🐞 Gotcha -- This directory must not be in protected area of computer -- e.g., in Windows it should not be under "C:\Program Files", "C:\Windows", ...

Let us create test directory "C:\Work\NpmSanityTest".
Or on MAC/unix, "\Work\NpmSanityTest".

• Open console
• Navigate to "NpmSanityTest" directory

Our console should look similar to the one shown here

Let's write a file to be doubly sure we have write access.

Do the commands shown and make sure you see the file content "hello"

Let's run npm without any prompts as the simplest test.

Run the command shown.

The "-y" flag simply means that we accept the default for every npm prompt (we bypass prompts).

NOTE WELL -- our console should remain in the test dir "C:\Work\NpmSanityTest" for all of this work.

Do the "dir" command (or "ls" for MAC/unix).

We should see "package.json" in the listing.
