运行异常-虚拟环境问题

Boris-code commented 2 years ago

以下异常是虚拟环境下运行报错，正常环境下可以运行

根据报错信息来看，你的虚拟环境是不是没有满足以下条件？或者是你的虚拟机差点什么支持pywebview运行的程序呢？

是虚拟环境下 EdgeHtml没找到？

pangao1990 commented 2 years ago

是的，你的虚拟环境没有webview2，可以安装一下。 EdgeWebView2Runtime的下载地址是 https://developer.microsoft.com/en-us/microsoft-edge/webview2/

Boris-code commented 2 years ago

感谢大佬耐心回答，虚拟环境里不知道咋装这玩意，正常环境下是安装过了，可以跑起来。虚拟环境下 cef模式也跑不起来了

venv虚拟环境换成 virtualenv可以解决

pangao1990 commented 2 years ago

你说的是venv呀，我以为你说的虚拟环境是指虚拟机虚拟出一个新系统呢。我平时用的时候，觉得venv和virtualenv没啥区别。虽然venv是virtualenv集成到标准库中的子集，理论上来说venv功能会比virtualenv少一些。但是我平时使用并没有发现有啥不一样的。不过，你倒是发现了他们的不同，还是你厉害啊

Boris-code commented 2 years ago

哈哈，瞎试呗，没啥，还是大佬你厉害

怎么替换呢，我也报这个错误了

WnagoiYy commented 1 year ago

@pangao1990 @Boris-code 解决了，更新下依赖，.\pyapp\assets\requirements.txt： pywebview==3.6.2 --> pywebview==3.7.2

最后查到问题在3.6.3和3.7版本中修复，pywebview 更新日志 - pyup.io https://pyup.io/packages/pypi/pywebview/changelog

@WnagoiYy 不愧是大佬啊，我已经更新了pywebview的版本号。🙏🙏🙏

谦虚谦虚，你才是大佬，我是个菜鸡。

还有个打包cef的错误完全没头绪（借楼发一下，不开新issue了）：

@WnagoiYy 你好，从这个报错信息来看，我不确定是 upx 这个压缩工具出问题了，还是打包过程中的cefpython3缺失libcef.dll了。不过，我又更新了一版vue-pywebview-pyinstaller，修复了一些pyinstaller打包过程中丢失cefpython3动态链接库的问题，你可以下载新版试试看。

厉害厉害【牛！】，cef能build成功了。我提了个HMR的pr，大佬可以考虑引入一下，要是能解决更新py文件不重启也能hmr就更好了

好的，我看看，然后合并一下代码。🐮🐮🐮
