python - 如何在 colab.research 上安装 rpy2？

Question

如何在 colab.research.google 上安装 rpy2？我尝试了以下命令:

pip install rpy2 
import rpy2

但它不起作用。这是得到的错误:

Collecting rpy2

Complete output from command python setup.py egg_info:
Error: Tried to guess R's HOME but no command 'R' in the PATH.

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-je87ula0/rpy2/

预先感谢您的帮助，伊内斯。

Answer 1

编写 !pip install rpy2 而不是 pip install rpy2

编辑

根据rpy2的文档可以找到here :

Running Rpy2 will require compiled libraries for R, Python, and readline; building rpy2 will require the corresponding development headers (check the documentation for more information about building rpy2).

所以，这应该有效

!apt-get install r-base
!pip install rpy2
