【问题描述】：

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

【参考方案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。

使用 conda 安装：conda install pymysql 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 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。

【讨论】：

他们正在使用 anaconda，这对于使用哪个版本的 python 也非常明确

@jakub 如果我使用你的命令，我会得到：'python3' 不是内部或外部命令、可运行程序或批处理文件。

@AK28 - 然后使用pip install。不过，我确实建议使用 python -m pip 语法，因为它更明确地说明了您指的是哪个 pip。这可以防止安装到错误的环境中。

@jakub 最后！解决方案 2 对我有用。非常感谢！
