我正在尝试安装SQLite以便程序包正常工作，但是我一直收到此错误。您知道问题是什么以及如何解决吗？

SQLite的二进制文件似乎有问题，但我不知道到底是什么问题。
谢谢！
编辑：因此，在进行了大量的故障排除之后，我将node.js版本降级为12.0.0，然后重新安装了所有软件包。然后，由于现在已安装SQLite库，因此该命令可以使用。
答案 0 :(得分：0)
主要问题似乎是：
error MSB8020: The build tools for Visual Studio 2015 (Platform Toolset = 'v140') cannot be found. To build using the v140 build tools, please install Visual Studio 2015 build tools.
您可能也要检查此一项=> The builds tools for v120 (Platform Toolset = 'v120') cannot be found
有一条评论开头为“在此上浪费了4个多小时”。
我希望对您有帮助
