Python pyinstaller打包pyechart的最佳方法

个人博客,欢迎来撩 fangzengye.com

1. 打包pyechart错误信息

FileNotFoundError: [Errno 2] No such file or directory: ‘C:\Users\xxx\AppData\Local\Temp\_MEI944442\pyecharts\datasets\map_filename.json’

2.原因： pyinstaller与yechart不兼容
3.方法：在PyInstaller安装目录下

• \AppData\Roaming\Python\Python37\site-packages\PyInstaller\hooks\ 需要增加如下文件，

hook-pyecharts.py 文件内容：

# Hook for nanite: https://pypi.python.org/pypi/nanite 
from PyInstaller.utils.hooks import collect_data_files 
datas = collect_data_files('pyecharts') 

然后删除工程下面xxxxx.spec 文件，重新打包，即可。
