ERROR while trying to install rpy2 using pip

Question

I'm trying to install rpy2 using pip install rpy2 on the command shell, but I get the following ERROR:

Collecting rpy2 Using cached https://files.pythonhosted.org/packages/c7/43/401afad8556bf92b08bd7d422cacac614b0e8dd2bce31848318bbcb18f48/rpy2-3.0.5.tar.gz ERROR: Complete output from command python setup.py egg_info: ERROR: Traceback (most recent call last): File "c:\\users\\pablo\\appdata\\local\\programs\\python\\python36-32\\lib\\site-packages\\setuptools\\msvc.py", line 477, in init self.vc_ver = self.find_available_vc_vers()[-1] IndexError: list index out of range

Answer 1

From the looks of it you are missing Microsoft Visual Build Tools. Try installing it: https://visualstudio.microsoft.com/visual-cpp-build-tools/

Then, restart your computer and update setup tools.

pip install --upgrade setuptools 

Once that it done, try installing rpy2 again.

Hope this help!

Answer 2

您可以通过在网页上搜索从https://www.lfd.uci.edu/~gohlke/pythonlibs/下载rpy2的二进制文件，然后使用pip install'that binary file'根据您的python版本下载二进制文件
