HI @Sunanda_Samaddar_30067,

The main cause for this is user permission issue. Please check the below thread that I found :

Let me know if it helps.

HI Kanika, appreciate your tip. That part is done, however after npm rebuild this shows up.

Hi @Sunanda_Samaddar_30067,

Thanks for sharing this information.

Which version of node are you using right now?

I have 12.4.0 version. You can find yours by running node --version command from your command line.

Kanika

#5

node is at v10.16.3.

#6

Can you please upgrade it to the latest version?

Kanika

#7

Thanks for helping Kanika. I should point out that import is unsupported in v10.*, see here for more.

#8

Does that mean your application is working? :slight_smile:

#9

Unfortunately, no. I suppose there’s still some syntax problem with src/index.js.

#10

Hi @Sunanda_Samaddar_30067,

Please check if you have .babelrc file in your directory. Run ls .babelrc from mflix-js directory where all your files are present.

I don’t have .babelrc, what kind of config should I use?

#12

What happens when you run npm install ?

Hi @Sunanda_Samaddar_30067,

Sorry, it was in the Handouts from the course, please download it again: m220/mflix-js.zip.

Sometimes, when we copy/paste the unzipped files, hidden files starting with . does not get copy.
