我无法在 MAC OS 中通过 pip 或 PyCharm 安装 rpy2(Python 包)。
但我可以成功运行Python(通过PyCharm)和R(通过RStudio)......
主要错误信息是
"Error: Tried to guess R's HOME but no command (R) in the PATH." and "Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-OtKzsd/rpy2/".
我猜问题可能与 R 环境 PATH 设置有关？
但我还是不知道如何解决这个问题......
完整的错误消息如下:
host-217:~ ChenGuanYing$ sudo pip install rpy2
The directory '/Users/ChenGuanYing/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

最佳答案
错误消息中建议的两种可能的解决方案:
- 导出 R_HOME=
- 将 R 命令放入系统路径
