LXML錯誤

我試圖運行在命令提示符下的命令 -LXML錯誤

pip install -r requirements.txt

但它顯示了許多錯誤，我不知道如何解決這些問題作爲我不是熟悉python。

的錯誤是： 1.

請幫我解決這些問題，我需要它的一個項目，我真的需要把它完成。我在Windows 10（Intel處理器）和Python3.4上。

[如何在Windows上安裝lxml]可能的重複（https://stackoverflow.com/questions/29440482/how-to-install-lxml-on-windows） – Tomalak

正如@SaeX在this answer中所說的，您可以找到預編譯的 WHL的lxml，其中包含所需的模塊和依賴關係here。

對於Python 3.4和win10，你的文件應該是lxml‑4.1.0‑cp34‑cp34m‑win_amd64.whl。

pip install lxml‑4.1.0‑cp34‑cp34m‑win_amd64.whl

對於Python 3.4或以上，

在命令提示符下，型PIP 3，如果你想下載和網絡安裝安裝LXML的情況下：然後你就可以使用畫中畫安裝自動 otheriwse，請從以下

LXML的.whl文件對於32位：Download Here

對於64位：Download Here

下載車輪文件後，瀏覽您的命令提示符下，其中.whl文件被下載和位置，然後嘗試 PIP3安裝「下載WHL文件名」
