python - 尝试安装 python 数据表时出现 C++ 编译器错误

Question

我正在尝试使用“pip”为python安装“datatable”，如下所示，但出现错误。

pip install datatable

Error shown is:

Find an LLVM installation
  Environment variable LLVM is not set
  Environment variable LLVM7 is not set
  Environment variable LLVM6 is not set
  Environment variable LLVM5 is not set
  Environment variable LLVM4 is not set
  Candidate directory `/usr/local/opt/llvm` not found
  The build will proceed without Llvm support

Determine the compiler
  Environment variable `CXX` is not set
  Environment variable `CC` is not set
  Llvm installation not found, cannot search for the clang++ compiler
  'compiler_cxx'
  Compiler `clang++.exe` is not found
  Compiler `gcc.exe` is not found

Prepare the environment

SystemExit: Suitable C++ compiler cannot be determined. Please specify a compiler executable in the `CXX` environment variable.

我什至为 Python 重新安装了 VC++ Compiler 并进行了更新:

pip install --upgrade setuptools

如果您使用的是 Windows，则可以通过 pip 直接安装数据表。从 0.11 版本开始。现在可以按照 https://datatable.readthedocs.io/en/latest/install.html#install-on-windows 中的说明安装库的开发快照。 .
