Installation with npm fails but npx works

Question

On windows on a command prompt with local admin rigths i tried

• npm install jasmine but it fails to install jasmine
• to my surprise npx jasmine init did work

See command output below. For other packages the error is the same

• npm i @redocly/cli fails
• but npx @redocly/cli lint path-to-root-file.yaml did work

Question

• What could be the cause? How to fix it?
• What other workarounds do exist?

Running npm install jasmine or any other package results in
