[BUG] npx --force warning hides confirmation prompt to install package

[bmwalters]

Current Behavior

When using npx --force, the warning printed due to using --force covers up the prompt asking the user to enter "y" to proceed. At first glance it looks like the command has hung waiting for I/O or something.

$ npx --force mkdirp
npm WARN using --force Recommended protections disabled.
Need to install the following packages:
  mkdirp
⸨░░░░░░░░░░░░░░░░░░⸩ ⠙ : WARN using --force Recommended protections disabled.

Expected Behavior

The command output should not hide the line prompting the user to enter "y" to proceed.

Steps To Reproduce

1. Use a system without any packages installed globally / in the cache.
2. npx --force mkdirp.
3. Observe the command output.

Environment

• OS: macOS 11.3.1
• Node: 16.3.0
• npm: 7.15.1
• shell: fish 3.2.2

This does not attempt to pause the log, if log.clearProgress() is available:

This also happens when trying npm cache clean --force

I've post PR npm/libnpmexec#8 to fix this issue.

@lauta3011 npm cache clean --force works for me as it is supposed, and also npm cache clean. Could you provide more details about what happened to you?

With new libnpmexec:

~/D/n/cli (release-next↑1|✔) $ node . exec @gar/create-test --force
npm WARN using --force Recommended protections disabled.
Need to install the following packages:
  @gar/create-test
Ok to proceed? (y)
