使用 pip 安裝 matplotlib 會出現錯誤

Question

我想將 matplotlib 導入我的 python 代碼，但不幸的是它在安裝時出錯。 我可以成功安裝 numpy 但是在安裝 matplotlib 時出現異常錯誤。 我正在使用 Python 3.7.0 版本。

python -m pip install matplotlib

我使用了上面的命令。cmd 中出現了以下錯誤。

C:\Users\ASUS>python -m pip install matplotlib

我用與上述相關的幾個命令嘗試了幾次，然后重新啟動並再次嘗試。 但無法安裝。 由於我是新手，任何人都可以幫我解決這個問題。 先感謝您。

首先檢查“python”代碼是否正確響應。 使用“C:\”路徑，您可以使用“cd..”代碼更改路徑，然后嘗試代碼“pip install matplotlib”。
