Question

使用PyInstaller运行从散点代码生成的exe文件时，我始终收到以下错误。

AttributeError: 'FrozenImporter' object has no attribute 'filename'

进行了一些深入的检查，仅能确定在短划线试图 导入dash_renderer 并从 < em> package.filename

试图添加以下内容，但仍然无法解决

将导入dash_renderer 添加到我的代码中
将dash和dash_renderer软件包文件夹复制到dist / {app} /文件夹中

我的破折号

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

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

运行.exe文件时出错，请在下面遇到错误

my\directory>app_short.exe
2019-06-25 23:36:55 Imported all modules
Traceback (most recent call last):
  File "app_short.py", line 24, in <module>

  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flask应用程序，并且可以访问html页面，但是exe始终显示AttributeError。

如何解决此错误？

Answer 1

我遇到了相同的错误消息，并且通过更改

解决了该错误消息

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

到

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

不确定为什么会发生这种情况，或者不确定是否可以使用debug=False来满足您的需求！也许其他人可以详细说明？

AttributeError：“ FrozenImporter”对象没有属性“文件名”
