As I was following through the tutorial on the same topic (https://geektnt.com/how-to-mount-digitalocean-space-on-centos-7.html), I successfully established and download with (git clone https://github.com/s3fs-fuse/s3fs-fuse.git)
but error command.

1)

[root@centos-s-1vcpu-1gb-sgp1-01 s3fs-fuse]# ./configure:
- onfigure: error: Package requirements (fuse >= 2.8.4 libcurl >= 7.0 libxml-2.0 >= 2.6 ) were not met:
- 
- No package 'fuse' found
- No package 'libcurl' found
- 
- Consider adjusting the PKG_CONFIG_PATH environment variable if you
- installed software in a non-standard prefix.
- 
- Alternatively, you may set the environment variables common_lib_checking_CFLAGS
- and common_lib_checking_LIBS to avoid the need to call pkg-config.
- See the pkg-config man page for more details.
