Jenkins无法安装npm软件包

Question

Something weird is happening with my Jenkins install.

------ 1 ------

Here, I have a two build steps, consisting of two shell scripts:

First: npm install jspm

Second: npm install browser-sync

What could cause these weird issues?

Also, jenkins does not report any errors in it's logs, but I found something in the work space, the npm debug log:

It's a weird error which I do NOT. understand.

I am thinking: - maybe jenkins has a weird timeout, when installing larger packages - maybe there is a size limitation for the packages - maybe there is something wrong with the internal builds of the packages

Any ideas?

Answer 1

What I did it try to do my front end build - npm install, etc - without Jenkins on my VPS.

To my surprise the error was the same, which got me googling. It turned out to be a problem with the swap file not being set. Sometimes it's because it is to small, so give it a big size.

Here is a link how to set it up:

After that, I could run npm, and Jenkins was able to do it alsoe.
