在Windows上安裝Python RAWPY軟件包的問題

Question

我想在Python上讀取RAW文件，看來Rawpy軟件包非常適合此操作。 但是，當嘗試使用Windows CMD安裝它時

C:\Users\myself>py -m pip install rawpy

或直接使用Spyder命令行

!pip install rawpy

我收到以下錯誤

最后一個錯誤行明確指出找不到文件external / LibRaw-cmake / CMakeLists.txt 。 您有解決問題的想法嗎？

有關信息，運行這些CMD命令行時其他程序包不會顯示錯誤。 該錯誤實際上取決於rawpy軟件包。

發布時可用的版本（0.12.0）沒有提供Python 3.7輪子，因此pip下載了源代碼發行版並嘗試手動編譯該軟件包。 這失敗了，因為它需要更復雜的開發設置。

現在發布了一個新的rawpy版本0.13.0，並提供了適用於Python 3.7的輪子。 然后，一個簡單的pip install rawpy應該可以工作並下載轉盤，而不是源代碼發行版。
