问题描述

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 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

  1. import dash_renderer添加到我的代码中
  2. 将 dash 和 dash_renderer 包文件夹复制到 dist/{app}/ 文件夹中

我的破折号代码

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)

PyInstaller 用于生成 exe 文件的代码

\path\to\python37\python.exe -m PyInstaller app_short.py

运行.exe文件时出错,在下面遇到错误

my\directory>app_short.exe

Traceback (most recent call last):

  File "site-packages\dash\dash.py", line 1359, in <listcomp>
AttributeError: 'FrozenImporter' object has no attribute 'filename'
[16716] Failed to execute script app_short

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

如何修复此错误?

解决方案


我遇到了同样的错误信息,我通过更改解决了

if __name__ == "__main__":
    app.run_server(debug=True)

if __name__ == "__main__":
    app.run_server(debug=False)

不知道为什么会发生这种情况,或者是否debug=False可以根据您的需要运行!也许其他人可以详细说明?
