OpenShift pod 中的'npm ERR! could not determine executable to run'

Question

我正在尝试部署一个Angular应用程序到OpenShift，下面是我的package.json的副本

{
"name": "app-admin",
"version": "0.1.0",
"scripts": {
"global": "npm install",
"start": "npx ng serve",
"build": "npx ng build",
"watch": "npx ng build --watch --configuration development",
"test": "npx ng test",
"e2e": "npx ng e2e",
"cypress:open": "cypress open",
"cypress:run": "cypress run"
},
"private": true,
"dependencies": {
"@angular/animations": "^14.2.0",
"@angular/common": "^14.2.0",
"@angular/compiler": "^14.2.0",
"@angular/core": "^14.2.0",

"npm": "^9.2.0",

},
"devDependencies": {

"@angular/compiler-cli": "^14.2.0",
"@cypress/schematic": "^2.2.0",

"typescript": "~4.7.2"
},
"overrides": {  
"loader-utils@>2.0.0 <3": "2.0.4",
"loader-utils@>3.0.0 <4": "3.2.1"
}
}

pod在npx ng serve失败，出现以下错误

ERROR: ld.so: object 'libnss_wrapper.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

npm ERR! could not determine executable to run

我已经尝试了这个链接中的每个答案，并阅读了这个reddit帖子。来自其他stackoverflow帖子的解决方案在调试pod中工作，但当我在scripts中添加步骤时。在下次构建中，pods再次出现相同的错误。

我尝试添加到scripts的东西:

"install": "npm install -g npm@9.2.0"
"prestart": "npm install -g"

还尝试将npm版本放在dependencies中，并使用engines指定npm版本。

任何帮助都是感激的。

您可能没有将glibc或nss_wrapper-libs包放入容器中。有些npm模块需要它在安装过程中执行编译(比如couchbase模块)。

您可以尝试使用多阶段构建dockerfile，并且只在构建器映像中使用glibc，而不是最终映像。

在我的例子中，出现这个问题是因为没有安装package.json中的devdependencies。我必须通过一个环境变量NODE_DEV=development来安装它们，这解决了我的问题。感谢这篇文章。
