_pm2:
    command: sudo /opt/elasticbeanstalk/node-install/node-v0.10.26-linux-x64/bin/pm2 startup -u ec2-user
    ignoreErrors: true

我试过只对命令8&9把我只是得到命令没有找到。当我给出pm2的特定路径时(我登录到ec2并验证(，我得到"行4:exec:：未找到"。你知道我在这里做错了什么吗？提前感谢您的帮助！

我成功地在弹性豆茎上全局安装了pm2，并在.eextensions/your_file_name.config文件中嵌入了以下代码片段

container_commands:
  01_node_symlink:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/node /bin/node"
  02_npm_symlink:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/npm /bin/npm"
  03_pm2_install:
    command: "if [ ! -e /bin/pm2 ]; then npm install pm2 -g; fi"
    ignoreErrors: true

您可能需要确保安装了nodejs-legacy模块。如果pm2依赖于名为node的可执行文件，那么当系统将其全局安装为nodejs时，这将失败，就像一些Linux系统(Ubuntu、Debian(经常做的那样。
