Node modules are looked up in global paths

[ModernWebService]

• VSCode Version: Version 1.31.0 (1.31.0)
• OS Version: MacOS Mojave

I had an update notification pop up which I did not realize it was going to run when I closed my editor and then re-opened it shortly after. Since the latest released up, all my extensions will not run and on start up i get "Extension host terminated unexpectedly."

No matter how many times I click restart extension host it continues showing the failed message.

To clarify when this happened to me I was using 1.30 and restarted VSCode got the prompt for the January Changes skimmed it and then started noticing that no plugins were working.

• Restarted a few times and got the screenshotted prompt above.
• Tried restarted my laptop and then getting back in vscode
• Checked if there was another update after to fix it
• Then decided to re-install vscode while using another editor/terminal to ssh into a server to deploy the project I was working on when this happened

Since the re-install I do believe all my extensions are working as expect and do not believe I removed any. Most of my extensions are Larave, PHP, 1 or 2 Python, couple RoR, and then some Node/angular.

Re-installed vscode and extensions appear to be working again. But this did break extensions on my old install

[tkhwang]

I've got the same problem with the latest vscode.
I'm not sure, but it seems that it is same as before.. that of @ModernWebService.

I just share it again.

@ModernWebService @tkhwang Does this reproduce if you disable all extensions? (Most likely you have an extension installed that is causing this). You can also look for the extension host log to see which extension was being loaded when the crash occured. (F1 > Developer: Show Logs... > Extension Host).

With this stable release, we have updated our Electron version and if you are using any extension that uses native node modules, it will stop working and could cause extension host crashes.

[tkhwang]

@alexandrudima , As I checked, the crash dosn't occur after uninstalling the following plugin as you said.

VS Code for Node.js - Development Pack
https://marketplace.visualstudio.com/items?itemName=nodesource.vscode-for-node-js-development-pack

You may reproduce after installing this plugin, I guess.

(update) Actually the above plugin consists of a lot of plugins. As I tested, the crash dosn't occur after installing each of them. The crash only occurs after installing the the plugin itself.

(update2) I found another plugin which crashes.

Having this problem after update.

Can any one help me out, or tell me how to downgrade vscode?

[JM-Mendez]

I was having problems with the Settings-Sync extension. I was able to get it working by uninstalling fs-extra and fs-events from my global node_modules.

[acwo]

My extensions broke too. Most of them. Like Project Manager and other important for me. Seems that they don't work on a new version of vscode. Not cool.

Edit:
Uninstalling version 1.31 and going back to version 1.30 works.
You can download 1.30 from https://code.visualstudio.com/updates/v1_30

👆 👆 👆

[ModernWebService]

For me I went straight to re-installing VSCode fresh and seems to have cleaned out whatever was causing my issue. I still have the same extensions as before I believe, since I have it setup for laravel Node and some Go development. However, my dev tools were throwing similar errors as screenshot above. It seems like it may have broke something that these plugins were listening on, was in the middle of deploying a long project when this happened so I did not have time to mess around with dissecting what the root cause was.

[ModernWebService]

@Ravi448 look at @acwo 's comment, has a link to 1.30 which is the previous version

[tamuratak]

The cause is that node.js called by a VSCode extension host process tries to load modules in /Users/username/node_modules if it cannot find modules in /Users/username/.vscode/extensions/.../node_modules for each extension. This is a default behavior of node.js. See Loading from node_modules Folders.

I think VSCode should clear some entries of module.paths on extension host processes to prevent this behavior.

To workaround this issue, I recommend moving /Users/username/node_modules to /Users/username/npm/node_modules.

[renarsvilnis]

For now, I just downloaded v1.32 version and disabled updates in settings.json.

Didn't have to reinstall the extensions

{
  "extensions.autoUpdate": false,
  "update.channel": "none"
}

thanks, disabled the Settings Sync extension ,my vscode was backed in business!

[shanalikhan]

I'm the author of Settings Sync.

Users has been reporting about extension host killed by Settings Sync.

We removed the chokidar dependency from Settings-Sync which caused this problem, by replacing the vscode file watcher api.
But later found in documentation that vscode File Watcher only works for the workspaces file change events.

Its only broken On Mac, but works on Windows and Linux.

My main concern is:
Why some extension should be able to kill vscode extension host itself?
It works in other OS other than Mac.

@alexandrudima whats your views about it?

[tamuratak]

@shanalikhan, see my comment #68024 (comment).

[hdiggens]

I was having a similar issue with Microsoft Remote-Shell.
tamuratak post with regards to the node_modules and the NODE_PATH, resolved my issue.

VS-Code version 1.38.1

[alexdima]

Here is a easier repro for the global paths:

• package.json:

{
    "publisher": "alex",
    "name": "68024",
    "version": "0.0.0",
    "engines": {
        "vscode": "^1.0.0"
    },
    "activationEvents": [
        "*"
    ],
    "main": "index.js",
    "dependencies": {
        "fast-plist": "^0.1.2"
    }
}

• index.js:

exports.activate = function (ctx) {
    const Module = require('module');
    console.log(Module._resolveLookupPaths('$$$test$$$', module));
}

Observe how 3 global lookup folders are present (the last 3):

0: "/Users/alex/.vscode-oss-dev/extensions/68024/node_modules"
1: "/Users/alex/.vscode-oss-dev/extensions/node_modules"
2: "/Users/alex/.vscode-oss-dev/node_modules"
3: "/Users/alex/node_modules"
4: "/Users/node_modules"
5: "/node_modules"
6: "/Users/alex/.node_modules"
7: "/Users/alex/.node_libraries"
8: "/Users/alex/src/vscode/.build/electron/Code - OSS.app/Contents/Frameworks/Code - OSS Helper (Renderer).app/Contents/lib/node"

With my proposed change, this gets reduced to:

0: "/Users/alex/.vscode-oss-dev/extensions/68024/node_modules"
1: "/Users/alex/.vscode-oss-dev/extensions/node_modules"
2: "/Users/alex/.vscode-oss-dev/node_modules"
3: "/Users/alex/node_modules"
4: "/Users/node_modules"
5: "/node_modules"
