Problem

Current Behavior: I have been using `npx <some-workflow-helper>` over the past year to run the current version of a command without having to manage updating it. npm7 does not pull the latest version if I have run it once before... i suspect because its no longer a temp install... Expected Behavior: `npx some-package` always runs the latest published version. Steps To Reproduce: 1. `npx <test-package>` 2. publish a new version of <test-package> 3. `npx <test-package>` Environment: - OS: Fedora 33 - Node: 14.15.0 - npm: 7.1.0

Force npx to Fetch Latest Package Version

Medium Risk

The issue arises because npx caches the last used version of a package, preventing it from fetching the latest version on subsequent runs. This behavior is due to npm's design where it prioritizes efficiency by avoiding repeated downloads of the same package unless explicitly instructed to do so.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Clear npx cache

    Clear the npx cache to ensure that the next invocation fetches the latest version of the package.

    bash
    npx cache clear
  2. 2

    Use npx with the latest flag

    Run npx with the --latest flag to explicitly request the latest version of the package.

    bash
    npx --latest <test-package>
  3. 3

    Update npm to the latest version

    Ensure that you are using the latest version of npm, as newer versions may have bug fixes or improvements related to npx and package fetching.

    bash
    npm install -g npm@latest
  4. 4

    Check for global installations

    Verify if the package is installed globally, as this may affect the version npx uses. If it is, consider uninstalling the global version.

    bash
    npm uninstall -g <test-package>
  5. 5

    Test the package after changes

    After performing the above steps, run the package again to confirm that the latest version is being fetched and executed.

    bash
    npx <test-package>

Validation

To confirm the fix worked, run 'npx <test-package>' and check if the output reflects the latest version published. You can also verify the version by checking the package's release notes or changelog.
