修复npm全局软件包符号链接

Question

Recently upgraded to OSX Mavericks and had all my npm global module symlinks wiped out! Reinstalling npm got npm to work again.

Is there a way to have npm recursively go through /usr/local/lib/node_modules/ and create the symlinks in /usr/local/bin for each package? (yes, it is in my Path)

Is there a way to do this a single package at a time?

My Google-fu is failing me at the moment. I have over 40 packages and I would hate to have to reinstall all of them or manually create symlinks for all the bins!

OSX 10.9
npm 1.4.14
node 0.10.29

Answer 1

Run this to rebuild in place without reinstalling:

for i in "$(npm prefix -g)/lib/node_modules/"*; do
  sudo npm build -g "$i"
done

But, are you sure that the symlinks are broken, and not that it simply changed your PATH environment variable or something? What does npm bin -g output?

Answer 2

Well this way is easy but it will re-download stuff, but it will still probably be faster than trying to script a way to repair them in place without redownloading:

npm install -g $(ls /usr/local/lib/node_modules)

If you try to manually create the symlinks, you are almost certain to miss some and/or make so mistakes, so I would not recommend that.
