npm [email protected] not found

Question

I have this error below but I dont have this package on my projecto directly. Anyone else is experiencing the same error? The project compiles and run correctly on my local env and I only get this error when i'm uploading the code to my heroku server. Yesterday I hade the same error with [email protected] but I deleted node_modules folder, deleted package-lock.json and run npm install and everything worked.

Answer 1

you just need to remove the following lines of code from your following file

• package.lock.json

==> "flatmap-stream": "0.1.1"
and ==> "flatmap-stream": { "version": "0.1.1", "resolved": "https://registry.npmjs.org/flatmap-stream/-/flatmap-stream-0.1.1.tgz", "integrity": "sha512-lAq4tLbm3sidmdCN8G3ExaxH7cUCtP5mgDvrYowsx84dcYkJJ4I28N7gkxA6+YlSXzaGLJYIDEi9WGfXzMiXdw==" }

basically,node team has removed that module because it had some malicious code.
