使用setup.py安装软件包时出现问题

问题描述：

我已经设置了setup.py，以从我从项目的虚拟环境中生成的requirements.txt中获取依赖项.如下:

I have setup.py set to get the dependencies from requirements.txt that I generate from my virtual environment of the project. As follows:

在我的视线中:

pip3 freeze > requirements.txt

然后:

with open('requirements.txt') as f:
    required = f.read().splitlines()

setuptools.setup(
    ...
    install_requires=required,
    ...
)

但是当我尝试安装我的软件包时，显示了此错误:

But I have this error displayed when I try to install my package:

raise RequirementParseError(str(e))
pip._vendor.pkg_resources.RequirementParseError: Parse error at "'(===file'": Expected stringEnd

因此，当检查我的requirements.txt文件时，我发现这一定是软件包安装失败的根本原因:

So when checking my requirements.txt file, I found this which must be the root cause of package installation failure:

avro-python3===file-.avro-VERSION.txt

我没有明确安装它，这是一个传递依赖.当我尝试安装avro-python3时，出现以下错误:

I didn't install it explicitly it is a transitive dependency. And when I try to install avro-python3 it, I get the following error:

Requirement already satisfied: avro-python3 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (file-.avro-VERSION.txt)

该如何解决我的问题?

谢谢.

答

发生此错误是因为 setup 方法不希望版本具有 file-.avro-VERSION格式.txt .我怀疑字符-"是否包含是解析器困扰的原因，因为它希望字符串以结尾而不是该字符结尾.

This error happens because the setup method is not expecting a version to have the format file-.avro-VERSION.txt. I suspect that the character "-" is what bothers the parser, as it expects the string to end instead of that character.

我建议您尝试在 requirements.txt 文件，问题应该消失了.

I suggest you try to use one of the official versions on the requirements.txt file and the problem should be gone.
