【问题描述】：
这是我的requirements.txt 文件的一部分。
pystan
cython
lunardate
holidays
convertdate
plotly
fbprophet
在使用 pip install 时，所有的包都按照预期以相同的顺序下载、构建和安装。
但是，为了构建fbprophet 的wheel，它需要pystan 作为依赖项。并且由于pystan当时处于“已构建”阶段并且尚未安装，因此fbprophet安装总是失败。
在上面的 requirements.txt 上使用 pip 我得到了这个日志：

【问题讨论】：
-
我认为没有办法一次性安装所有内容。将
requirements.txt拆分为两个阶段——首先，安装pystan（可能还有cython），然后安装fbprophet。 -
或者在安装
requirements.txt文件之前运行命令pip install pystan -
我正在尝试构建一个 Google App Engine。在标准环境中，我只能提供这个
requirements.txt文件，它会处理其余部分。不能真正编写命令（需要一个灵活的又名付费环境）。所以我真的很想知道是否有办法在 GAE 中为标准运行时做到这一点 -
@SayanSil 你能解决这个问题吗？我遇到了同样的问题
