Python Mongodb文档无法在Docker中生成

我正试图使用以下Dockerfile构建MongoDB文档的本地副本，如下所示：

FROM python:2 as builder
RUN ["mkdir", "/pythonsrc"]
WORKDIR "/pythonsrc"
RUN ["git", "clone", "https://github.com/mongodb/docs.git", "."]
RUN ["pip", "install", "-r", "requirements.txt"]
RUN ["make", "html"]

# FROM nginx:stable
# COPY --from=builder /pythonsrc/docs/_build/html /usr/share/nginx/html

但是它在

运行[“make”，“html”]

步骤失败，出现以下错误：

INFO:giza.operations.make:running sphinx build operation, equivalent to: giza sphinx --builder html

还有其他人遇到过这个错误吗？是否有修复/解决方法
