Why does NPM install another version then specified?

Question

I worked on a project and pushed it to a bitbucket. After a needed format of my hdd I pulled the project back on my HDD. But when I do the npm install now it installs a different version then specified in the package.json package?

My package.json file

Output when npm finishes installing

Notice the react v15.5.4 in stead of the specified v15.3.2

Answer 1

NPM allows you to specify version with semantic versioning specification in which

"react": "^15.3.2",

means "every minor release of version 15"

Just remove the "^" symbol to install the version you need (or change to "~" if you want to accept patch releases)
