I have try installation at company network and I have problems with grpc
```python
> 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](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](https://github.com/grpc/grpc-node/issues/922))
```python
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](https://github.com/request/request/issues/3142)
And at Jenkins which have more limited accesses, even request installation not help.
```python
14:42:26 node-pre-gyp WARN Pre-built binaries not installable for grpc@1.24.3 and node@12.16.1 (node-v72 ABI, glibc) (falling back to source compile with node-gyp)

```
Also grpc will be deprecated at 2021 [https://www.npmjs.com/package/grpc](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 🙂
Env in windows laptop and in Jenkins linux node

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?

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

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:
```

However when I run the command “python -m Browser.entry init” the failure occurs when downloading firefox:
```

Am I doing something wrong?

```python
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](http://playwright.azureedge.net)) and that fails.
Check your network and dns resolver settings on that particular machine.

You should user right python version… I used Python 3.8 in this one… when also ex. 3.11 version is installed…
