The installation script for Phalcon is bash, the first line is #!/bin/bash[LF] , which means to look for this interpreter when executing directly (or sudo) /bin/bash .

If, for reasons like git cloning, the file line break unexpectedly changed [CR][LF] to the Windows style ...
Then, when the script executes, Sudo will still only remove the Unix line break [LF] , and then try to find /bin/bash[CR] the file as an interpreter, which of course is impossible to exist.

Use this command to check whether the first line of the file CR(0x0D) LF(0x0A) ends with:
cat install | head -n 1 | od -t x1

(If the reason is wrong, please find another point of failure)

In fact, you look at the first line of the install file and you know it.
#!/path/to/somewhere
This file doesn't exist, does it?

cat -A install
