Module Not Found Warnings #4

Closed sag8 closed 4 years ago

sag8 commented 4 years ago

I might be doing something wrong, but I get warnings for several modules not found when I run the command "npm run build" and I think as a result "npm run start" fails saying - "'env' is not recognized as an internal or external command,". (Complete error at the end.)

Warnings after "npm run build":

Have you tried running : "npm install" first ?

Have you tried running : "npm install" first ?

That was one quick reply. Thanks for the proactiveness and for building this tool.

Now, to answer the question - yes I did run npm install before running build command. After some googling, I found a way to save the missing packages displayed in the warning. Used the commands below:

But start is still giving me the same error.

(Also, I'm using Windows 10, if that makes any difference.)

AZn5ReD commented 4 years ago

Could you please pull the last version, I made some changes in the commands.

sag8 commented 4 years ago

Sure, I'll pull the latest version.

Before I do that, I'll like to let you know about the different ways I tried to fix this -

In both cases, I now get this error:

D:\GitHub\saplearninghub-pdf-downloader>npm run start

I tried find a solution to this program but have failed to find a proper answer. I can see .local-chromium folder in Puppeteer's directory. I tried running Chrome.exe from there and it's working properly.

Will pull the latest version and report back.

sag8 commented 4 years ago

Deleted the whole folder and pulled the whole project again. Now, I'm getting the Chromium error I mentioned above. "ENV is not a valid command" is resolved now. Thanks.

AZn5ReD commented 4 years ago

Could you please share de "config.json" file ? (Be sure to remove sensitive information first)

sag8 commented 4 years ago

Here you go -

Ok, I haven't tried on Windows. You need to double the backslash on each path : \\

And it worked! Downloaded one book successfully. I'll try downloading some more books. Thanks, mate.
