install.sh throws errors

[mataneja]

Thanks for the bug report!

Describe the bug

The shell PATH is unset because of the install script throwing errors while installing in a Ubuntu 16.04/18.04 LXD container env:

root@c16:~# curl https://get.wasmer.io -sSfL | sh
Installing Wasmer and WAPM!
sh: 258: [: verbose: unexpected operator

Successfully installed wasmer 0.6.0!
sh: 182: [: verbose: unexpected operator
root@c16:~# wasmer
bash: wasmer: command not found
root@c16:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
root@c16:~# echo "`wasmer -V` | `rustc -V` | `uname -m`"
bash: rustc: command not found
wasmer 0.6.0 |  | x86_64

Steps to reproduce

1. Install LXD
2. Launch a Ubuntu 16.04 or 18.04 container
3. Install wasmer
4. See error

Expected behavior

A clear install and the PATH variable setup appropriately so that I can start using wasmer/wapm immediately.

Actual behavior

The wasmer.sh script file is created:

root@c16:~# cat .wasmer/wasmer.sh 
# Wasmer config
export WASMER_DIR="/root/.wasmer"
export WASMER_CACHE_DIR="$WASMER_DIR/cache"
export PATH="$WASMER_DIR/bin:$WASMER_DIR/globals/wapm_packages/.bin:$PATH"

However, I need to explicitly source wasmer.sh in order to be able to use the appropriate cli cmds.

Additional context

N/A

Thanks for the report! I wasn't able to reproduce this, but I think I found a fix. Let me know if you still have the issue after #716 ships!

\e[2mNote: We've added the following to your /root/.profile
If you have a different profile please add the following:

# Wasmer
export WASMER_DIR="/root/.wasmer"
[ -s "$WASMER_DIR/wasmer.sh" ] && source "$WASMER_DIR/wasmer.sh"

> Successfully installed wasmer 0.6.0!
\e[2mwasmer & wapm will be available the next time you open the terminal.
\e[2mIf you want to have the commands available now please execute:
source /root/.wasmer/wasmer.sh

That did the trick. I wonder if its better to source automatically as part of the install script so that the cmds are available immediately?

Oh! Haven't thought of that, it's an interesting approach!

env config problem

where is the default install path, and why not config it to the $PATH
