python - 如何将所有 python 代码捆绑到一个 zip 文件中？

Question

在分发应用程序时将所有的鸡蛋合并到一个 zip 文件中会很方便，这样您只需要分发一个 zip 文件和一个可执行文件(一些自定义二进制文件，只需启动, 加载 zip 文件的主要功能并启动 python 或类似功能)。

我在网上看到过一些关于这样做的讨论，但没有关于如何实际做到这一点的示例。

我知道您可以(如果它是 zip 安全的)将鸡蛋转换为 zip 文件。

我不确定的是:

你能以某种方式将所有鸡蛋合并成一个 zip 文件吗？如果有，怎么做？

您将如何从特定的 egg 加载和运行代码？

您如何确保该 egg 中的代码可以访问所有依赖项(即 zip 文件中的其他 Egg)？

人们经常问这类问题并得到诸如此类的答案；使用 py2exe。是的，我明白了，这是一种解决方案。不过，这不是我要在这里问的问题...

Answer 1

您可以使用常规 Python 工具自动完成大部分工作。让我们从干净的 virtualenv 开始。

[zart@feena ~]$ mkdir ziplib-demo
[zart@feena ~]$ cd ziplib-demo
[zart@feena ziplib-demo]$ virtualenv .
New python executable in ./bin/python
Installing setuptools.............done.
Installing pip...............done.

现在让我们安装一组将进入压缩库的软件包。诀窍是强制将它们安装到特定目录中。

(注意:不要在命令行或 pip.conf/pip.ini 中使用 --egg 选项，因为它会破坏文件布局，使其无法在 zip 中导入)

[zart@feena ziplib-demo]$ bin/pip install --install-option --install-lib=$PWD/unpacked waitress
Downloading/unpacking waitress
  Downloading waitress-0.8.5.tar.gz (112kB): 112kB downloaded
  Running setup.py egg_info for package waitress

Requirement already satisfied (use --upgrade to upgrade): setuptools in ./lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg (from waitress)
Installing collected packages: waitress
  Running setup.py install for waitress

    Installing waitress-serve script to /home/zart/ziplib-demo/bin
Successfully installed waitress
Cleaning up...

更新:pip 现在有 -t <path>开关，其作用与 --install-option --install-lib= 相同.

现在让我们将它们全部打包到一个 zip 中

[zart@feena ziplib-demo]$ cd unpacked
[zart@feena unpacked]$ ls
waitress  waitress-0.8.5-py2.7.egg-info
[zart@feena unpacked]$ zip -r9 ../library.zip *

[zart@feena unpacked]$ cd ..

请注意，这些文件应该在 zip 的顶部，不能只是 zip -r9 library.zip unpacked

检查结果:

[zart@feena ziplib-demo]$ PYTHONPATH=library.zip python

更新:从 python 3.5 开始还有 zipapp module这可以帮助将整个包捆绑到 .pyz 文件中。对于更复杂的需求pyinstaller , py2exe或 py2app可能更符合要求。
