[BUG] Executable doesn't exist at /root/.cache/ms-playwright/chromium-1055/chrome-linux/chrome

[eshk12]

System info

• Playwright Version: latest
• Operating System: Ubuntu

Hello guys, I am trying to run Playwright on a docker container with gui using dorowu/ubuntu-desktop-lxde-vnc image.

I have created this Dockerfile:

FROM dorowu/ubuntu-desktop-lxde-vnc:latest
WORKDIR /tests

RUN apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4EB27DB2A3B88B8B

#Install Node.js & npm
RUN apt-get update
RUN apt-get install -y curl
RUN curl -sL https://deb.nodesource.com/setup_16.x | bash -
RUN apt-get install -y nodejs

COPY . .

# Install Playwright dependencies
RUN npm install
# Install browsers
RUN npx playwright install
# Install test
RUN npx @playwright/test install

When I am running this docker container I am giving a volume that is already holding Playwright installation and if I try to run it from the parent machine it's running.

But when I am running it from the container itself I am getting this error:

browserType.launch: Executable doesn't exist at /root/.cache/ms-playwright/chromium-1055/chrome-linux/chrome

And it's asking me to re-run npx playwright install and I have already run this command on the Dockerfile.

What am I missing here? how can I solve it?

You don't need RUN npx @playwright/test install but thats most likely not the cause of this error. npx playwright is installing the browsers already.

Maybe you have multiple Playwright versions inside your package.json - could you share it with us? It should contain only @playwright/test.

[eshk12]

Hello, Thanks for yours quick response.

Here is the package.json:

{
  "devDependencies": {
    "@playwright/test": "^1.29.2"
  }
}

I've also tried to run the image build without RUN npx @playwright/test install and the results remain the same

[mxschmitt]

So it looks like the npx playwright install is not installing the browsers you want. you could try npx playwright --version to see which version it has. Does it print something at all?

[eshk12]

Yes there is output from this line:

Version 1.32.3

My Node.js version is: V16.19.1
My NPM version is: 8.19.3

[mxschmitt]

This looks good, but is there output from this line?

npx playwright install

You can also set the DEBUG=pw:install env var, which should yield to more output.

Hey, I am getting:

Failed to install browsers
Error: EACCES: permission denied, mkdir '/root/.cache/ms-playwright'

I am using root user.

EDIT:
I've researched and added ENV PLAYWRIGHT_BROWSERS_PATH 0 to the Dockerfile before the Playwright installation section.
now when I am running npx playwright install the installation is started successfully.

I've also tried to run the test again but it failed with the same issue(after the docker installation, not in the manual installation).

There are the logs from npx playwright install:

[mxschmitt]

Does it mean its working now after you set the env var?

It seems like the Docker image messes a bit around with Linux user accounts. It has some special user called ubuntu. And root's home directory is /home/ubuntu which seems against any Linux best practise.

[eshk12]

Thanks @mxschmitt, indeed, when I changed the user to ubuntu its worked.
