NPM install issue

For some reason, I cannot install (npm i) other packages while this package is installed. I get the error below. I have to first npm un react-native-material-menu and then install the other package then I can install this back. Is this just me?

Environment

Environment: OS: Windows 10 Node: 8.4.0 Yarn: 0.19.1 npm: 5.4.2 Watchman: Not Found Xcode: N/A Android Studio: Version 2.3.0.0 AI-162.3764568

Packages: react: 16.0.0 react-native: 0.47.1
