dependency command failed

Error message

dependency command failed

What it means

During dependency installation, the resolved package-manager command (e.g. `npm install`, `cargo build`) ran but exited with a nonzero status. The CLI surfaces a generic bail because the manager already printed its own diagnostics to the terminal.

Solutions

Rerun the command manually (npm install / cargo build) in project_root to see the full error output
Fix the dependency conflict or missing system dependency reported by the manager
Delete lockfile/node_modules (or Cargo.lock/target) and reinstall if the state is corrupt
Check network/proxy connectivity to the package registry

Example fix

// before
$ flow deps install   # opaque failure

// after
$ npm install          # see real error: ERESOLVE conflict
$ # fix version range in package.json, then
$ flow deps install

Defensive patterns

Strategy: try-catch

Validate before calling

// dry-run the manager first where supported
npm install --dry-run || echo "npm install will fail"
# and ensure lockfile/manifest parse:
npm ls --depth=0 >/dev/null 2>&1 || echo "dependency tree broken"

Try / catch

match deps::run(&opts) {
    Err(e) if e.to_string() == "dependency command failed" => {
        eprintln!("package manager failed; rerun the command manually for full output");
        std::process::exit(1);
    }
    other => other,
}

Prevention

Commit valid lockfiles and avoid hand-editing version ranges
Ensure build toolchain (gcc, python, rustup) exists in CI images
Check registry status / proxy settings before large installs
Run installs with verbose output to capture the manager's real error

When it happens

Trigger: Calling deps install when the underlying command fails: unresolvable dependency versions, network failure during fetch, lockfile conflicts, missing system build tools, or a postinstall script error.

Common situations: npm/cargo registry outage or rate limit; package version conflicts after manual Cargo.toml edits; native module compilation failing (missing gcc/python); offline CI environment.
