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,只能识别当 dash 尝试 import dash_renderer 并从行 package.filename
检索文件名时发生的属性错误尝试添加以下内容但仍然无法解决
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)
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,遇到如下错误
my\directory>app_short.exe

运行app_short.py文件能够正常启动flask应用,并且可以访问html页面,但是exe一直显示AttributeError。

如何修复此错误?
我遇到了同样的错误消息,我通过更改解决了它
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,或者使用
debug=False
运行是否可以满足您的需求!也许其他人可以详细说明?
app.run_server(调试=False)
开发工具通常在开发过程中用于调试,对于生产可执行文件来说不是必需的。
