node.js - 在Docker容器中找不到依赖项

Question

我正在尝试在Docker容器中为我的节点项目设置测试环境。我正在使用以下Dockerfile:

FROM node:14.4.0-alpine

RUN npm install -g ava

USER node
WORKDIR /home/node
COPY --chown=node package*.json ./
RUN npm install
ENV PATH=/home/node/node_modules/.bin:$PATH

WORKDIR /test

CMD [ "npm", "test" ]

我正在使用以下命令运行容器:

docker run -v `pwd`:/test -t <name>

现在，我收到此错误:

> goFit@1.0.0 test /test
> ava

(node:24) UnhandledPromiseRejectionWarning: Error: Could not resolve required module ’esm’

(node:24) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:24) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

如果我使用以下命令设置 NODE_PATH环境变量:

ENV NODE_PATH=/home/node/node_modules

然后错误更改为:

  Uncaught exception in tests/workout_factory.test.js

  Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'ava' imported from /test/tests/workout_factory.test.js
  Did you mean to import ava/index.js?

  › Did you mean to import ava/index.js?

  › ModuleWrap.<anonymous> (internal/modules/esm/module_job.js:50:40)
  › link (internal/modules/esm/module_job.js:49:36)

如果有帮助，我正在使用以下 package.json:

{
  "name": "goFit",
  "version": "1.0.0",
  "description": "api web para entrenamiento personal",
  "main": "index.js",
  "directories": {
    "doc": "docs"
  },
  "type": "module",
  "scripts": {
    "test": "ava"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/ElenaMerelo/goFit.git"
  },
  "keywords": [
    "workout",
    "fitness",
    "fit"
  ],
  "author": "Elena Merelo Molina",
  "license": "GPL-3.0",
  "bugs": {
    "url": "https://github.com/ElenaMerelo/goFit/issues"
  },
  "homepage": "https://github.com/ElenaMerelo/goFit#readme",
  "devDependencies": {
    "ava": "^3.13.0",
    "esm": "^3.2.25"
  },
  "ava": {
    "files": [
      "tests/**/*",
      "!tests/exercises_data.js"
    ],
    "cache": false,
    "require": [
      "esm"
    ]
  },
  "dependencies": {}
}

有谁知道为什么不起作用？

Dockerfile有几处错误:

您需要全局安装所有dev依赖项。他们需要对所有用户可用

您需要使用文件系统顶部的权限来设置/node_modules目录。这不是一件好事，但它与/test处于同一级别，它将停止寻找。这使得Dockerfile保持这种形状

RUN npm install -g ava esm && mkdir /node_modules && chown node /node_modules && chmod 755 /node_modules

USER node
COPY --chown=node package*.json ./
RUN npm install
ENV PATH=/home/node/node_modules/.bin:$PATH

WORKDIR /test

CMD [ "npm", "test" ]

还请记住

在生产环境中使用npm ci。 npm我仅应用于安装单个软件包。

仍然可能不需要

PATH设置。

完成后，将package*json删除为root。
