在Windows 10上安装numba和llvmlite Python失败

Question

在Windows 10失败时安装numba和llvmlite Python

我尝试在Windows 10上安装Python

安装numba

部分成功，但安装llvmlite失败

Requirement already satisfied: numpy>=1.15 in c:\users\paul\appdata\local\programs\python\python39\lib\site-packages (from numba) (1.19.2+mkl)

    CMake Error at CMakeLists.txt:9 (find_package):
      Could not find a package configuration file provided by "LLVM" with any of
      the following names:

        LLVMConfig.cmake
        llvm-config.cmake

      Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set
      "LLVM_DIR" to a directory containing one of the above files.  If "LLVM"
      provides a separate development package or SDK, be sure it has been installed.

    -- Configuring incomplete, errors occurred!

不知道LLVM是在哪里安装的？

因此，我使用编辑器添加了值C：\ProgramFiles\mingw-w64\winlibs-x86_64-posix-seh-gcc-9.3.0-llvm-10.0.0-mingw-w64-7.0.0-r4\mingw64\lib\cmake\llvm的LLVM_DIR

希望它将使用我在C:\LLVM\ Clang -1100、C:\LLVM\clang-1000上安装的四个clang版本中的一个.最新的二进制文件是C:\LLVM\clang-1100\LLVM\bin

我还安装了VS 1017和1019，所有编译器都可以从其他IDE和构建中正常工作。

并下载了最新的轮子

llvmlite 0.34.0-cp39-cp39-winamd64.whl

将LLVM_DIR添加到系统路径中。

C:\Program Files\mingw-w64\winlibs-x86_64-posix-seh-gcc-9.3.0-llvm-10.0.0-mingw-w64-7.0.0-r4\mingw64\lib\cmake\llvm

这允许它更接近于工作，但是使用MSVC失败了。

这意味着未指定输出文件夹位置，或者VS增量构建选项未设置为“不使用”。

或者我应该使用LLVM版本，但是我不知道如何指定哪个版本，而不是使用VS2017。

如何走出这个兔子洞最受欢迎的建议;-)

谢谢

我想安装librosa，但是我得到了带有此错误的堆栈，但我设法用以下方法解决了它：

• 首先，我下载了llvmlite 这里的最后一个版本。
• 而不是运行以下命令：

pip install llvmlite-0.35.0-cp39-cp39-win_amd64.whl

• 接下来，通过librosa对所有软件包进行安装，如下所示：

pip install --no-deps packageName

• 或者只是为了获得更多的样本，请如下所示：

pip install librosa --ignore-installed llvmlite
