"python3" is valid, as is "python2", but<br> "python" itself is not, unless you install a special-purpose package<br> python-is-python3. "apt show python-is-python3" says, in part<br> <br> Description: symlinks /usr/bin/python to python3<br> In Ubuntu, all python packages use explicit python3 or python2<br> interpreter and do not use unversioned /usr/bin/python at all. Some<br> third-party code is now predominantly python3 based, yet may use<br> /usr/bin/python.<br> .<br> This is a convenience package which ships a symlink to point<br> the /usr/bin/python interpreter at the current default python3. It may<br> improve compatibility with other modern systems, whilst breaking some<br> obsolete or 3rd-party software.<br> .<br> No packages may declare dependencies on this package.<br> <br> In this case, Music Blocks is third-party code.<br> <br> However, the exact failing command is not from Music Blocks. See line<br> 12 of your Gist. This command is not in Music Blocks repository. As<br> shown by "git grep http.server".<br> <br> So my guess is you have installed a version of npm or node that is<br> incompatible with Ubuntu 20.04's Python policy. We can't fix that.<br> <br> I was able to reproduce your problem using npm and node from Ubuntu<br> 20.04 package archives, and then fix it by editing packages.json to<br> use "python3 -m http.server 3000" instead.<br> <br> On Mon, Sep 28, 2020 at 10:20:26AM +0530, Shrey tripathi wrote:<br> > Hello,<br> > <br> > I didn't know whom to contact regarding this or where to post this, hence am<br> > putting this up here.<br> > <br> > I was following the steps to set up Music Blocks on my local system from [1]<br> > here.
