调试发现的问题 #

• executable参数值为None
• args参数值为：C:\\ProgramData\\anaconda3\\Lib\\site-packages\\playwright\\..\\..\\..\\..\\bin\\node C:\\ProgramData\\anaconda3\\Lib\\site-packages\\playwright\\..\\..\\..\\node_modules\\playwright\\node_modules\\playwright-core\\cli.js run-driver

Node.exe路径搜索结果 #

系统中存在多个Node.exe实例，但均不在脚本预期的C:\ProgramData\bin目录：

c:\>where /r c:\ node.exe
c:\ProgramData\anaconda3\node.exe
c:\ProgramData\anaconda3\Lib\site-packages\playwright\driver\node.exe

缺失的关键文件 #

脚本预期的文件路径C:\ProgramData\anaconda3\Lib\site-packages\playwright\..\..\..\node_modules\playwright\node_modules\playwright-core\cli.js不存在，Anaconda根目录的node_modules下仅有以下内容：

C:\ProgramData\anaconda3\node_modules
