我正在尝试部署我的应用程序，但始终无法在IBM cloud CI / CD上运行。我的问题是总是找不到某些模块。找不到的模块列表（安装前一个模块时，每次出现一次）如下：
等...
这继续进行，但我没有继续安装更多丢失的npm软件包。

[当我尝试使用控制台（如git push）通过ibm工具链推送完全相同的项目时，它说无法部署该应用程序，并且在检查日志时发现模块未找到错误。这是日志的副本：

[当我尝试使用ibmcloud登录进行推送时，将--cf和cf push作为目标，则该应用程序已成功推送。我不确定错误来自何处，因为我想继续通过工具链使用git push命令进行部署。
请参见manifest.yml文件以下：
applications:
- buildpacks: ['sdk-for-nodejs']
command: npm prune --production && NODE_ENV=production npm start
domain: null
env:
NPM_CONFIG_PRODUCTION: false
NODE_MODULES_CACHE: false
host: null
instances: 1
memory: 256M
name: mern_1
timeout: 360
domain: null
host: null
我还尝试安装具有相同项目配置的新工具链，但同样失败。
谁能帮我解决这个问题？
感谢ibm开发人员发现了一个不错的解决方案，方法是删除manifest.yml上的npm prune --production &&并将其添加到postintall脚本的package.json中。就我而言，它解决了我的问题。能够成功推送。
