Problems with rfbrowser init

I have try installation at company network and I have problems with grpc

> grpc@1.24.3 install c:\users\xxxx\py37\venv\lib\site-packages\Browser\wrapper\node_modules\grpc

> node-pre-gyp install --fallback-to-build --library=static_library

 

node-pre-gyp WARN Using needle for node-pre-gyp https download

node-pre-gyp WARN Tried to download(400): https://node-precompiled-binaries.grpc.io/grpc/v1.24.3/node-v72-win32-x64-unknown.tar.gz

node-pre-gyp WARN Pre-built binaries not found for grpc@1.24.3 and node@12.13.0 (node-v72 ABI, unknown) (falling back to source compile with node-gyp)

There is a way to download binaries from other url using --grpc_node_binary_host_mirror, but looks like it only affects to node-v72-win32-x64-unknown.tar.gz and then https://node-precompiled-binaries.grpc.io/grpc-tools/v1.9.1/win32-x64.tar.gz download will still failing

Work around for this problem is to install request (https://github.com/grpc/grpc-node/issues/922)

pip install robotframework-browser
cd venv\Lib\site-packages\Browser\wrapper
npm install request
npm install --production

But request has been deprecated, see https://github.com/request/request/issues/3142

And at Jenkins which have more limited accesses, even request installation not help.

Also grpc will be deprecated at 2021 https://www.npmjs.com/package/grpc

Any tips for pre-built binaries issue? I’m not familiar with node.js, so all tips are welcome :slight_smile:

Env in windows laptop and in Jenkins linux node

  • python: 3.7.x
  • node: 12.x
  • npm: 6.x

Please retry installation with the Browser 2.0 release. We have changed the library dependencies and this should not be a problem anymore.

No more grpc problems, but still not working. Any workaround for this?

12:57:17  rfbrowser init completed

That seems like an error with your Internet. Playwright keeps the browser binaries in a custom location and it’s possible that your vpn/firewall/antivirus software doesn’t allow connection.

You could try to disable example each of the above programs one by one and see does it help.

I just downloaded the library as mentionned in the installation instructions with pip install robotframework-browser.

When i run rfbrowser init, it says that it can`t find any module named Browser.

Any ideas why this is happening ?

Thanks for any help

Make sure that you have the recommended versions of python and nodejs
See version requirements here:
MarketSquare/robotframework-browser: Robot Framework Browser library powered by Playwright. (github.com)

Hi anton264,

I have Python 3.8 as well as node.js version 12.16.2.

I think those are OK.

I was wondering if the rfbrowser init command needs to be run with an elevated command prompt ?

Thanks

Can anyone help me with the following situation?
When I run the command “rfbrowser init”, the chromium download fails:

Am I doing something wrong?

Error: getaddrinfo ENOTFOUND

Your connectivity on the machine you are trying to init is failing. ENOTFOUND indicates that the the machine is trying to query IP address of the host (in this case, playwright.azureedge.net) and that fails.

Check your network and dns resolver settings on that particular machine.
