Python - Google Colab - Instalando o Brave

		Python- Google Colab - Instalando o Brave
Canal Qb

O Brave é um navegador da web que é baseado no mesmo mecanismo do Google Chrome, o que significa que muitos dos drivers e bibliotecas que funcionam com o Chrome também funcionam com o Brave. No entanto, o Brave não está disponível diretamente no Google Colab e não pode ser instalado usando o gerenciador de pacotes padrão do Colab.

Se você precisar usar o Brave em seu código Python no Colab, uma opção é instalar o pacote brave-browser, que permite controlar o navegador Brave usando o Selenium. Para instalar o pacote, execute o seguinte comando: 

!pip install brave-browser

Em seguida, você pode usar o driver do Selenium para o Chrome com o executável do Brave. O caminho para o executável do Brave no Colab é /usr/bin/brave-browser, portanto, você pode definir o caminho para o executável do Brave no parâmetro binary_location do driver do Selenium, como no exemplo a seguir: 

from selenium import webdriver

options = webdriver.ChromeOptions()

options.binary_location = '/usr/bin/brave-browser'

driver = webdriver.Chrome(options=options)

Com esse código, você deve ser capaz de controlar o Brave usando o driver do Selenium.

!pip install chromedriver-binary

--*--

Esse erro ocorre porque o pacote brave-browser não está disponível no repositório padrão do Python (PyPI). Uma possível solução é instalar o Brave manualmente no Colab. Para fazer isso, siga os seguintes passos:

Instale o pacote curl para baixar o instalador do Brave: 

!apt install curl

Baixe o instalador do Brave: 

!curl -s https://brave-browser-apt-release.s3.brave.com/brave-core.asc | sudo apt-key --keyring /etc/apt/trusted.gpg.d/brave-browser-release.gpg add -

!echo "deb [arch=amd64] https://brave-browser-apt-release.s3.brave.com/ stable main" | sudo tee /etc/apt/sources.list.d/brave-browser-release.list

!sudo apt update

!sudo apt install brave-browser

Importe o pacote webdriver do Selenium e configure as opções do Brave: 

from selenium import webdriver

from selenium.webdriver.chrome.service import Service

options = webdriver.ChromeOptions()

options.binary_location = '/usr/bin/brave-browser'

Crie uma instância do driver do Selenium para o Brave: 

service = Service('/usr/lib/chromium-browser/chromedriver')

browser = webdriver.Chrome(service=service, options=options)

Com esses passos, você deve ser capaz de usar o Brave no Colab. Lembre-se de que o caminho do driver do Chrome (chromedriver) pode ser diferente no seu sistema, dependendo da versão do Brave que você instalou. Verifique se o caminho está correto antes de criar uma instância do driver.

!curl -sSL https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

!echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" | sudo tee /etc/apt/sources.list.d/google-chrome.list

!sudo apt-get update

!sudo apt-get install google-chrome-stable

!sudo apt-get install chromedriver

!apt-get update

!apt-get install -y chromium-browser

!apt-get install -yqq unzip

!curl -sSL https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb -o /tmp/chrome.deb

!dpkg -i /tmp/chrome.deb

!apt-get install -yqq --no-install-recommends python3-selenium

!apt-get install -y chromium-chromedriver
