已解决：32 位 NodeJs 完全解决了我的问题。

Answer 2

This commands solve same problem

npm install -g npm
npm cache clean
npm update
npm install

Answer 3

I tried many different suggestions finding a solution. For reference: I'm working in Goorm online IDE.

In the end, simply reinstalling npm in the root directory did the trick. I ran:

sudo npm install npm -g

and afterwards I was able to install packages as normal again.

Answer 5

I was getting leaf signature err,so i solved it by: //first type this

npm config set strict-ssl false

//and then

npm config set NODE_TLS_REJECT_UNAUTHORIZED 0

and after that try to install the packages.

Answer 6

I guess you need to clear your cache and update your npm from the root of your nodejs installation folder.

To do that, Navigate to your, C:\Program Files\nodejs\npm directory and issue the below command,

npm cache clean

After than update your npm using the below command,

npm update

Hope this helps!

Answer 7

清理缓存也对我有用

Answer 8

In my case, I was cloning a GIT repo at work that other developers were using and building without issue. Tried all these solutions but the ultimate fix was downgrading my version of npm to an earlier version. Very simple, I know, but this line of code may just save you a day of debugging if your output is different than other devs on your team!

npm -v

Answer 9

If you are a windows user run cmd as administrator and then install packages. It worked for me while installing express via npm.
