过时错误: 未安装'wheel'包。

Question

在尝试部署Python代码时，我们遇到了以下弃用错误。我们正在使用Python 3.7.12。我们尝试安装wheel包作为部署的一部分，但没有成功。我们需要指定任何特定版本的wheel吗？您能否提供一些帮助？

这些应该是警告，而不是实际错误。请检查包是否已经安装。如果失败，请确保创建一个 [mre]。请按照步骤进行操作，从创建新的虚拟环境开始，以重现问题。请注意 pip 和 Python 的版本。 - Karl Knechtel

谢谢。我们通过实施答案部分分享的以下解决方案解决了这个问题。 - Partha

Answer 1

我们已经在安装命令中添加了一个标志“--use-pep517”，以解决版本问题。因此，下面提供了运行 requirement.txt 文件的最终脚本，其中包含我们所有的包。

pip install -r requirements.txt --use-pep517

不是解决方案，只是在新版本的pip中隐藏问题的一种方式。 - stats con chris

Answer 2

安装wheel包应该解决警告中建议的问题。

您只需确保在安装有问题的包之前，单独使用pip install调用安装它，而不是将wheel添加到requirements.txt中，这样它可以用于为您要安装的包构建轮子。

假设您正在使用Docker部署代码，这里是一个示例的Dockerfile：

FROM locustio/locust:2.15.1 # sample base image

COPY requirements.txt .

RUN pip install wheel
RUN pip install -r requirements.txt

# RUN pip install wheel -r requirements.txt <- this won't fix a problem

如果您不想要额外的图像层，您也可以通过单个RUN命令实现相同的效果。

RUN pip install wheel && pip install -r requirements.txt

Answer 3

已废弃：正在使用遗留的setup.py install方法安装spacy，因为它没有pyproject.toml并且未安装wheel包。 pip 23.1将执行此行为更改，可能的替代方案是启用--use-pep517选项。
