(Python/VS Code) 無法安裝 scipy

Question

我似乎無法使用 VS Code 安裝 scipy。

python -m pip install scipy 使用緩存的 scipy-1.5.2.tar.gz (25.4 MB) 收集 scipy 安裝構建依賴項...完成獲取構建輪子的要求...完成准備輪子元數據...錯誤錯誤：命令出錯退出狀態為 1：命令：'C:\\Users\\bundyjas\\AppData\\Local\\Programs\\Python\\Python39\\python.exe''C:\\Users\\bundyjas\\AppData\\Local\\Programs\\Python\\Python39\\lib\\站點包\\pip_vendor\\pep517_in_process.py' prepare_metadata_for_build_wheel 'C:\\Users\\bundyjas\\AppData\\Local\\Temp\\tmpmkxabgvf' cwd: C:\\Users\\bundyjas\\AppData\\Local\\Temp\\pip-install-4lff13ycip-4lff13y48\\Complete輸出（195 行）：setup.py:460: UserWarning: Unrecognized setuptools command ('dist_info --egg-base C:\\Users\\bundyjas\\AppData\\Local\\Temp\\pip-modern-metadata-j_sx_haa')，繼續生成 Cython 源並擴展模板 warnings.warn("Unrecognized setuptools command ('{}'), 繼續" 從 SciPy 源目錄運行。 lapack_opt_info: lapack_mkl_info: No module named numpy.distutils 中的“numpy.distutils._msvccompiler”； 嘗試從 distutils 自定義 MSVCCompiler 庫 mkl_rt 在 ['C:\\Users\\bundyjas\\AppData\\Local\\Programs\\Python\\Python39\\lib', 'C:\\', 'C:\\Users\\bundyjas\\AppData\\Local\\ Programs\\Python\\Python39\\libs'] 不可用

從源代碼安裝 scipy非常苛刻，不推薦使用，尤其是在 Windows 上。 您的日志已經表明需要 C/C++/Fortran 編譯器，后者用於 OpenBLAS。 （在 1.0 之前，有很多年沒有正式的二進制版本！）

當沒有找到合適的預制二進制文件時，就會從源代碼安裝，就像你的情況一樣。

原因在這里：您使用的是 Python 3.9，它太新了（10 月 5 日：現在 < 2 周）。 目前還沒有官方的預制 scipy 版本。 暗示

使用 Python <= 3.8。 （相信我：您不想在 Windows 上從源代碼安裝）。

（這與 VS Code 完全無關/正交）
