I am using bower
$ bower -v
0.9.2
latest version of bower is 1.x.x https://github.com/bower/bower/releases
I run to update bower to the latest version
npm update -g bower
this does not help
I still have
$ bower -v
0.9.2
1) you have to clear npm cache and then update bower
sudo npm cache clean
npm update -g bower
2) If 1st solution does not help
try to remove and install it again
npm -g uninstall bower
npm -g install bower
check if it is still here
which bower
if it will show you something like
/usr/local/bin/bower
then
rm <path from previous command>
and after install it again
npm -g install bower
open new bash window and enjoy latest version of bower
same will help with other packages
There could be a lot of moving parts here. First you should try
npm cache clean
sudo npm cache clean
npm update -g bower
…which is –given all the moving parts– not very likely to work for you.
On Mac, using brew and nvm with some history, you would do something like this:
1. figure out where bower is now
$ which bower
/usr/local/share/npm/bin/bower
$ ls -hal /usr/local/share/npm/bin/bower
lrwxr-xr-x 1 iwein admin 35B Dec 15 2013 /usr/local/share/npm/bin/bower -> ../lib/node_modules/bower/bin/bower
$ ls -hal /usr/local/share/npm/lib/node_modules/bower/bin/bower
-rwxr-xr-x 1 iwein staff 3.3K Sep 17 2013 /usr/local/share/npm/lib/node_modules/bower/bin/bower
$ bower -v
1.2.8
$ rm -rf /usr/local/share/npm/lib/node_modules/bower
2. reinstall bower using npm
$ npm install -g bower
/Users/iwein/.nvm/v5.11.1/bin/bower -> /Users/iwein/.nvm/v5.11.1/lib/node_modules/bower/bin/bower
/Users/iwein/.nvm/v5.11.1/lib
└── bower@1.7.9
$ bower -v
bash: /usr/local/share/npm/bin/bower: No such file or directory
$ which bower
/Users/iwein/.nvm/v5.11.1/bin/bower
$ bower
bash: /usr/local/share/npm/bin/bower: No such file or directory
$ ls -hal ~/.nvm/v5.11.1/bin/bower
lrwxr-xr-x 1 iwein staff 35B Jun 1 11:53 /Users/iwein/.nvm/v5.11.1/bin/bower -> ../lib/node_modules/bower/bin/bower
3. open a new terminal
…or source your .profile or whatever. Check if you're using the same node version (implying a different nvm version if you don't)
$ which bower
/Users/iwein/.nvm/v0.10.24/bin/bower
$ bower -v
1.4.1
$ nvm use 5
Now using node v5.11.1
$ which bower
/Users/iwein/.nvm/v5.11.1/bin/bower
$ bower -v
1.7.9
And you're good.
Note that:
- you have to make sure you are installing in the right place, you may need multiple versions of bower, nvm, npm or node on your system for different projects…
- you need to restart the terminal to make sure the linking is done correctly.
Probably the bower update worked fine, it's just missing update environment var.
On my Ubuntu was something like:
ln -sf /usr/local/n/versions/node/6.2.0/bin/bower /usr/bin/bower
