【问题描述】：

我收到“系统找不到指定的路径”错误。

谁能给我一些关于如何使路径正确的提示？

我在使用 pip 时从未遇到过此类错误。

【问题讨论】：

pymssql 2.1.3 为 Python 3.5 预先构建了 wheel 文件，因此 pip 会尝试从源代码构建它很奇怪。您可以尝试从 PyPI（64-bit Python 或 32-bit Python）下载适当的 Wheel 文件并尝试安装。

Cannot install pymssql on windows的可能重复

【参考方案1】：

看看这个https://docs.microsoft.com/en-us/sql/connect/python/pymssql/step-1-configure-development-environment-for-pymssql-python-development

要选择正确的文件下载，您必须确定 cp 的数量 例如：cp27、cp36 等

import pip
print(pip.pep425tags.get_supported())

像这样： enter image description here

【参考方案2】：

通过 anaconda 使用 Python 的人，应以管理员身份在 anaconda 命令行中运行以下代码。

conda 安装 pymssql。

我已经测试并且工作正常，这大约需要 20-30 分钟，同时它还会安装所有其他依赖项。
