如何更新Windows 10的chrome驱动程序

Question

您好我想将我的Chrome驱动程序更新到最新版本但是ant找到有关更新驱动程序的任何信息，只需要安装它的信息。如何将驱动程序更新到最新版本需要做什么？

Answer 1

chromedriver是一个单独的可执行文件。只需用新版本替换现有版本即可。

1. 从https://sites.google.com/a/chromium.org/chromedriver/downloads下载最新版本的chromedriver_win32.zip
2. 解压缩文件以解压缩chromedriver.exe
3. 用这个新的可执行文件替换现有文件。

Answer 2

最近我发现chromedriver现在几乎是一对一的版本（chromedriver 2.46有三个最后发布的支持政策）。请参阅版本选择指南：https://sites.google.com/a/chromium.org/chromedriver/downloads/version-selection

我有wrote simple powershell script自动更新chromedriver。

当您需要更新crhomedriver时运行此脚本（我运行此脚本作为我的CI中的构建步骤，就在我运行selenium web测试之前）：

$thisScriptRoot = if ($PSScriptRoot -eq "") { "." } else { $PSScriptRoot }

$chromeDriverRelativeDir = "Selenium"
$chromeDriverDir = $(Join-Path $thisScriptRoot $chromeDriverRelativeDir)
$chromeDriverFileLocation = $(Join-Path $chromeDriverDir "chromedriver.exe")
$chromeVersion = [System.Diagnostics.FileVersionInfo]::GetVersionInfo("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe").FileVersion
$chromeMajorVersion = $chromeVersion.split(".")[0]

if (-Not (Test-Path $chromeDriverDir -PathType Container)) {
  $dir = New-Item -ItemType directory -Path $chromeDriverDir
}

if (Test-Path $chromeDriverFileLocation -PathType Leaf) {
  # get version of curent chromedriver.exe
  $chromeDriverFileVersion = (& $chromeDriverFileLocation --version)
  $chromeDriverFileVersionHasMatch = $chromeDriverFileVersion -match "ChromeDriver (\d+\.\d+\.\d+(\.\d+)?)"
  $chromeDriverCurrentVersion = $matches[1]

  if (-Not $chromeDriverFileVersionHasMatch) {
    Exit
  }
}
else {
  # if chromedriver.exe not found, will download it
  $chromeDriverCurrentVersion = ''
}

if ($chromeMajorVersion -lt 73) {
  # for chrome versions < 73 will use chromedriver v2.46 (which supports chrome v71-73)
  $chromeDriverExpectedVersion = "2.46"
  $chromeDriverVersionUrl = "https://chromedriver.storage.googleapis.com/LATEST_RELEASE"
}
else {
  $chromeDriverExpectedVersion = $chromeVersion.split(".")[0..2] -join "."
  $chromeDriverVersionUrl = "https://chromedriver.storage.googleapis.com/LATEST_RELEASE_" + $chromeDriverExpectedVersion
}

$chromeDriverLatestVersion = Invoke-RestMethod -Uri $chromeDriverVersionUrl

Write-Output "chrome version:       $chromeVersion"
Write-Output "chromedriver version: $chromeDriverCurrentVersion"
Write-Output "chromedriver latest:  $chromeDriverLatestVersion"

# will update chromedriver.exe if MAJOR.MINOR.PATCH
$needUpdateChromeDriver = $chromeDriverCurrentVersion -ne $chromeDriverLatestVersion
if ($needUpdateChromeDriver) {
  $chromeDriverZipLink = "https://chromedriver.storage.googleapis.com/" + $chromeDriverLatestVersion + "/chromedriver_win32.zip"
  Write-Output "Will download $chromeDriverZipLink"

  $chromeDriverZipFileLocation = $(Join-Path $chromeDriverDir "chromedriver_win32.zip")

  Invoke-WebRequest -Uri $chromeDriverZipLink -OutFile $chromeDriverZipFileLocation
  Expand-Archive $chromeDriverZipFileLocation -DestinationPath $(Join-Path $thisScriptRoot $chromeDriverRelativeDir) -Force
  Remove-Item -Path $chromeDriverZipFileLocation -Force
  $chromeDriverFileVersion = (& $chromeDriverFileLocation --version)
  Write-Output "chromedriver updated to version $chromeDriverFileVersion"
}
else {
  Write-Output "chromedriver is actual"
}

您可以配置相对目录，您需要将chromedriver与$chromeDriverRelativeDir变量放在一起，相对于脚本位置。
