- 这个不是 nicegui 的问题.
- 是 Python 顽疾.
- 基于
pyinstaller
等工具打包 Python 项目成 app, 启动都很慢. - 即使是换别的工具, 也会有新的问题. (我 repo 里, 基本都测试了, 都不好用)
启动慢的主要原因:
- 是打包了 Python 解释器, Python 解释器启动很慢. (类似 Java JVM 启动)
- 打包(如果是 onefile), 本质是类似 zip, 存在解压过程.
- 所以, 常态是 10-20s 才能打开. 这个目前是无解的.
- 不光慢, pyinstaller 打包 nicegui (MacOS) 还会出现打开后, 疯狂创建 main 进程(bug). 原因是 pyinstaller 打包
多进程
项目, 有 bug. 而 nicegui 内部实现, 依赖多进程
.
绕行解决办法: (绿色模式)
- 原理: 过去 Windows 平台, 常见的
绿色免安装软件
. - 做法: 打包
Python 解释器
+pip 依赖包
+源码编译结果 pyz
, 一起打包发布. - 优点: 启动快.
- 缺点: 每个平台, 都要打包对应平台的 Python.
