I am trying to kickstart a simple VS Code extension using Yeoman, on Windows 10 Pro.

I am facing the same kind of problem that is described here "Error code Trying to copy from a source that does not exist", however, my configuration is totally different (everything portable) and I suspect that even though the symptoms are the same, my problem has a completely different origin.

I am launching my Yeoman command from Cmder, which is a portable console emulator (https://cmder.net/) that already comes with Git in it.

In Cmder I first installed Yeoman and the VS Code Extension Generator, and this is what I got:

D:\Progs\Cmder (portable)
λ npm install -g yo generator-code
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated uuid@3.4.0: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

npm notice Changelog: https://github.com/npm/cli/releases/tag/v8.10.0
npm notice Run npm install -g npm@8.10.0 to update!
npm notice

Then I tried to create my project with Yeoman, and this is what I got:

D:\Progs\VS Code (portable)\data\extensions

Error code

Trying to copy from a source that does not exist: D:\Progs\Node.js (portable)\node_modules\generator-code\generators\app\templates\ext-command-js\vscode

It is probably important to mention that I am using a portable version of Node.js (and npm), located in "D:\Progs\Node.js (portable)", and of course I added this directory to my Path environment variable.

Thank you.

I had a similar error message:

Trying to copy from a source that does not exist: C:\Users\dorwi\AppData\Roaming\nvm\v16.16.0\node_modules\generator-code\generators\app\templates\ext-command-ts\.gitignore

In my case, solved it by just creating an empty .gitignore file in the indicated path

I also use a portable Node version. If you go to the source, there is no .gitignore file there ! You can download the .gitignore file from https://github.com/microsoft/vscode-generator-code/tree/main/generators/app/templates/ext-command-ts for example for the Typescript template .
