js-bson: Failed to load c++ bson extension, using pure JS version

[xpepermint]

I clicked on Fork, cloned the repo and I attached this module to my project. I get this error

js-bson: Failed to load c++ bson extension, using pure JS version

nodejs v0.11.13, latest osx. It looks that the problem is with the mongodb module (works with bson 0.2.15).

[lazdmx]

Same problem

[bazineta]

Same issue here; backing off to 3.8.15 resolves the issue on OSX under 0.11.13.

[vkarpov15]

Yeah I've noticed this too. Your code will still work, just you may have worse performance. I'll fix this for next version.

[xpepermint]

ok

[leohidalgo]

Same problem

[merqlove]

Same here. Will stay 3.8.15 till changes.

[jamlfy]

Ok.... Same problem!

[rubenstolk]

Any update on this?

[grandimk]

I had the same problem (mongoose 3.8.19 and node 0.10.33). I've just resolve it after noticing that npm install (and npm update) compile the Debug version of bson but index.js (placed in node_modules/mongoose/node_modules/mongodb/node_modules/bson/ext/index.js in my case) require the Release version. As you can see in this section of the code:

try {
    // Load the precompiled win32 binary
    if(process.platform == "win32" && process.arch == "x64") {
      bson = require('./win32/x64/bson');  
    } else if(process.platform == "win32" && process.arch == "ia32") {
      bson = require('./win32/ia32/bson');  
    } else {
      bson = require('../build/Release/bson');  
    }   
} catch(err) {
    // Attempt to load the release bson version
    try {
        bson = require('../build/Release/bson');
    } catch (err) {
        console.error("js-bson: Failed to load c++ bson extension, using pure JS version");
        bson = require('../lib/bson/bson');
    }
}

I went inside the build directory and simply compile bson with the following command

make BUILDTYPE=Release all

Somewhere in the repository it has been changed from Release to Debug, but I didn't search into it.

@Gas3 what version of npm are you using and what platform are you running this on? This really shouldn't be happening in stable node 0.10.x.

Also, I've managed to repro this - looks like a clean npm install with npm 2.0.0 (the version that comes with node 0.11.14) and node 0.11.14 makes this work fine. That is, rm -rf node_modules && npm install. Can y'all check if this helps?

[grandimk]

npm 2.1.7 on Os X 10.9.5

[vkarpov15]

Can you try a clean npm install - kill off node_modules and then npm install? This really sounds like an issue of changing versions of node without rebuilding js-bson.

[brunowego]

+1

[vkarpov15]

@brunobatista try rm -rf on your node_modules and do a clean npm install.

[Tyvain]

Same problem:
node version: v0.10.35
npm version: 2.1.18

[fsanzv]

Same problem here:
OS: Arch Linux
Node version: v0.10.35
npm version: 2.1.18
Mongoose version: 3.8.21

Tried 'rm -rf node_modules; npm cache clean; npm install' with no luck.
Tried also with Mongoose version 3.8.15 with same results.

[Jokero]

Same issue was on Ubuntu 14.04. My steps:

1. Updated npm to 2.1.18 from 1.3
2. npm cache clean
3. rm -rf node_modules
4. npm i
   It works!

But I see error on Windows 8.1. This "require" throws error:

bson = require('./win32/ia32/bson'); 

The specified procedure could not be found.
C:\Users\d.kiriliuk\Projects\vozovoz\node_modules\mongoose\node_modules\mongodb\node_modules\bson\ext\win32\ia32\bson.node

File bson.node exists

I'm getting the same error with Node v4.2.4, Mongo v2.6.11, OSX 10.11.2

When I run my app I get:

js-bson: Failed to load c++ bson extension, using pure JS version

I wonder if this is an OSX issue because I don't have any problems on Linux. Could this have something to do with the gcc, the default Clang compiler installed by XCode.

@vkarpov15 is right, update mongoose to 4.4.5 fix this problem

[jwerre]

@vkarpov15, Am I correct in assuming this issue is caused by running newer version of Mongoose with older versions of MongoDB — version 2.X for instance?

[vkarpov15]

No, the mongodb version has nothing to do with it.

[nityanarayan44]

[FIXED]

I also had this problem

---

OS: Windows 10
node: v4.2.3
npm: 2.14.7

---

i just simply set the python path

npm config set python python2.7

and reinstall the mongoose

npm install mongoose

---

and it worked.

[lutaoact]

@nityanarayan44 It worked for me

[lutaoact]

@mgol
I use OSX 10.10.5, node 4.4.2, npm 2.15.0, keystone 0.3.17

I went to node_modules/keystone/package.json, and remove mongoose from dependencies, then

npm config set python python2.7
npm install mongoose

this worked for me:

[Joselarcu]

Also worked for me the @nityanarayan44 solution

[sunfeng90]

Same problem.My version is node 2.15, platform Centos

[mgol]

There's no such version of Node as 2.15 so I think you mean io.js. And
io.js has been unsupported by upstream for a long time, upgrade to Node 4
or 6 ASAP.

Michał Gołębiowski

[sunfeng90]

@arefm Thx,it worked for me about updating the version 3.8.23.What's more,solveing another problem: length is undefined and so on.

[mnpenner]

@mgol He was talking about npm. The latest version of npm2 is 2.15.4.

[jwerre]

@mnpenner I believe its 3.8.8

[mnpenner]

@jwerre I said npm2. Some of us are stuck on npm 2 because 3 has a whole host of different problems.

[sunfeng90]

@mgol Sorry, the npm version is 2.15, not the node.

[sunfeng90]

@mnpenner Yes,you are a smart man!

[theladyjaye]

When using with Keystone this is what worked for me to get past that error:

add the following to my package.json deps:

"mongoose": "~4.4.16",
"mongodb": "~2.1.18",
"keystone": "^0.3.19",

then

npm install

finally

rm -rf node_modules/keystone/node_modules/mongodb
rm -rf node_modules/keystone/node_modules/mongoose

Now I don't get the error.

[HughGrant]

@aventurella I hit the same rock when I am trying keystone today, thanks for your solution.

but now we get some extraneous errors and some missing errors, is this ok?

[albe-rosado]

@tomwang1013 updating mongoose solved the problem, but somehow my app is not connecting to the DB.....

[theothermattm]

In our case, the reason that the c++ version bson was not found was because we were behind a corporate proxy and something in the BSON build process needs to reach out to fetch files. When we looked in node_modules/bson/builderror.log, we saw an error like this:

gyp WARN install got an error, rolling back install
gyp ERR! configure error
gyp ERR! stack Error: connect ECONNREFUSED
gyp ERR! stack     at errnoException (net.js:904:11)
gyp ERR! stack     at Object.afterConnect [as oncomplete] (net.js:895:19)

Which suggested that the proxy might be the issue.

Sorry for reawakening comments on this, but I wanted to post this for anyone else that hits this in the future since this thread was very helpful in solving our issue.

[Yugloocamai]

@aventurella thanks for your fix, it worked! Makes me feel a little funny though.

[GST5555]

I have this issue on Windows 10, can't run a "basic" example either... is supposed that the installation files should provide all the stuff to run something, or at least have the instructions to do so...
This is fucking annoying!!!!! :@

[icoronadoarellano]

The solution of @lutaoact is for me the most indicated if you use Windows. I tried with it and it solves my issue.

[vkarpov15]

If you're running into this issue, you're using an extremely old version of Mongoose. Please upgrade to Mongoose >= 5 👍
