Answer 1

Just had the same issue. Type:

$ npm install [URL]

with the URL right before the shasum check fails. After that run your install command again and everything should go on.

eg. for Cordova it was:

$ npm install https://registry.npmjs.org/npm/-/npm-1.3.19.tgz

The root cause of this is fixed. Please do not take the advice in this thread and hack your way around checksum errors, ever. If something has a busted checksum, it's not to be trusted. At best, it's broken; at worst, it's maliciously hacked. Either way, it's not a good sign, and the error is the system working.

Answer 3

As @isaacs says mostly it will mean a corrupt package. In my case that was not the issue. What it worked for me was:

First, try:

npm set registry https://registry.npmjs.org/

and re-install what you was trying to install

Another workaround, use the npm mirror:

npm set registry http://ec2-46-137-149-160.eu-west-1.compute.amazonaws.com

you can reset this later with

npm set registry https://registry.npmjs.org/

then use it normally:

npm install [...]

Answer 4

Just reinstall, sometimes due to network problem. Once any module pack is uncompleted, shasum error will be throw. Please reinstall until successes.
