无法使用 Anaconda 提示安装 pip PyMySQL

Question

我尝试在 Anaconda 提示符下下载 pip install 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 3.7.4 64 位版本。提前谢谢你:)

(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 install is not working）。

我可以通过以下方式安装 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 wheel 并使用该文件进行安装。
   • 转到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. 如果杀毒软件确实发挥了作用，那么我不知道该怎么办，但 google 是你的朋友。
