PyCharm 無法安裝 kiwisolver

Question

我正在嘗試安裝 kiwisolver 以便稍后導入到 python 文件中。 每當我嘗試安裝它時，它都不起作用。 這是來自終端的摘錄，其中包含整個錯誤消息：

pip install kiwisolver

使用緩存的 kiwisolver-1.2.0.tar.gz (52 kB) 收集 kiwisolver

我需要做什么來安裝 kiwisolver？

我正在使用帶有 Python 3.9(venv) 解釋器的 PyCharm 社區版 2020.2.3。

Answer 1

不確定 Python 3.9 中是否有適用於 kiwisolver 的輪子，請檢查此處並下載並安裝正確的輪子（如果有）。 如果沒有下載 3.8 Python 版本。
