如何正确缓存Python依赖项

作者：涅槃重生武哥 | 来源：互联网 | 2022-10-23 15:12

如何解决《如何正确缓存Python依赖项》经验，为你挑选了1个好方法。

我正在尝试在Dockerfile中构建一个Python项目。我想缓存依赖项，然后在以后使用该缓存，如下所示：

RUN pip3 download -d "/pth/to/downloaded/files" -r /temp/requirements.txt -c /temp/constraints.txt

# much later on in the Dockerfile:

RUN pip3 install --download-cache="/pth/to/downloaded/files" -r requirements.txt -c constraints.txt

问题：假设pip3 download命令正确，--download-cache在查看pip3 --help输出时不再看到选项-是否可以使用新选项pip3 install来引用由生成的依赖项缓存pip3 download？

现在，我收到此错误：

用法：pip install [选项]

没有这样的选项：--download-cache

wovano.. 5

该--download-cache选项已在pip版本8中删除，因为默认情况下它现在使用缓存。因此，您根本不需要指定此选项。我不确定该pip download -d

选项的目的是什么，但是显然它没有在目标目录中创建缓存。您也可以忽略该-d 选项。

以下Dockerfile可以工作：

FROM python:3.7
COPY constraints.txt requirements.txt ./
RUN pip3 download -d .pipcache -r requirements.txt -c constraints.txt
COPY test.txt ./
RUN pip3 install -r requirements.txt -c constraints.txt



如果添加--cache-dir 
到都在download和install命令，它也能发挥作用。因此，以下Dockerfile也适用：

FROM python:3.7
COPY constraints.txt requirements.txt ./
RUN pip3 download --cache-dir ./tmp/pipcache -r requirements.txt -c constraints.txt
COPY test.txt ./
RUN pip3 install --cache-dir ./tmp/pipcache -r requirements.txt -c constraints.txt


输出示例（仅在pep8和pylint中requirements.txt）：
