- Failing command/step:
  - RUN npm install -g yarn@1.22.22 (Dockerfile:6, builder 2/7)

- Exact error message and exit code:
  - did not complete successfully: exit code: 1
  - npm error EEXIST: file already exists
  - File exists: /usr/local/bin/yarn
  - Remove the existing file and try again, or run npm
  - with --force to overwrite files recklessly.
  - A complete log of this run can be found in: /root/.npm/_logs/2026-03-17T12_24_32_684Z-debug-0.log

- Context / missing packages or files mentioned:
  - The issue is caused by an existing /usr/local/bin/yarn, not a missing package/file.
  - No missing dependencies are reported; the conflict is due to yarn already exists at the target path.

- Version/mismatch information:
  - npm notice: New patch version of npm available! 11.11.0 -> 11.11.1
  - Installing yarn@1.22.22 via npm, conflicting with an existing yarn binary.

Summary (under 1500 chars):

- Failing step (command): [builder 6/9] RUN yarn add react@19.2.3 react-dom@19.2.3

- Exact error message and exit code:
  - error Running this command will add the dependency to the workspace root rather than the workspace itself, which might not be what you want - if you really meant it, make it explicit by running this command again with the -W flag (or --ignore-workspace-root-check).
  - ERROR: process "/bin/sh -c yarn add react@19.2.3 react-dom@19.2.3" did not complete successfully: exit code: 1

- Missing packages or files mentioned: None. The failure is due to Yarn workspace-root check, not a missing file or package.

- Version mismatch info: Yarn version shown: v1.22.22 (yarn add v1.22.22). Base image is node:18-slim; no explicit version mismatch cited.

  - Warning: Resolution field "jsdom@22.1.0" is incompatible with requested version "jsdom@^20.0.0" (version mismatch)
- Context: The failure occurs during dependency installation (yarn install) while building the monorepo, caused by a missing script file referenced by the build.

  - Node.js v18.20.8

  - Docker/Yarn exit: exit code 1 (the command failed with exit code 1)

- Missing packages or files mentioned:

- Version mismatch / warnings observed:
  - warning Resolution field "jsdom@22.1.0" is incompatible with requested version "jsdom@^20.0.0"
  - warning "eslint-plugin-ft-flow@2.0.3" has unmet peer dependency "@babel/eslint-parser@^7.12.0"

  - warning "eslint-plugin-react@6.10.3" has incorrect peer dependency "eslint@^2.0.0 || ^3.0.0"

- Additional context:
  - Yarn install started as part of the builder step; Node.js version shown as v18.20.8
  - No further successful steps or download progress to summarize.

- Purpose: Generate per-renderer Flow configuration files (.flowconfig) for multiple renderers using the inlined host configs and available forks.

- Dependencies/inputs:
  - Node modules: chalk, fs, path, mkdirp
  - Data: ../shared/inlinedHostConfigs
  - flow version: package.json devDependencies['flow-bin']
  - Template: __dirname + '/config/flowconfig'
  - Forks source: packages/forks

- Core data structures:
  - allForks: Set of discovered fork paths (e.g., forks/xxx.js)
  - forkedFiles: Map[file] -> basePath (parent directory containing forks)

- Key functions:
  - findForks(file): discovers forks for a given file, records base path.
  - addFork(forks, renderer, file): maps a forked source to a base fork target; uses existing forks or throws if none found.
  - writeConfig(renderer, rendererInfo, isServerSupported, isFlightSupported):
    - Creates folder: <scriptDir>/<renderer>
    - Determines server/flight renderers (fallback to 'custom' if not supported)
    - Builds ignoredPaths against other renderers’ paths
    - Builds moduleMappings by mapping fork sources to targets
    - Reads template, injects module mappings, ignores, and Flow version
    - Prepends/appends a disclaimer note
    - Writes to <folder>/.flowconfig only if changed; logs “Wrote a Flow config to <path>”

- Processing flow:
  - For each renderer in inlinedHostConfigs where isFlowTyped is true, call writeConfig with:
    - rendererInfo.shortName
    - isServerSupported, isFlightSupported

- Outputs:
  - Per-renderer folder: <scriptDir>/<renderer> containing .flowconfig
  - Final config references:
    - Fork mappings, e.g. ReactFiberConfig, ReactServerStreamConfig, ReactFizzConfig, ReactFlightServerConfig, ReactFlightClientConfig
    - DevTools feature flag mapping: react-devtools-shared/src/config/DevToolsFeatureFlags.default -> react-devtools-feature-flags
  - Flow version substituted from flow-bin in package.json

- Notes:
  - If new config equals existing, no file write occurs.
  - Generating uses a generated config disclaimer header/footer in the flowconfig.

  - Command: RUN npm i -g yarn@1.22.22
- Missing packages or files mentioned:
  - Issue stems from EEXIST when installing yarn@1.22.22 because /usr/local/bin/yarn already exists

- Overall: Build failed at the specified RUN step due to file conflict when installing yarn (exit code 1).

  - Corepack is typically provided by Node distributions; in this image variant corepack is missing, leading to the “not found” error when attempting to run corepack enable/prepare.

- Suggested remediation
  - Install Corepack manually (e.g., run npm i -g corepack) before using corepack, or switch to a Node image that includes Corepack by default, or skip Corepack and install/config Yarn directly.

Summary of Docker build error

Failing step
- [builder 3/8] RUN npm i -g corepack   && corepack enable   && corepack prepare yarn@1.22.22 --activate

Exact error message and exit code
- EEXIST: file already exists
- File exists: /usr/local/bin/yarnpkg
- Remove the existing file and try again, or run npm with --force to overwrite files recklessly.
- A complete log of this run can be found in: /root/.npm/_logs/2026-03-17T13_35_33_953Z-debug-0.log
- The build failed with exit code: 1
- The overall failure output ends with: "ERROR: failed to build: failed to solve: process \"/bin/sh -c npm i -g corepack   && corepack enable   && corepack prepare yarn@1.22.22 --activate\" did not complete successfully: exit code: 1"

Missing packages or files mentioned
- Existing file collision: /usr/local/bin/yarnpkg (pre-existing) prevents npm from installing/activating yarn via corepack/npm

Version mismatch / related notices
- New patch version of npm available! 11.11.0 -> 11.11.1 (suggests updating npm)
- Post-error notice also includes guidance to update npm to 11.11.1

Additional notes
- The error occurs during the step attempting to install and activate Yarn through corepack (yarn@1.22.22) in the builder stage.
