Unknown error: Failed to create Chrome process
Unknown error: Failed to create Chrome process
我正在为自动测试目的更新 Selenium 和 chromedriver。 我将 chromedriver 和 Chrome 更新到版本 98，并将 Selenium v.3.3.3 升级到 4.1.0。
但我现在每次尝试 运行 我的测试脚本时都会遇到未知错误。整个追溯如下：

我的 PATH 上有 Chrome，但这似乎没有什么不同。在 Chrome 属性的 'Compatibility' 选项卡下，我检查了 'Run this program as administrator' 但是，同样，这没有用。我不知道还能做什么。
编辑 1：
Anaconda 发行版位于我的 C 盘上。 selenium 目录位于 Anaconda 目录中。当我更新 selenium 时，我在回溯中得到了 ModuleNotFoundError: 'certifi':
Traceback (most recent call last):

ModuleNotFoundError: No module named 'certifi'
所以为了修复这个错误，我进入 remote_connection.py 并将下面的前两行添加到文件中。
import sys
sys.path.append('/Anaconda/Lib/site-packages/pip/_vendor')
import logging
import socket
import string
import os
import certifi
import urllib3
import platform
然后我又收到另一个关于 testcase.ini 的错误，这是包含被测系统 IP 的配置文件、应用程序的登录信息等。

OSError: Cannot load C:\Anaconda\Lib\site-packages\pip\_vendor\TestPlans\TestCases\testcase.ini
testcase.ini每次自动化测试都是运行读取。 ConfigLoader class returns 给定模块名称和相对于 ConfigLoader 的文件路径的配置对象。所以我进入 ConfigLoader.py 并将下面 try/except 块中的 -1s 更改为 -2s:
try:
if self.package:
#If a package is given, use the last entry in sys.path which goes up a directory, and drill down into the package
path = sys.path[-2] + "//" + self.package
else:
#If not, use the information stored in sys.path, and assume we want to look in TestPlans/TestCases
path = sys.path[-2] + "//TestPlans//TestCases"
这就是我如何得出我第一次发布的未知错误。
testcase.ini也是选择浏览器和存放驱动路径的地方。它看起来像这样：
; parameters for test framework

DRIVER_PATH = C:\Anaconda\

; FIREFOX_PATH = C:\Program Files\Mozilla Firefox\firefox.exe
chrome.exe 有两个副本，一个在 Program Files 中，另一个在 Program Files (x86) 中。不知道为什么在两个不同的C盘子目录下会有两个单独的Google目录。
无论如何，我删除了 Program Files 中的 Google 目录并保留了 (x86) 中的目录，现在我的测试脚本再次 运行。
