Installing with TPM: '~/.tmux/plugins/tpm/tpm' returned 1

[ghost]

I'm using Tmux 2.0 on Ubuntu 14.04

I tried to install tmux-sidebar with TPM:

set -g @plugin 'tmux-plugins/tmux-sidebar'

However, when I tell TPM to install it's dependencies, it fails with the following error:

'~/.tmux/plugins/tpm/tpm' returned 1

If I remove tmux-sidebar from my .tmux.conf, it works just fine.

Greetings from the future! For me those and similar errors went away when i simply installed less on which the plugin relies.

#also: returned 127 comes up when specifying the plugin two times (i had tpm manage the plugins AND added it to the .tmux.conf, which is wrong)
