Express.js For CircleCI

Build Environment
1

Hi guys I am trying to set up CircleCI for a Express.js project. When I used the default config file.

# Javascript Node CircleCI 2.0 configuration file
#
# Check https://circleci.com/docs/2.0/language-javascript/ for more details
#
version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      - image: circleci/node:7.10

      # Specify service dependencies here if necessary
      # CircleCI maintains a library of pre-built images
      # documented at https://circleci.com/docs/2.0/circleci-images/
      # - image: circleci/mongo:3.4.4

    working_directory: ~/repo

    steps:
      - checkout

      # Download and cache dependencies
      - restore_cache:
          keys:
          - v1-dependencies-{{ checksum "package.json" }}
          # fallback to using the latest cache if no exact match is found
          - v1-dependencies-

      - run: yarn install

      - save_cache:
          paths:
            - node_modules
          key: v1-dependencies-{{ checksum "package.json" }}

      # run tests!
      - run: yarn test

However when I try building this project I get some cache errors.

Error computing cache key: template: cacheKey:1:19: executing "cacheKey" at <checksum "package.js...>: error calling checksum: open /home/circleci/repo/package.json: no such file or directory

Error computing cache key: template: cacheKey:1:19: executing "cacheKey" at <checksum "package.js...>: error calling checksum: open /home/circleci/repo/package.json: no such file or directory

Finally I get this error.

#!/bin/bash -eo pipefail
yarn test
yarn test v0.24.4
error Couldn't find a package.json file in "/home/circleci/repo"
Exited with code 1

In the config file when I change the working directory it doesn’t seem to make a difference.

I’d assume that ~/repo/package.json does not exist. After your checkout step, try adding

- run: ls -l ~/repo

to see if the file is indeed part of your repo. Maybe it’s not committed?
