Now, Whenever I want install a npm package I get the following error:

D:\\Sources\\DownloadCms\\Md         


        

Answer 1

If you downgrade to 5.3 and still get the same error in Windows like me.
After hours working with npm versions I found the following solution:

1. Download latest recommended version of nodejs, these days is node-v6.11.3-x64
2. Uninstall nodejs with it.
3. Go to C:\Users\{YourUsername}\AppData\Roaming folder and delete npm and npm-cache folders
4. Run installer of nodejs again and install it
5 Update npm to 5.3 with npm i -g npm@5.3 command line

Now you should use npm without any issues.

Answer 2

For me it worked in bash from git package try:

C:\Program Files\Git\bin\bash.exe

then:

npm install mds.angular.datetimepicker@latest

Answer 3

npm cache verify solved my issue. I was doing: ng new my-app and I faced similar error

I have node version: 10.16.0
npm v 6.9.0

Answer 4

It is an npm 5.4.0 issue https://github.com/npm/npm/issues/18287

Workarounds are

• downgrade to 5.3
• try running with --no-optional, i.e. npm install --no-optional

Answer 5

I fixed by downgrading npm from 5.4.0 to version 5.3

npm i -g npm@5.3

I Hope this helps for you

Answer 6

For windows,

1. Download latest recommended version of nodejs, these days is node-v6.11.3-x64
2. Uninstall nodejs with it.
3. Go to C:\Users\{YourUsername}\AppData\Roaming folder and delete npm and npm-cache folders
4. Run installer of nodejs again and install it
5. By default npm 3.10.10 should be installed along with node-v6.11.3-x64.
6. It worked for me with npm 3.10.10 but did not work with 5.3.X. Also it did not worked with higher versions of node (above node-v6.11.3-x64)
