Fix DeepSeek Harness Update Failure & DSH plugin Rollback

If a DeepSeek Harness update fails, check how you installed first: npx errors are usually network or npm cache problems, source builds mostly hit git pull conflicts. Roll back to the old version when needed, and reinstall failed DSH plugins from DSH Plugin Hub.

Overview

An update failure is not a single problem — first find out which install method you used. DSH is in developer preview (currently 0.1.0-rc.6) and iterates fast (source). The npx one-liner and the source build update along completely different paths and fail with completely different errors — npx pulls the latest package from npm on every launch, while a source build fetches code via git pull and compiles locally. The first step is to identify your install method, then fix accordingly; otherwise you may chase a network issue as if it were a code problem.

How do you tell which one you are? If you start DSH with npx @deepseek-ai/dsh web, you are on the npx path. If you cloned the deepseek-harness repository, built it, and update with git pull, you are on the source path. The two failure modes below are covered separately — find yours.

Why a DeepSeek Harness update failed: npx errors and git pull conflicts

With npx, nine times out of ten the failure is network or npm cache. npx @deepseek-ai/dsh web pulls the latest package from npm on every launch (source), and that fetch fails in three typical ways:

1. The network is down or the npm registry is slow, shown as timeouts / ETIMEDOUT / ECONNRESET. First confirm the registry in use: npm config get registry (default https://registry.npmjs.org/), then switch to a mirror with npm config set registry https://registry.npmmirror.com and retry. If it still times out, check the proxy: npm config get proxy, and make sure it is valid and not pointing the registry to an unreachable address.
2. The npm cache is corrupted, with EINTEGRITY / EACCES errors. Run npm cache clean --force and retry. If EACCES keeps coming back, the npm global directory lacks write permission — check the location with npm config get prefix and fix the ownership (e.g. sudo chown -R $(whoami) <prefix>).
3. Node is too old — check with node -v and upgrade to a newer version. An outdated Node often fails while resolving dependencies with syntax-like errors, a hidden trap common in preview projects.

With a source build, the failure is almost always a git pull conflict. When you run git pull with uncommitted local changes, git refuses to merge and reports a conflict. Stash them first with git stash, pull, then git stash pop; or commit your changes before pulling. If conflicts remain after git stash pop, your local edits overlap with upstream — open the conflicting files, merge manually, and git add the resolved files. After resolving, rebuild with pnpm install && pnpm run build (source).

A quick check before pulling: run git status to see whether you have uncommitted changes in the first place — a clean working tree means git pull cannot conflict, and if it still fails, the problem is upstream or the network instead.

How to roll back DeepSeek Harness after a failed update

Rollback also depends on the install method: pin a version with npx, or revert with git for source builds. The goal is to return to the last version that worked, not blindly to the oldest one — the older the version, the worse its compatibility with your current plugins.

• With npx there is no local install, so just run a pinned version: npx @deepseek-ai/[email protected] web (replace the version with the one you want). Not sure which versions exist? List them all with npm view @deepseek-ai/dsh versions.
• With a source build, run git log --oneline to find the commit you want, git checkout <commit> to switch back to the old code, then pnpm install && pnpm run build. To get back to the latest later, git checkout master (or your branch name) and git pull again.

Back up the session data under ~/.dsh/sessions before rolling back, so nothing is lost if things go sideways. After rolling back, start DSH once to confirm the Web UI works, then load your usual plugins one by one to make sure there are no compatibility errors before you rely on it.

What to do when a DSH plugin upgrade fails

When a plugin upgrade errors, first make sure the DSH core is the latest, then check the plugin source. If the core is behind, plugin dependency declarations between preview versions can be incompatible and dsh plugin --profile web update will simply fail. Once the core is confirmed current, a plugin that keeps failing to upgrade usually has a broken package — reinstall it from DSH Plugin Hub, the built-in Settings → Plugin Center. DSH Plugin Hub is the community plugin marketplace with 4,401 human-curated plugins synced daily, and its detail pages declare the compatible DSH version — check it before upgrading.

Another common case is plugins installed from a GitHub source: git-distributed packages may lack version tags or committed build output, so the entry file can be missing after install. For such errors, prefer the npm-published version or report it to the author. To tell the source, check the detail page — it lists npm or github as the install source. For GitHub-sourced plugins, confirm the repository has a matching version tag before upgrading; if it does not, ask the author for a new release.

After any plugin upgrade, restart dsh web and run the feature the plugin provides — an upgrade that reports success but silently breaks a capability is easy to miss in preview builds. When in doubt, verify the installed version with pnpm list in the profile directory and compare it with the one you intended.

Notes

1. DSH is a preview release — back up ~/.dsh/sessions before updating.
2. Don't skip many versions at once; follow the release cadence.
3. Check a plugin's compatible version before upgrading and run your main flows after.
4. If a plugin stops loading after an update, see DSH troubleshooting.
