我有一个简单的 node.js 服务器和一些在其上运行的应用程序，它应该连接到 Oracle 数据库。出于这个原因，我决定使用node-oracledb驱动程序，但我在安装时遇到了一些问题。我按照Oracle 网页和github上的说明进行操作，但下面仍然出现错误。
我的环境配置：
- Windows 8.1 专业版 64 位
- node.js v6.4.0
- npm v3.10.3
- MS Visual Studio 2013 社区版
- Python v2.7.12
- Oracle Instant Client (基础+ SDK) v12.1.0.2.0
Node、Python 和 Oracle Instant Client 文件夹包含在 PATH 变量中。OCI_LIB_DIR 和 OCI_INC_DIR 也是根据github指令设置的。
这是问题所在：当我执行 command 时npm install oracledb -g，出现以下错误：
> oracledb@1.11.0 install C:\Users\pr\AppData\Roaming\npm\node_modules\ora
cledb
> node-gyp rebuild
C:\Users\pr\AppData\Roaming\npm\node_modules\oracledb>if not defined npm_c
onfig_node_gyp (node "C:\Program Files\nodejs\node_modules\npm\bin\node-gyp-bin\
\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild ) else (node "" rebuild )

我真的不知道在哪里寻找解决方案。什么可能导致该错误？节点/oracle 客户端/python 之间是否存在任何已知的不兼容性？
还有一件事：github指令说：
确保正确设置 Microsoft Visual Studio 环境变量。使用 set PATH 并验证它是否包含您的 Visual Studio 路径。如果未设置，请使用 vcvars64.bat（如果使用 32 位二进制文件构建，则使用 vcvars.bat）设置环境。
应该设置哪些 VS 环境变量，哪些 VS 路径应该包含在 PATH 中？
