Answer 1

更改msvs-version：

  

npm config set msvs_version 2015

它对我有用。

Answer 2

问题是您使用的是不支持的节点版本。

您使用的节点版本为5. **，oracle db模块支持节点4,6和7。

来源是模块的git。

请将节点版本升级到6或7。

Power shell：

Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install -g npm-windows-upgrade
npm-windows-upgrade

或使用nvm：

nvm install 6
nvm use 6

在环境变量中，确保指向 Python 2.7 且仅指向2.7。*。

无需卸载所有其他pythones版本。

告诉我如何发展;

祝你好运，
