My setup is zsh 5.0.5 in arch linux
I have set the PATH variable as below in .zshenv
typeset -U path
path=(~/bin $path)
DW=$HOME/Downloads
but it didn't work. print $PATH shows only
/usr/local/bin:/usr/bin:/usr/bin/vendor_perl:/usr/bin/core_perl
.zshenv was read, because I could see DW variable is set. Only PATH variable isn't set. And what I don't understand is, after rename the .zshenv to .zshrc, PATH variable just works as intended.
Need any special treatment setting environment variables in .zshenv?

The PATH environment variable is an important security control. It specifies the directories to be searched to find a command. The default systemwide PATH value is specified in the /etc/profile file, and each user normally has a PATH value in the user's $HOME/. profile file.
PATH is an environment variable where you tell your system to look for executables when you enter a command in the shell. You can inspect the value of the PATH variable by running the following. $ echo $PATH.
PATH is an environmental variable in Linux and other Unix-like operating systems that tells the shell which directories to search for executable files (i.e., ready-to-run programs) in response to commands issued by a user.
I just encountered this problem myself, and the real answer is that Zsh on Arch sources /etc/profile – which overwrites and exports PATH – after having sourced ~/.zshenv.
