如何在使用 pip 为 requirements.txt 中的其他包构建​​轮子之前安装某些包？

Question

Here is a section of my requirements.txt file.

pystan
cython
lunardate
holidays
convertdate
plotly
fbprophet

While using pip install, all the packages are downloaded, built and installed in the same order as expected.

However, for building the wheel of fbprophet , it needs pystan as a dependency. And since pystan is in a "built" stage then and not yet installed , the fbprophet install always fails.

On using pip on the above requirements.txt I get this log:

Answer 1

I got the same error message when I ran what you had above, but was able to pip install -r requirements.txt with this as my requirements.txt :

pystan==2.19.1.1
cython
lunardate
holidays
convertdate
plotly
fbprophet

pip was likely using an unsupported version of pystan . According to the fbprophet installation documentation , as of January 20th 2022 (when I am writing this), ' fbprophet currently does not support pystan >=3.0.'
