python - PyInstaller 打包 Flask 应用程序无法加载 Python 库，dlopen -> 找不到图像

Question

我已经打包了一个this simple flask app使用 PyInstaller 但我的 OSX 可执行文件无法运行并显示以下可执行文件，

Error loading Python lib '/Users/ahmed/Code/play/py-install-tut/dist/myscript.app/Contents/MacOS/Python': dlopen(/Users/ahmed/Code/play/py-install-tut/dist/myscript.app/Contents/MacOS/Python, 10): image not found

我的猜测是 PyInstaller 没有将 Python 与我的应用程序一起打包。这是我跑的，

$ pyinstaller hello_flask.spec --onedir

当我在 OSX 中打开打包应用程序的内容时，我得到以下文件，

myscript.app/Contents/MacOS/
  _struct.cpython-34m.so
  hello_flask
  zlib.cpython-34m.so

当我双击上面的 hello_flask 可执行文件时，我在终端中得到以下输出，

/Users/ahmed/Code/play/py-install-tut/dist/myscript.app/Contents/MacOS/hello_flask ; exit;

我也尝试在同事的 mac OSX 上运行此程序，但遇到了同样的问题。

我确实意识到这是一篇旧帖子，但刚刚遇到了同样的问题，并找到了一个可能的解决方案 - 以防万一其他人发现它有用。也许这并不理想，我确信某些地方一定缺少一些东西，但无论如何......

pyinstaller 在 dist 目录中创建一个 myscript 目录和一个 myscript.app 文件。我设法通过手动将 dist/myscript 中的所有内容复制到 myscript.app/Contents/MacOS 中来运行应用程序

之后myscript.app文件成功为我启动了程序，并且也可以在没有myscript目录的情况下进行分发。

不知道为什么 pyinstaller 不会自动复制所有内容。
