Python使用html解析包Requests-html运行py文件没问题，Pyinstaller打包exe后运行报错
背景
Python利用Requests-html查询百度排名，使用打包指令打包exe
PowerShell 全选
pyinstaller -F apiServer_paiming.py遇到问题
打包后运行exe，出现报错，报错信息如下：

分析问题
apiServer_paiming.py 第14行信息
run_baidu_paiming.py 中第七行信息
通过错误信息，我们可以锁定问题是出在了requests-html中

解决方案
打包exe的时候把打包指令改为：
PowerShell 全选
pyinstaller -F --onefile apiServer_paiming.py --copy-metadata pyppeteer这种方式打包的exe就没有问题了
PowerShell 全选
PS E:\GZ\Python\gz\dist> .\apiServer_paiming.exe
