Question

所以我得到main.py我通过PyInstaller main.exe变成了--onefile，但main.exe仍然需要img.png文件夹中的图像文件\data它与main.py/main.exe ...

位于同一文件夹中

img_l = pygame.image.load(os.path.join('data', 'img.png'))
screen.blit(img_l, (0, 0))

如何正确包装这些图像？我现在用pygame.image.tostring搞乱了一段时间，然后尝试将其保存到.txt文件中，以便我可以使用.txt文件夹中的data文件代替img.png的{{1}}，然后我可以使用pygame.image.fromstring（也许），但我还没弄明白如何让它发挥作用。

我甚至不确定这是否正确/可行。

任何想法/建议真诚地赞赏。

我对fromstring和tostring方法了解不多，但您可以随时提供图像为base64数据。 Pygame似乎需要一个实际的图像文件而不仅仅是一个blob 二进制数据所以在下面的例子中，我已经包含3个小图标作为base64字符串写入名为“data”的子文件夹中的文件。然后传递文件名到pygame.image.load()。

我用pyinstaller --onefile filename.py测试了这段代码它没有任何手动更改设置/规格/路径等工作正常。

    """

    and an absolute path to the data/asset folder.

    instead to ensure integrity

    first_run = False
    if not os.path.isdir(asset_dir):
        os.mkdir(asset_dir)

        asset = asset_dict[label]
        filename = os.path.join(asset_dir, asset["filename"])
        rewrite = False
        # no need to check file if we just created the data folder
        if not first_run:

                with open(filename, "rb") as f:
                    if not hashlib.md5(f.read()).hexdigest() == asset["md5"]:

                        rewrite = True
        if first_run or rewrite:

        time.sleep(0.2)
        pos1 += 20
        pos2 += 20
        pygame.display.update()

我将图像转换为base64字符串，如下所示：

import base64

with open(img_input, "rb") as f:
    with open(img_output_b64, "wb") as f2:
        f2.write(base64.b64encode(f.read()))

我该如何打包图片？ -Pygame -PyInstaller
