Error: Template, Router, Meteor, and Mongo are not defined and cannot be referenced

Currently in the process of updating Crowducate from Meteor 0.8 to version 1.0 by running the command "meteor update". You can find the branch for Meteor 1.0 here.

Encountered some challenges during the update, specifically with replacing the old iron-router with the new iron:router. As a result, both versions are currently installed and this needs to be rectified. The Meteor package file contains:

# Meteor packages used by this project, one per line.
#
# 'meteor add' and 'meteor remove' will edit this file for you,
# but you can also edit it by hand.

# Packages by Meteor
standard-app-packages
preserve-inputs
audit-argument-checks
spiderable
less
coffeescript
accounts-password
accounts-facebook
accounts-google
accounts-ui

# Packages by community
minimongoid
iron-router
iron:router
kaptron:minimongoid

# Packages by Manuel Schoebel

When running meteor, I encountered the following error:

At the end, another error popped up which states:

Exception in defer callback: TypeError: Cannot read property 'insert' of undefined

This has led to various components being undefined, including my local change from Meteor.Collection to Mongo.Collection. Currently, both remain undefined.

Appreciate any assistance with resolving these issues, Amir

Answer №1

When I encountered errors after installing Iron Router using meteorite, it was because the version installed was not compatible with Meteor 1.x.

$ mrt add iron-router

To fix this issue, I removed Iron Router using meteorite and installed it using meteor:

$ mrt remove iron-router
$ meteor add iron:router

As an extra precaution, I recommend running a reset before restarting:

$ meteor reset
$ meteor

Answer №2

Dealing with a similar issue, I attempted to follow the instructions provided by @Jason but faced a recurring problem:

error: unknown package in top-level dependencies: iron-router

My attempts to install iron:router were unsuccessful. Thankfully, after browsing through this thread, I was able to resolve the issue by removing iron-router from .meteor/packages. It appears that executing mrt remove iron-router does not completely eliminate all references to iron-router.

Answer №3

If you are encountering a 'template undefined' error,

try executing the meteor reset command and then starting the server with meteor

Important: Running meteor reset will reset your build and local mongodb data.

Update: This should resolve the error, but if not, consider fully uninstalling meteor from your system and reinstalling it.

The core installation of meteor may have become corrupted during an auto-update from version 0.8 to 1.0

To Uninstall meteor -

rm -rf ~/.meteor

rm -rf /usr/local/bin/meteor

To Install

curl https://install.meteor.com/ | sh

This will install the latest version of meteor, version 1.0

After installing, update your project by following these steps:

cd <your-project-directory>

meteor update --release 1.0.0
