No such file or directory: 'virtualenv' when doing pipsi install pew

Here's a shell session:

What am I or have I done wrong?

Hmm, chicken and egg if I try 2.7:

tweedledee:~ chris$ curl https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

I had a similar problem and there are many similar related issues reported. I believe they relate to release 0.9, which is the most recent release available, and is the version installed by the recommended installation procedure

curl https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | python

There hasn't been a new release for a long time, so I installed pipsi from the master and this fixed the issue (probably thanks to commit be4abc4). Try installing from master :-

# Download the pipsi installer script from github
$ curl -O https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py

# Read about the --src option in the help menu
$ python get-pipsi.py --help

# Run the installer script to get the master branch from github
$ python get-pipsi.py --src=git+https://github.com/mitsuhiko/pipsi.git#egg=pipsi

[cjw296]

Could anyone persuade @mitsuhiko to do a new release?

[jacobian]

I worked around this by creating ~/.local/vens/pipsi/package_info.json containing {"name": "pipsi", "version": "0.10.dev", "scripts": ["/Users/jacobkaplan-moss/.local/bin/pipsi"]}.

[jacobian]

Oops, I meant to leave that comment on #124.

In my case (ubuntu 17.10) solution provided by @buzzjmd had to have a modification. Instead of providing --src=git+https://github.com/mitsuhiko/pipsi.git#egg=pipsi I used --src=git+https://github.com/mitsuhiko/pipsi.git so, removed the egg info, and that helped!

[almartin1911]

I've experienced the same issue performing the recommended installation procedure on a fresh Ubuntu 18 (Bionic Beaver) installation. Here's what I've done to solve it:

1. Uninstall pipsi
   rm -rf ~/.local/bin ~/.local/venvs
2. Fresh install (thanks PyGObject team)
   curl https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | python3 - --src=git+https://github.com/mitsuhiko/pipsi.git\#egg=pipsi
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
3. Install pew (and pipenv)
   pipsi install pew
pipsi install pipenv

[cjw296]

Doesn't look like this package is maintained anymore, I don't use it and @amartin1911 has provided a workaround, so closing.

I was also able to workaround this, by manually installing virtualenv in the environment of the base python pipsi uses:

$ curl https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | python3
$ pip3 install virtualenv

[bbrendon]

Failed out of the gate.
