Could not build wheels for pymssql which use PEP 517 and cannot be installed directly

回答: 出现"Could not build wheels for pymssql which use PEP 517 and cannot be installed directly"的错误是由于缺少编译所需的工具或库。根据引用，你需要安装Microsoft Visual C++ 14.0或更高版本。你可以从"https://visualstudio.microsoft.com/visual-cpp-build-tools/"下载并安装Microsoft C++ Build Tools。另外，根据引用，你可以尝试更新pip和setuptools来解决此问题，可以使用以下命令更新pip和setuptools:
python -m pip install --upgrade pip
python -m pip install --upgrade setuptools

如果你仍然遇到问题，你可以尝试从"https://www.lfd.uci.edu/~gohlke/pythonlibs/#pymssql"下载与你的Python版本和系统匹配的pymssql的预编译二进制文件。根据引用，下载后将文件复制到你的项目目录或Python安装目录的Scripts文件夹中。然后你可以使用pip命令安装pymssql。希望这些步骤能够帮助你解决问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
