问题
I installed nvm, n, using sudo and decided to test it out by downloading several versions of node on my system. When I tried to switch between the node versions I kept getting "Permissions denied." So I decided to sudo the command for switching between versions too. That's when all hell broke loose. I keep getting
dyld:bad external relocation length
I've tried to reboot my terminal with some hope that it would magically fix itself out. Alas, I was wrong.Thanks in Advance.
Update 1: I've tried to use npm to install yo and it gives me the same "dyld" prompt, along with the following:
Trace/BPT trap: 5
Essentially I can't use npm anymore.
回答1:
I had the same thing happen.
I was using a mac, so I downloaded the .pkg for the version of node I was interested in and re-installed it (which reinstalls npm at the same time).
Everything was back up and running after that.
回答2:
I had the same this morning because of n package via npm,
Node was installed via brew (without npm), so i removed it this way;
brew uninstall node
then reinstalled the newer version via n package
n lts
if this is not enough because of policy rules of your mac, try
sudo npm lts
this solved my problem and saved a big time from reinstalling all global node modules.
回答3:
Just use n reinstall node that you break in.
回答4:
i solved my problem wihout uninstalling the nodejs,just update the node version by n, and it works.
sudo n latest
