node.js - 将 node.js 应用程序部署到 Amazon Elastic beanstalk 时出错

Question

我最近在 beantalk 上部署了一个新的 node.js 应用程序并一直遇到以下错误？

[实例:i-cce89e4a] 命令在实例上失败。返回代码:1 输出:(TRUNCATED)...opt/elasticbeanstalk/containerfiles/ebnode.py"，第 180 行，在 npm_install raise e subprocess.CalledProcessError: Command '['/opt/elasticbeanstalk/node-install/node-v4 .4.6-linux-x64/bin/npm', '--production', 'rebuild']' 返回非零退出状态 254。 Hook /opt/elasticbeanstalk/hooks/configdeploy/pre/50npm.sh 失败。更多详细信息，请使用控制台或 EB CLI 检查/var/log/eb-activity.log。

我的node版本是:4.4.7

部署似乎在下面的最后一行失败:

 except Exception, e:
            npm_debug_log = '/var/log/nodejs/npm-debug.log'
            app_npm_debug_log = os.path.join(app_path, "npm-debug.log")
            write_event('Failed to run npm install. Snapshot logs for more details.', 'ERROR')
            if not os.path.exists(app_npm_debug_log):
                utc_time_str = datetime.datetime.utcnow().strftime("UTC %Y/%m/%d %H:%M:%S")
                err_msg = str.format("{0} cannot find application npm debug log at {1} \n", utc_time_str, app_npm_debug_log)
                print(err_msg)
                with open(npm_debug_log, 'a') as f:
                    f.write(err_msg)
            else:
                shutil.copyfile(app_npm_debug_log, npm_debug_log)
            raise e

我似乎找不到任何可靠的解决方案？

我手动压缩并上传了文件。

该应用程序在本地完美运行。

有人能帮忙吗？

Answer 1

我没有足够的信息来回答... /var/log/eb-activity.log 说什么？

...但是 在带有 t2.small 的 beantalk 上运行 npm install 时，我遇到了类似的错误:它没有足够的 RAM，npm 失败。升级到更大的实例可以解决问题。 (提交 node_module 也可以解决这个问题，但我不想)。

您应该做的是使用 SSH 连接到实例，并使用 top/htop 观察部署时发生的情况。
