Please i need help on how to fix it.

@ElNuru247 thank you for your post. A little more information is requested. Use termux-info and help us figure out what might be happening. My second question to you is simple. Did you root your precious smartphone?

[ismailnurudeen]

Thanks for replying.
Here is the result from using termux-info
termux-info.txt

My android device isn't rooted.

@ElNuru247 This is very very good, and thanks for this information. Permission errors do arise. Why? That is a good question. Can you post some more details regarding the files we are discussing? Also, what exactly are you doing in Termux? I hope you are having a wonderful time with your computer in your cool smartphone. Use ls -al and let us know how the files and directories related to this permissions issue look. Use screenshots if you like. They are very helpful at times. To sum up:
A) file and directory information,
B) your input and output.
Both are requested also so we can continue this issue.

@ElNuru247 Could you write the output of running the below commands here:

ls -la $PREFIX/bin/create-react-app
head $PREFIX/bin/create-react-app

[ismailnurudeen]

@frornwall here are the outputs of the commands you asked me to run

first command
$ ls -la $PREFIX/bin/create-react-app lrwxrwxrwx 1 u0_a225 u0_a225 45 Dec 3 21:55 /data/data/com.termux/files/usr/bin/create-react-app -> ../lib/node_modules/create-react-app/index.js

second command
` $ head $PREFIX/bin/create-react-app

!/data/data/com.termux/files/usr/bin/env node`

@@ElNuru247 Thanks for sharing. Can you provide a couple of more clues for us by running these commands?

ls -al $PREFIX/lib/node_modules/create-react-app/index.js
ls -al $PREFIX/bin/node

Post the link to create-react-app so we can take a closer look at the source code too. Where did you download create-react-app from?

[wschenk]

I'm able to get this to work. I would install

$ pkg install termux-exec proot

restart termux to get the scripts running correctly (as documented here https://wiki.termux.com/wiki/Termux-exec ) and then

$ termux-chroot
$ npm install -g create-react-app
$ create-react-app testapp

You get an error at the end saying that it can't rename "gitignore" to ".gitignore" but everything seems to work fine otherwise.

[ismailnurudeen]

I followed the @Wschenk 's steps above and it still didn't work.
here is a screenshot of the result.

[wschenk]

Did you try the instructions here? https://wiki.termux.com/wiki/Termux-exec That might help.

Seems create-react-app is working. With the exception of failed linking of gitignore - Android does not allow hardlinks.

Closing.

[campbellgoe]

Why is this closed? How is that a solution? I cannot use create-react-app on Termux and have the same output as xeffyr.

[Grimler91]

@GCDeveloper android doesn't allow hardlinks so you need to patch create-react-app to use symlinks instead. We can't do anything about this on the termux side

[xeffyr]

It actually works, only hardlink for gitignore is not created. Thats enough to close the issue.
BTW, termux-chroot from proot package should fix hardlink problem.

[messithegoat]

@GCDeveloper
this https://stackoverflow.com/questions/54073889/why-termux-dont-permission-to-create-gitignore-file-in-create-react-app works, perfectly.

[campbellgoe]

@messithegoat Thanks a lot, that does work perfectly.

Hello users pleace help me can I install this at sdcard in com.termux/files

No, you can only use node in termux's private storage. You can't use node in sd card or internal storage.
