用命令无法获得Google-Chrome的版本：PowerShell; powerShell; erroractionPreference =＆＃x27; sillysyContinue＆＃x27;将WebDrivermanager与硒一起使用

Question

在使用Selenium和Chrome Driver运行Python脚本时，我会在下面遇到错误。

我使用所讨论的脚本进行一些非常简单的自动化在本地运行（Win 10）。 由于WebDridver无法获得Chrome版本，因此它安装了最新版本，导致脚本在Chrome具有更新时经常失败，但尚未安装。

====== WebDriver manager ======
Could not get version for google-chrome with the command:  powershell "$ErrorActionPreference='silentlycontinue' ; (Get-Item -Path "$env:PROGRAMFILES\Google\Chrome\Application\chrome.exe").VersionInfo.FileVersion ; if (-not $? -or $? -match $error) { (Get-Item -Path "$env:PROGRAMFILES(x86)\Google\Chrome\Application\chrome.exe").VersionInfo.FileVersion } if (-not $? -or $? -match $error) { (Get-Item -Path "$env:LOCALAPPDATA\Google\Chrome\Application\chrome.exe").VersionInfo.FileVersion } if (-not $? -or $? -match $error) { reg query "HKCU\SOFTWARE\Google\Chrome\BLBeacon" /v version } if (-not $? -or $? -match $error) { reg query "HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Google Chrome" /v version }"

此错误消息...

====== WebDriver manager ======

...表示 webdriver-manager 无法检测到 google-chrome 浏览器的版本使用以下任何一个命令：

1. （get -item -path“ $ env：programFiles \ google \ chrome \ chrome \ application \ chrome.exe”）
2. 。 > （get -item-path“ $ env：programFiles（x86）\ google \ chrome \ chrome \ application \ chrome.exe”）
3. 。 \ chrome \ application \ chrome.exe”）。
4. -Item -path“ $ env：localappdata \ google \ chrome BlbeAcon“/v版本
5. reg QUERY”

深度潜水

在该问题似乎是以下任务：

• PowerShell脚本中的一个额外纽线
• 丢失了带有programFiles（x86）的ENV空间（x86）
• 向PowerShell命令 -execution -ececution -ececution -ececution -ececution -ececution -ececution -ececution -ececution -ececution -bypass -nologo -nonInteractive -noprofile -command
• 用四个doublequotes替换单个双重

在拉的某个时候 试标

最后，解决方案是修复powershell的确定和str CONSATINATION ：//github.com/sergeypirogov/webdriver_manager/blob/352bd0ba13e5097935472f978f978f33bbbb908c9c3c3d6d6d6d6d6d/webdriver_manager/utils.manager/utils.py#l147

    ignore_errors_cmd_part = ' 2>$null' if os.getenv('WDM_LOG_LEVEL') == '0' else ''
