您好，我想将我的 chrome 驱动程序更新到最新版本，但 Ant 找到有关更新驱动程序的任何信息，只是有关安装它的信息。我需要做什么才能将驱动程序更新到最新版本？

最近我发现chromedriver现在几乎是一对一的版本(chromedriver 2.46 有最后三个版本的支持策略)。请参阅此处的版本选择指南:https://sites.google.com/a/chromium.org/chromedriver/downloads/version-selection
我已经 wrote simple powershell script用于更新 chromedriver自动地。
需要更新时运行此脚本 crhomedriver (就像 CI/CD 中的构建步骤，就在运行 selenium Web 测试之前):

[CmdletBinding()]
param (
    [string]$ChromeDir="C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
)

if (-Not (Test-Path $ChromeDir -PathType Leaf)) {
  Write-Output "Chrome not found in '$ChromeDir'. Please, install chrome or specify custom chrome location with -ChromeDir argument."
  Exit 1
}

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

$chromeDriverRelativeDir = "Selenium"
$chromeDriverDir = $(Join-Path $thisScriptRoot $chromeDriverRelativeDir)
$chromeDriverFileLocation = $(Join-Path $chromeDriverDir "chromedriver.exe")
$chromeVersion = [System.Diagnostics.FileVersionInfo]::GetVersionInfo($ChromeDir).FileVersion
$chromeMajorVersion = $chromeVersion.split(".")[0]

if (-Not (Test-Path $chromeDriverDir -PathType Container)) {
  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"
}

您可以配置需要放置的相对目录 chromedriver与 $chromeDriverRelativeDir变量，相对于脚本位置。
