Elasticbeanstalk扩展找不到NPM

Question

我遇到了ebextension配置文件并出现了问题，尽管从服务器终端运行npm命令时我仍然能够访问npm，但我的服务器却找不到npm。这可能与配置文件尝试查找npm的位置有关吗？下面提供了错误和我的ebextension配置文件。

Running 4 of 5 actions: EbExtensionPostBuild...
Command execution failed: Activity failed. (ElasticBeanstalk::ActivityFatalError)
    caused by: /bin/sh: npm: command not found
{"status":"FAILURE","api_version":"1.0","results":[{"status":"FAILURE","msg":"/bin/sh: npm: command not found. \ncontainer_command 01_webpack_build in .ebextensions/01_npm_build_start.config failed.

01_npm_build_start.config ：

container_commands:
    01_webpack_build:
        command: "npm run build"
    02_run_node:
        command: "npm start"

package.json：

  "scripts": {
    "start": "node app.js",
    "build": "webpack",
}
