Error while installing node-oracledb

问题

I have a simple node.js server and some app running on it, that should connect to Oracle database. For that reason I decided to use node-oracledb driver, but I'm having some problems with installation. I followed instructions on Oracle webpage and those on github, but I still get an error below.

My environment configuration:

Windows 8.1 Pro 64 bit
node.js v6.4.0
npm v3.10.3
MS Visual Studio 2013 Community edition
Python v2.7.12
Oracle Instant Client (basic + SDK) v12.1.0.2.0

Node, Python and Oracle Instant Client folders are included in PATH variable. OCI_LIB_DIR and OCI_INC_DIR are also set according to github instructions.

Here's the problem: when I execute command npm install oracledb -g, the following error occurs:

> 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

\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )  else (node "" rebuild )

I don't really know where to look at for a solution. What could cause that error? Are there any known incompatibilities between node/oracle client/python?

One more thing: github instructions say:

Make sure the Microsoft Visual Studio environment variables are set appropriately. Use set PATH and verify it contains your Visual Studio paths. If they are not set, use vcvars64.bat (or vcvars.bat if you building with 32-bit binaries) to set the environment.

Which VS environment variables should be set and which VS paths should be contained in PATH exactly?

回答1:

Modules like oracledb or node-oracledb needs compilations. Compilation requires software like C compiler, Python etc.

I was facing the same issue with oracldb module. follow below instructions and it works like charm.

回答2:

try updating npm to the latest version:

npm install -g npm

if it still doesn't work, try including your VS version like so:

npm install oracledb --msvs_version=2013
