Question: I've tried installing rxjs with "npm install rxjs" but it still can't find the module after installing. I've tried installing "npm install --save rxjs-compat" as well as reinstalling and uninstalling the modules, but it still doesn't work. Thanks a lot for the help in advance!

Here's the version I'm using from the package.json file:
""rxjs": "^7.4.0","

**UPDATE**

Tried all the answers but still no luck:

Here's the code for my tsconfig file (Don't know why I can't edit the original question anymore): pastebin.com/bsv51Dmz –

**UPDATE 2**
I tried installing the version 6.5 and the errors dissapear in visual studio, but I still get them on the console when doing ng serve. Same error, can not find the module. I also tried removing node-modules and doing npm i, but no luck neither, same error happening

**UPDATE 3 SOLUTION**
So what I did was basically I went to stackblitz to find some project that had the same dependencies I was trying to use and was working, and found out they had the dependency declared as "rxjs: latest" I put that declaration on my package.json and then it started working!

Answer: 
**Solution**

After searching in a Chinese forum, I find out that this is just a graphical misunderstanding. In fact, the file is NOT permanently deleted when "Enable Recycle Bin" is activated on NAS. It will be moved to #recycle directory on your shared folder, and you can access it through Synology DSM. So, you can delete any files in Windows on that SMB share without any worries about permanent lost. But in Windows, it always shows a warning panel of "permanent delete" when you do a removing action.

If you want to deactivate the warning panel of permanent delete in your Windows, you can go to your user foled in C:\Users\{username}, choose a system default folder, for example "Downloads". Right click on this folder, go to "Location" tab and change the location to your SMB share. In this case, the files you that you delete will be showed in Recycle Bin on your Windows desktop as usual.

From a windows point of view, every delete on a network share in permanent (not in windows recycle bin). It can't know that the NAS will do the move to its own recycle folder.
