[BUG] "npx playwright" in vanilla v1.34.1/v1.33.0 container asks to install [email protected]

[bamarch]

System info

• Playwright Version: v1.34.1, v1.33.0
• Operating System: Ubuntu Jammy
• Browser: All
• Other info: This is a bug that affects the Docker image mcr.microsoft.com/playwright:v1.33.0

Source code

• [x] I provided exact source code that allows reproducing the issue locally.

Steps

• Run this to download the image and get a shell

  docker run -it --rm --ipc=host mcr.microsoft.com/playwright:v1.33.0 /bin/bash
  

• Try a simple playwright command inside the docker container

  npx playwright --version
  

Expected

It prints Version 1.33.0 to stdout

i.e. do what the mcr.microsoft.com/playwright:v1.34.0 container does

Actual

It asks to install [email protected]

Need to install the following packages:
  [email protected]
Ok to proceed? (y)

Updated because this bug also affects the v1.34.1 container

docker run -it --rm --ipc=host mcr.microsoft.com/playwright:v1.34.1 /bin/bash

Pinning to 1.34.0 seems to be a workaround

@bamarch This is actually how it's supposed to work. Playwright's docker images do not have Playwright package pre-installed. Usually, you would checkout your project inside, and playwright will be installed as a part of npm install command. Then npx playwright --version and other commands will start working.

However, in the docker image v1.34.0 there was a bug, where playwright accidentally got into npx cache folder, and so npx playwright --version unexpectedly worked. Sorry for confusion!
