我正在尝试在 Python 3.9 上使用 pip 安装 cld3。我已经成功安装了 protoc 并且还使用 Visual Studio 获得了 C++ 构建工具，但是当我运行py -m pip install -U pycld3它时失败并显示一些消息。我在运行 Python 3.9 的 Windows 10 上它最初无法使用轮子构建：

这并不奇怪，因为它在文档中提到我的操作系统不支持轮子安装。但是我真的不明白接下来会发生什么：

据我所知，这是因为它找不到“cld3/pycld3.cpp”。我需要运行早期版本的 Python 吗？提前致谢

这是 pycld3 中的一个错误：他们忘记将源代码包含到 sdist 中。请报告错误。

同时解决方法是安装 Cython：

pip install Cython
pip install pycld3

[pycld3 维护者] 这个问题应该在 pycld3 release 0.22中得到解决。

python3 -m pip install -U pycld3

正如@phd 指出的那样，这是 0.21 中的分发上传错误，忽略了包含中间 .cpp 文件。在 sdist 中包含该文件不应依赖于用户是否拥有或想要使用 Cython 的构建时逻辑。

请注意，在 0.22 版本中，安装将尊重环境变量USE_CYTHON=1。您必须具有现有的 Cython 安装才能使用此标志。它将强制从源 .pyx 文件重新编译。这遵循分发 Cython 模块中推荐的行为。

0.22 还放弃了对生命周期结束的 Python 3.5 的支持，并且不再通过 Windows MSVC 上不受支持的 -std=c++11。

详细信息：从 0.21 到 0.22 的完整变更日志。
