Problems with npm install after loading project files.

this has been an ongoing occurrence with EVERY project in the REACT series. I am finally asking the question.

What is going on? Here is my terminal output when executing npm install for this project. I have gotten similar out put for EVERY project in the series.

As you can probably tell I have been solving the problem by keying in

npm audit fix --force

I have learned that the --force option makes sure everything gets "fixed" rather than merely most things. And, as you can see, I am manually loading any dependencies that do not get loaded by npm install.

I haven't run into any problems doing this, but it is a work around. And, I don't really have a real grip on what is happening by doing the work around.

Does anyone have any idea why this is an ongoing problem and how I can perform a real fix?

So, as far as I can tell this error doesn't actually prevent create-react-app from being usable, but in the interest of us both understanding more I did a quick search and found this: https://github.com/facebook/create-react-app/issues/3588

Seems that depending on the version of Node you are using there may be precompiled dependencies missing. I initially saw similar errors to you installing this project, but then switched to Node version 8.15.0 as suggested in a comment from the linked issue. Using Node 8 resulted in fewer errors in the logs, but ultimately these "errors" for node-gyp seem like they can be safely ignored.

I think this is probably the correct answer. I am on Node 10.13.0, so it is likely the version discrepancy incurred because of the lag time from the course production to the time when I take it. I think my real question may have been. What is my exposure when I do the:

npm audit fix --force

because that seems to make it all go away, but at what price?

TL;DR: npm audit fix --force can fix security vulnerabilities but can also break your code by install incompatible versions of dependencies. Don't use it unless you know why you need it :P

I don't really have experience with using npm audit, but it appears to be a tool for identifying security vulnerabilities in dependencies. Take a look at this blog post from npm for more details.

If you run npm audit without the fix argument you will see a list potentially vulnerable dependencies. The node-gyp dependency is logging errors/warnings while being installed, but these warnings are not because of security vulnerabilities with the version of node-gyp, so npm audit is not relevant to node-gyp in this case.

The docs for npm audit say that npm audit fix --force could cause vulnerable dependencies to be installed with versions that do not match what is defined in the package.json file. This could introduce a breaking change by installing an incompatible version of the dependency that doesn't have the vulnerabilities that npm audit detected. I think manually updating vulnerable dependencies is the way npm audit is intended to be used.

For a learning project like this you don't need to be concerned with vulnerable dependencies unless you plan to build an application that needs to run in a production environment. It also doesn't fix anything related to the node-gyp installation. And finally, there is a risk of it installing an incompatible version of a dependency and breaking the code. With all that in mind, npm audit fix --force isn't something you should probably be using in this situation.

Have you tried updating your npm modules and dependencies?

That's where I get the errors, performing the npm install, which loads the npm modules specified in the package.json. So, I guess I am not understanding your question.

I was curious and tried with yarn. The same kind of errors installing node-gyp occurred, but the output was styled a little differently.

Erik:

Thanks for the input. I will be more judicious in using npm audit fix.
