python安装时出现高山错误

Question

我需要将 Shapely 安装到基于Python + Alpine的docker容器中。我在容器中已经拥有的东西：

make, gcc, geos-dev, musl-dev

我用这个命令得到了什么： pip安装正常

我在Google上搜索了很多时间，但是找不到任何解决方法。

Dockerfile

FROM python:3.7-alpine

RUN ["mkdir", "/home/test"]
WORKDIR /home/test

RUN echo "http://mirror.leaseweb.com/alpine/edge/testing" >> /etc/apk/repositories
RUN echo "http://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories
RUN ["apk", "add", "make", "gcc", "geos-dev", "musl-dev"]

容器内的Python版本

/home/test # /usr/local/bin/python
Python 3.7.5 (default, Oct 21 2019, 20:13:45)

GEOS版本

/home/test # geos-config --version

已更新

现在，您必须将此存储库置于其他存储库的下方：

--repository http://dl-cdn.alpinelinux.org/alpine/edge/community

Answer 1

这将起作用：

r.join(
    r.groupBy("id").count().as("g"),
    $"g.id" === r("id")
  )
  .withColumn(
    "ID_EMPLOYE_VENDEUR",
    expr("if(count != 1, null, ID_EMPLOYE_VENDEUR)")
  )
  .drop($"g.id").drop("count")
  .distinct()
  .show()

请参阅this

更新：根据评论，r已移至id回购。

Answer 2

我的构建也遇到了这个问题。我的解决方法是从Alpine切换到Debian（不理想，但允许我使用旧版本的geos），因为看来最新版本的geos与shape不兼容。
