Spy*_*axi 3 python pyinstaller plotly-dash
使用 PyInstaller 运行从 plotly-dash 代码生成的 exe 文件时,我不断收到以下错误。
AttributeError: 'FrozenImporter' object has no attribute 'filename'

做了一些深入的检查,只能识别出当 dash 尝试导入 dash_renderer并从package.filename行检索文件名时发生的属性错误
尝试添加以下但仍然无法解决
我的情节破折号代码
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.layout = html.Div(children=[
html.H2(children='H-{} Meeting Dashboard'.format("SS"), style={'text-align':'center'}),
html.Div(children=[
html.Div('''Generated on {}'''.format(str(datetime.now())[:19]), style={'text-align':'center', 'font-size':'15px'})
], className='row')]
)
if __name__ == "__main__":
app.run_server(debug=True)

用于生成 exe 文件的 PyInstaller 代码

运行 app_short.py 文件能够正确启动 Flask 应用程序并且可以访问 html 页面,但 exe 一直显示 AttributeError。

我该如何解决这个错误?
我遇到了同样的错误信息,我通过更改解决了它
if __name__ == "__main__":
app.run_server(debug=True)
Run Code Online (Sandbox Code Playgroud)
到
if __name__ == "__main__":
app.run_server(debug=False)
Run Code Online (Sandbox Code Playgroud)
不确定为什么会发生这种情况,或者是否debug=False可以满足您的需求!也许其他人可以详细说明?
