An error notification received from the command "jspm install jquery"

As I follow the tutorial on the jspm.io site, everything goes smoothly until I reach step 3. When I try to execute jspm install jquery, an error message pops up.

The error reads: warn Error on getOverride for jspm:github, retrying (2). ReferenceError: ui is not defined at c:\Projects\Project1\node_modules\jspm\node_modules\jspm-registry\registry.js:157:5

Here are some details of my setup:

  • NodeJS version: v0.12.0
  • NPM version: 2.5.1
  • JSPM version: 0.14.0
  • Operating system: Windows 8.1

If anyone has any insights on what might be causing this issue, please share!

Answer №1

It appears that the issue occurred during the creation of the local registry clone by jspm. Make sure you have Git installed and configured correctly as git on your system. If not, it could be a permissions problem.

Fortunately, this was just a logging error which has been rectified with a recent update to the registry. So, if you update jspm in the future, any potential errors should be easier to understand.

Answer №2

When I encountered a similar issue with jspm, the root cause was actually related to how nodejs child_process.exec was invoking the git command.

The problem lied in the way child_process.exec was executing:

C:\Windows\system32\cmd.exe /s /c "git clone --depth=1 github.com/jspm/registry.git .

It turned out that cmd.exe was automatically running commands set in the registry beforehand. In my scenario, this included a command that altered the working directory, thereby overriding the cwd value.

To address this, check your registry settings at:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun
  • HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun

If there is a command present to modify the working folder's drive, it could be causing the error mentioned above.

In addition:

If you set your working folder as c:\ and run the following nodejs code:

var exec = require('child_process').exec;
exec('dir', { cwd: 'C:/windows/fonts' }, function(error, stdout, stderr) {
    console.log('stdout: ' + stdout);
});

If the contents of the fonts folder are not displayed, the issue may be linked to child_process.exec in node.
