Error with jeprof Command: The first profile should be a remote form to use /pprof/symbol

The jeprof command is encountering an error: The first profile should be a remote form to use /pprof/symbol, as shown below:

Using local file 2.heap.
The first profile should be a remote form to use /pprof/symbol

This is because the command necessitates the original binary files of the program.

For Java projects, the following command can be used:

jeprof --show_bytes --gif /usr/bin/java --base=1.heap 2.heap > ./3.gif

For Go projects, the executable file after compilation is required:

jeprof --show_bytes --gif /usr/local/xxx/yyy/zzz --base=1.heap 2.heap > ./3.gif

Error: dot -Tgif: No such file or directory

Dropping nodes with <= 5107 B; edges with <= 1021 abs(B)
Can't exec "dot": No such file or directory at /usr/local/bin/jeprof line 2096.
| dot -Tgif: No such file or directory

This may be due to a missing dependency command, which is why it does not output a PDF. Instead, opt for text or image output.

jeprof --show_bytes --text /usr/local/xxx/yyy/zzz 2.heap

Output:
