Exit code: 1

Command that failed
- npm run build

Missing packages or files mentioned
- Missing module: '/app/build' (the build script attempts to run node build, but the file/module at /app/build cannot be found)

Version/mismatch information
- Base image: node:18-slim
- Node.js version during run: v18.20.8

Additional context from the step
- The log shows the build script executes: dayjs@0.0.0-development build -> cross-env BABEL_ENV=build node build && npm run size, which relies on a file at /app/build that is not present.

Failing step:

-   requireStack: []
- }
- Node.js v18.20.8
- Exit code: 1

Context and missing/files:
- The RUN command executes: npm run babel, which runs "babel src --out-dir esm --copy-files && node build/esm".
- Babel outputs to the esm directory, but the error indicates a missing '/app/build/esm', i.e., a mismatch where the runtime expects build/esm, which was not created.

Version info:
- Node.js version reported: v18.20.8
- Base image: node:18-slim
- The failure occurs after Babel reports successful compilation, suggesting a path/output mismatch rather than a syntax error.

  process "/bin/sh -c npm run babel" did not complete successfully: exit code: 1

- Missing files / path issues:
  - The failure is due to Cannot find module '/app/build/esm'.
  - Babel was configured to output to esm (out-dir esm), but the subsequent node run tries to execute build/esm, indicating a path mismatch between Babel output (./esm) and the file it attempts to run (./build/esm).

- Version/mismatch info:
  - Node.js version shown: v18.20.8
  - Base image used: node:18-slim
  - The script sequence in the Dockerfile runs: babel outputs to esm, then tries to run node build/esm, which mismatches the expected output location.

  - Base image uses Node.js 18 (node:18-slim), which conflicts with many packages that require Node >= 20
  - Note: npm itself indicates a new major version available (10.8.2 -> 11.12.0), but the primary issue is engine incompatibility with Node 18.

  - Stage [stage-1 4/4]: COPY --from=builder /app/node_modules ./node_modules 2>/dev/null || true

- Missing packages or files mentioned
  - No explicit missing package/file names. The failure is caused by invalid shell redirection in the COPY instructions (2>/dev/null || true) being treated as part of the reference during checksum calculation.

  - Warning: FromAsCasing: 'as' and 'FROM' keywords' casing do not match (line 2)
  - Base image used: node:20-slim (as seen in the build steps)

- Additional context
  - Root cause appears to be the invalid use of shell redirection (2>/dev/null || true) in COPY commands, which Docker cannot checksum correctly. Proposed fix: remove the redirection and keep straightforward COPY commands:

- Missing files/build artifact: dayjs.min.js or dist/dayjs.min.js (No build artifact found)
- Earlier steps related: Step 10 printed "No build script detected, skipping build"; Step 11 printed "No build artifact found" before the final failure
- Warning observed: FromAsCasing: 'as' and 'FROM' keywords' casing do not match (line 2)

Concise summary of the tool output (preserving actionable items):

- Library: Dayjs-like date library (export default dayjs), with a Dayjs class and plugin system.

- Imports (file paths):
  - import * as C from './constant'
  - import en from './locale/en'
  - import U from './utils'

- Locale handling:
  - Global locale: L = 'en'
  - Global loaded locales: Ls = { en: en }
  - parseLocale(preset, object, isLocal) to resolve and load locales
  - dayjs.locale = parseLocale
  - dayjs.en = Ls[L], dayjs.Ls = Ls

- Core helpers:
  - isDayjs detection via IS_DAYJS and Dayjs prototype
  - dayjs factory function: creates Dayjs instances; clones if input is a Dayjs
  - wrapper(date, instance) to wrap date with locale/utc/x and offset
  - Utils alias for U; Utils.l = parseLocale; Utils.i = isDayjs; Utils.w = wrapper

- Date parsing:
  - parseDate(cfg): handles null (NaN), today, Date, and string parsing via C.REGEX_PARSE
  - Special handling for utc flag

- Dayjs class (core API):
  - Constructor(cfg): sets locale, parses cfg, initializes fields
  - parse(cfg), init(): populate date parts ($y, $M, $D, $W, $H, $m, $s, $ms)
  - Localization: $locale(), locale(preset, object)
  - Cloning/toDate/toJSON/toISOString/toString
  - Validation: isValid
  - Comparisons: isSame(that, units), isAfter(that, units), isBefore(that, units)
  - Getters/setters: get(unit), set(string, int), $g(input, get, set)
  - Arithmetic: add(number, units), subtract(number, units)
  - Formatting: format(formatStr) with tokens (YY, YYYY, M, MM, MMM, MMMM, D, DD, d, dd, ddd, dddd, H, HH, h, hh, a, A, m, mm, s, ss, SSS, Z)
  - Start/end: startOf(units, startOf), endOf(arg)
  - Duration/offset: utcOffset(), diff(input, units, float)
  - Date math helpers: daysInMonth()
  - Internal locale access: $locale()
  - Utility: days/weeks/months calculation, locale-aware formatting

- Internal token mapping (compat): maps internal codes to public units (e.g., $ms, $s, $m, $H, $W, $M, $y, $D)

- Plugins:
  - dayjs.extend(plugin, option): installs a plugin once
  - Returns the dayjs function to allow chaining

- Utilities on Dayjs namespace:
  - dayjs.unix(timestamp)
  - dayjs.isDayjs
  - dayjs.en, dayjs.Ls, dayjs.p

- Export:
  - export default dayjs

Notes:
- The code relies on a constant module (C) for unit tokens, a locale file (locale/en), and a utils module (U).
- The library exposes a locale-aware, plugin-extensible date API with formatting tokens, relative time arithmetic, and ISO/string conversions.
