C++；尝试安装python datatable时出现编译器错误

我试图使用下面的'pip'为python安装'datatable'，但我遇到了错误

pip install datatable

显示的错误是：

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

我甚至重新安装了用于Python的VC++编译器，并更新了：

pip install --upgrade setuptools

---

如果您在Windows上，那么从0.11版开始，datatable将可以通过

pip

直接安装。现在，可以按照上的说明安装库的开发快照。

setuptoools不是VC++编译器，您必须自己安装。您要在哪个操作系统上安装它？您需要安装一个C编译器，如GCC或clang。您可以将指向VC++编译器二进制文件所需的一个环境变量设置为hack。我建议安装Visual Studio Build Tools

请阅读精细手册（）：“当前datatable无法在Windows上工作”

pip install --upgrade setuptools
