Question

我正在尝试在自己的Python应用程序上使用py-spy，该应用程序的开发和部署主要发生在Docker容器即python:3.7-alpine中。当我在virtualenv中本地运行pip install py-spy时，它会成功。此外，pypi has a listing for it。

奇怪的是，当我将其包含在Pipfile中时，pipenv install无法在Docker容器中找到它，并且在尝试构建时失败。 但是它会正确找到并安装其他Pipenv内容。

Dockerfile看起来像这样：

FROM python:3.7-alpine3.8
RUN mkdir -p /opt/app
WORKDIR /opt/app
RUN set -ex \
    && apk add libpq shadow \
    && apk add --no-cache --virtual .build-deps \
            gcc \
            git \
            bash \
            tmux \
            make \
            libcurl \
            curl-dev \
            libc-dev \
            musl-dev \
            linux-headers \
            pcre-dev \
            postgresql-dev \
            postgresql-libs \
            libffi-dev \
            ncurses-dev \
            python3-dev

RUN pip install pipenv
COPY Pipfile Pipfile.lock ./
RUN pipenv install --system --deploy --dev

# This is where we fail

没有py-spy，整个过程就会建立。使用py-spy = "*"，运行pipenv lock && docker-compose build，我们得到了

这会响吗？ py-spy具有Rust依赖关系，有没有办法检查它在某些架构中是否“不可见”？

是this：

高山python退出了许多Linux轮子：pypa/pip#3969 (comment)。在Alpine Docker容器上安装py-spy之前，请执行以下操作：

echo 'manylinux1_compatible = True' > /usr/local/lib/python3.7/site-packages/_manylinux.py

pip / pipenv在Docker容器中找不到包？
