npm包已经安装在cloudbees上的问题

Question

I am running Cloudbees with the following pre-build script config :

# install nodejs, if using cloudbees
curl -s -o use-node https://repository-cloudbees.forge.cloudbees.com/distributions/ci-addons/node/use-node
NODE_VERSION=0.11.1 source ./use-node

# install phantomjs, karma
npm cache clean
[ -d node_modules/phantomjs ] || npm install phantomjs
[ -d node_modules/karma ] || npm install karma
[ -d node_modules/karma-junit-reporter ] || npm install  karma-junit-reporter
[ -d node_modules/karma-phantomjs-launcher ] || npm install  karma-phantomjs-launcher

[ -d $HOME/bin ] || mkdir $HOME/bin
[ -f $HOME/bin/karma ] || ln -s /scratch/jenkins/addons/node/$node_name/bin/karma $HOME/bin/karma
[ -f $HOME/bin/node ] || ln -s /scratch/jenkins/addons/node/$node_name/bin/node $HOME/bin/node

Here is the error I get :

What strikes me is that the very same config used to work fine before my cloudbees was unprovisioned. Can anyone please help?

Answer 1

I'm not sure why this changed behavior, but you can fix you script with a simple:

test -L /home/jenkins/bin/karma || ln -s /scratch/jenkins/addons/node/node-0.11.1-x86_64/bin/karma /home/jenkins/bin/karma

Answer 2

I just set up the same thing in my environment.

I used -L rather than -f to test existence -- since I'm looking for a symlink.

I also noticed that the symlink path suggested in the blog post was incorrect. See correction below.

[ -L $HOME/bin/karma ] || ln -s /scratch/jenkins/addons/node/$node_name/lib/node_modules/karma/bin/karma $HOME/bin/karma
