python - 尝试在 Python 中运行 RPY2 并收到错误 0X7e

Question

我正在尝试运行 RPY2 以利用 R 中的 TTR 包，并运行 python 3.8.3 和 R 4.0.2。但是，当尝试运行代码时

os.environ['R_HOME'] = "C:\\Program Files\\R\\R-4.0.2\\bin\\x64"
from rpy2.robjects.packages import importr'

这导致:

OSError: cannot load library 'C:\Program Files\R\R-4.0.2\bin\x64\bin\x64\R.dll': error 0x7e

我主动跑了 python -m rpy2.situation，结果

C:\Users\XXXXX>python -m rpy2.situation
rpy2 version:
3.3.4
Python version:
3.8.3rc1 (tags/v3.8.3rc1:802eb67, Apr 29 2020, 21:39:14) [MSC v.1924 64 bit (AMD64)]
Looking for R's HOME:
    Environment variable R_HOME: None
    InstallPath in the registry: C:\Program Files\R\R-4.0.2
    Environment variable R_USER: None
    Environment variable R_LIBS_USER: None
R version:
R version 4.0.2 (2020-06-22) -- "Taking Off Again"

    In the PATH:
    Loading R library from rpy2: OK
Additional directories to load R packages from:
None
C extension compilation:

operable program or batch file.
    Warning: Unable to get R compilation flags.

非常感谢有关为什么 RPY2 导致此 0x7e 错误的任何帮助。我还卸载并重新安装了 R 和 RPY2，因为我在其他一些帖子的解决方案中发现了这一点。

Answer 1

我在尝试导入 rpy2 库时遇到了同样的问题。当我在环境变量中为 R 添加路径时，我对它进行了排序。
***注册表中的安装路径:C:\Program Files\R\R-4.0.2
尝试使用上述创建系统环境变量的路径，看看它是否有效
