Breakpoints are not working with Xcode 6

There are many reasons for this.

Please check this:
http://stackoverflow.com/questions/64790/why-arent-my-breakpoints-working

In my case what worked for me is:
Click on the Xcode project-> Build Settings ->Build Options -> set "Debug Information Format" as "DWARF with dSYM File".

This is in Xcode 6.1

Removing node.js and npm from mac os x

1. Go to /usr/local/lib and delete any node and node_modules
2. Go to /usr/local/include and delete any node and node_modules directory
3. check your Home directory for any local or lib or include folders, and delete any node or node_modules from there
4. Go to /usr/local/bin and delete any node and npm executable.
5. If you have installed in any other custom directory, please remove that as well.

Use below command to remove recursively.

>sudo rm -rf node

>sudo rm -rf node_modules

rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,node*,man1/node*}

Pulling your co-worker forked remote branch

> git remote add coworker https://github.com/coworker/studiorepo.git
> git fetch coworker
> git checkout --track coworker/foo

This will setup a local branch foo, tracking the remote branch coworker/foo. So when your coworker has made some changes, you can easily pull them.


> git pull

> git checkout foo

This will pull the latest changes. This is especially required when you wanted to pull the code and review it directly without really disturbing own repo. This will avoid setting up one more repository as well.

Installing npm node_modules into custom location

> npm install --prefix <custom directory path>

Example:
> npm install  --prefix C:\MyInstallations

With this, node_modules will be created in C:\MyInstallations folder.

For reference, nice content from stack overflow.

TL;DR

You can do this by using the --prefix flag and the --global* flag.

pje@friendbear:~/foo $ npm install bower -g --prefix ./vendor/node_modules
bower@0.7.0 /Users/pje/foo/vendor/node_modules/bower

*Even though this is a "global" installation, installed bins won't be accessible through the command line unless ~/foo/vendor/node_modules exists in PATH.

TL;R

Every configurable attribute of npm can be set in any of six different places. In order of priority:

• Command-Line Flags: --prefix ./vendor/node_modules
• Environment Variables: NPM_CONFIG_PREFIX=./vendor/node_modules
• User Config File: $HOME/.npmrc or userconfig param
• Global Config File: $PREFIX/etc/npmrc or userconfig param
• Built-In Config File: path/to/npm/itself/npmrc
• Default Config: node_modules/npmconf/config-defs.js

By default, locally-installed packages go into ./node_modules. global ones go into the prefix config variable (/usr/local by default).

You can run npm config list to see your current config and npm config edit to change it.
