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

我编写了简单的Powershell脚本来自动更新chromedriver。

当您需要更新crhomedriver时运行此脚本(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)GoogleChromeApplicationchrome.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chromedriver的相对目录$chromeDriverRelativeDir变量，相对于脚本位置。

chromedriver 是一个独立的可执行文件。 只需将现有版本替换为较新的版本即可。

1. 从 https://sites.google.com/a/chromium.org/chromedriver/downloads 下载最新版本的chromedriver_win32.zip
2. 解压缩文件以提取ChromeDriver.exe
3. 将现有文件替换为此新可执行文件。
