[bug\_fix] ERR\_PNPM\_NO\_REMOTE\_MIRROR: No mirror found for package tarball

Set a valid npm registry mirror using \`--registry\` or configure \`pnpm config set registry \`. Alternatively, download the package directly from npm's official registry \(if you are using a mirror that is down\).

Journey Context:
I was using pnpm to install dependencies in an offline‑friendly CI environment that had an internal registry mirror. The error 'No mirror found for package tarball' appeared because pnpm could not reach the configured registry \(which was an incomplete or broken mirror\). The fix was to switch to the official npm registry by adding \`--registry https://registry.npmjs.org\` to the install command, or configure \`pnpm config set registry https://registry.npmjs.org\`. The root cause is that pnpm uses the registry configured in \`.npmrc\` or pnpm config; if that mirror is missing some packages, pnpm falls back but only if a remote mirror is available. The error means no valid mirror was found for that specific package tarball. The fix ensures a complete and accessible registry.
