updating node.js and npm

I was following the document but get some error while updating. Hooking up my shell to use nvm source ~/nvm/nvm.sh giving me some error. the errors-

(django2) 15:52 ~ $ cd mysite/

You were in ~/mysite when you cloned the repo, so nvm is not in ~/nvm, it's in ~/mysite/nvm

You need to provide an argument which would point to a node package (look at the error message that you copied), in other words -- you need to tell npm what you want to be installed.

so if i want to install react what command should i use now?

deleted-user-11053816 | 11 posts | Aug. 18, 2021, 4:40 p.m. | permalink

As @pafk said, you need to specify what you want to install. So if you want to install an npm package called react, you would use:

npm install react --global

again same problem-

(django2) 15:32 ~/mysite $ source ~mysite/nvm/nvm.sh
bash: ~mysite/nvm/nvm.sh: No such file or directory
(django2) 15:32 ~/mysite $

You're missing a slash between the ~ and mysite.

Permission denied

(django2) 15:50 ~/mysite $ ~/mysite/nvm/nvm.sh
bash: /home/webclip/mysite/nvm/nvm.sh: Permission denied
(django2) 15:51 ~/mysite $

The story is, I update the node.js before, that time nvm commands was working but after one day when i try to install react with npm install react --global ,it says npm: command not found . So , I try to hook up the nvm with bash and the above problem occured.

Is nvm.sh executable?

What is the result of ls -l /home/webclip/mysite/nvm/nvm.sh

fjl | 4352 posts | PythonAnywhere staff | Aug. 22, 2021, 9 a.m. | permalink

It's not an executable -- if you consider it safe to be executed, run chmod +x <filename> which will make the file executable.

pafk | 2973 posts | PythonAnywhere staff | Aug. 23, 2021, 4:03 p.m. | permalink

which file? nvm.sh ?

deleted-user-5156315 | 115 posts | Aug. 23, 2021, 4:13 p.m. | permalink

Yes, the one you're trying to run.

pafk | 2973 posts | PythonAnywhere staff | Aug. 23, 2021, 4:19 p.m. | permalink

did with nvm.sh filenname

(django2) 13:50 ~/mysite $ chmod +x <nvm.sh>                                                                                              
bash: syntax error near unexpected token `newline'

this the error

deleted-user-5156315 | 115 posts | Aug. 23, 2021, 4:21 p.m. | permalink

Sorry, "<filename>" was a placeholder -- use file path without brackets ("<", ">").

pafk | 2973 posts | PythonAnywhere staff | Aug. 23, 2021, 4:28 p.m. | permalink

didn't get it correctly

(django2) 14:54 ~/mysite $ chmod +x --mysite/nvm/nvm.sh
chmod: unrecognized option '--mysite/nvm/nvm.sh'
Try 'chmod --help' for more information.

what i'm missing?

chmod +x nvm.sh is not working

deleted-user-11053816 | 11 posts | Aug. 24, 2021, 3:40 p.m. | permalink

You need to use the filename of the file that you're trying to chmod. From earlier messages, it looks like you have nvm.sh here /home/webclip/mysite/nvm/nvm.sh. So you want:

chmod +x /home/webclip/mysite/nvm/nvm.sh

Is it because of storage(currently 76% full)?

deleted-user-11053816 | 11 posts | Aug. 25, 2021, 2:54 p.m. | permalink

Yes, unfortunately. I just did some experimenting and it appears that React has grown bigger and the installation requires more than 500M available on a free account. It appears that you need at least a Hacker account to use React nowadays...

pafk | 2973 posts | PythonAnywhere staff | Aug. 25, 2021, 3:59 p.m. | permalink

ok thanks. what If i use of react cdn or angular or vue.js? which will be suitable in the diskspace of free account?

deleted-user-11053816 | 11 posts | Aug. 25, 2021, 4:26 p.m. | permalink

You need to experiment -- the JavaScript environment is rapidly changing (for example free account's disk space used to be enough for React).

pafk | 2973 posts | PythonAnywhere staff | Aug. 25, 2021, 4:31 p.m. | permalink

I just update nvm and node.js and installed restframework, corsheaders thats all... it takes 75%. Why so much space? What if we use react older version?

deleted-user-11053816 | 11 posts | Aug. 25, 2021, 5:06 p.m. | permalink

React uses a lot of javascript modules and probably also has multiple copies of the same modules. It may be smaller if you use an older version. However, it may be better if you did our javascript development locally and then just uploaded the compiled javascript, which would be significantly smaller.
