【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 import dash_renderer 并从 package.filename
尝试添加以下但仍然无法解决
- 在我的代码中添加了 import dash_renderer
- 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)
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,在下面遇到错误
my\directory>app_short.exe

运行app_short.py文件可以正常启动flask应用,可以访问html页面,但是exe一直显示AttributeError。
