在 python 设置中找不到和读取文件来打包我的项目

Question

我对 python 打包没有经验。我正在尝试使用命令 python3 -m build 打包我的项目。在安装文件中，我需要打开一些文件，其中包括 VERSION 文件，但我得到了找不到它们的错误。

这就是我在 setup.py 文件中打开它的方式

here = os.path.abspath(os.path.dirname(__file__))
about = {}
with io.open(os.path.join(here, 'my-project', 'VERSION')) as f:
     _version = f.read().strip()
     about["__version__"] = _version 

我得到的错误是：

/private/var/folders/pk/r6xddw312z9d5_rfggl0d5pw0000gn/T/build-via-sdist-trdyv1sv/my-project-0.0.1

还有什么路径

 /private/var/folders/pk/r6xddw312z9d5_rfggl0d5pw0000gn/T/build-via-sdist-trdyv1sv/ 

文件在哪里找不到？

我的最终结果是使用打包的 tar.gz 文件而不是 wheel 文件正确创建了构建文件夹和 .egg-info 文件。因此我认为轮子存在一些问题

Answer 1

我认为您不需要此行中的额外 my-project 引用。

with io.open(os.path.join(here, 'my-project', 'VERSION')) as f:

这会给你带来什么：

with io.open(os.path.join(here, 'VERSION')) as f:

您还可以尝试在主文件夹（setup.py 旁边）中创建一个名为 _version.py 的文件。 然后只需在文件顶部添加 __version__ = '1.107.7'。 您现在可以将其导入 setup.py 中：

from _version import __version__

setup(
    name=NAME,
    version=__version__,
...
