Python calls subprocess no such file or directory error

At first I thought there was no class library

But the corresponding class library is present.

And then we took a closer look to find out.

Cmd= "/usr/local/redis/bin/redis-cli-h" +sys.argv[1]+ "-P" +sys.argv[2]
Oproc = subprocess. Popen (CMD)

The command called by Popen is an array, and then writes its own string.

The use of a string

And Commands.getoutput's usage for granted.
