无法使用 Anaconda 提示安装 pip PyMySQL

Question

我尝试在我的 Anaconda 提示符下下载 pip 安装 PyMySQL（我使用 Spyder 作为 IDE）。 它不工作。 我收到了这个错误。 有谁知道如何解决它？ 我正在使用 Python 版本 3.7.4 64 位。 先感谢您：）

(base) C:\Users\AK>pip install PyMySQL

Answer 1

这可能是由于您计算机上的防病毒软件或其他程序干扰了网络连接（请参阅pip 安装不工作）。

我可以使用以下内容安装 PyMySQL：

pip install PyMySQL

有几种可能的解决方案。

1. 使用 conda 安装： conda install pymysql
2. 下载 PyMySQL 的轮子并使用该文件安装它。
   • Go 到https://pypi.org/project/PyMySQL/#files并下载.whl文件。
   • 运行pip install path/to/PyMySQL-0.9.3-py2.py3-none-any.whl
3. 如果防病毒实际上在起作用，那么我不确定该怎么做，但谷歌是你的朋友。
