Pub command is not found after installing dart-sdk

Question

I want to write a command line application on my Ubuntu machine but I encountered a problem when I was installing the dart sdk of dart 2 on linux mint 19.

After the installation I can't run the pub command from the terminal. I always get this error:

   Command 'pub' not found, did you mean:

  command 'puf' from deb puf
  command 'pdb' from deb python
  command 'publ' from deb atfs
  command 'pua' from deb pglistener
  command 'dub' from deb dub
  command 'pcb' from deb pcb-gtk
  command 'pcb' from deb pcb-lesstif
  command 'pudb' from deb python-pudb

Try: sudo apt install <deb name>

I already tried some path settings from the internet but none of them work or only temporarily.

How can I fix this?

Answer 1

As someone mentioned in a comment to an (outdated) answer, the nowadays (due to Dart being supplied / integrated with / in Flutter now) suggested correct use of pub is to be called via the flutter command:

`flutter pub` 

ie. to use gRPC / protobufs v3 w/ Dart / Flutter:

`flutter pub global activate protoc_plugin` 

Answer 2

Sometimes when you install dart, you may also have a problem where the dart command works but the pub command does not work, this is because dart is only present in the /usr/bin, to solve this simply make a symlink and to add pub command to this /usr/bin directory.

sudo ln -s /usr/lib/dart/bin/pub /usr/bin/pub 

Hope this helps

It's important to ensure that the dart SDK is in the PATH. You can easily test it by trying to use pub or dart.

One way to ensure it's in the PATH is by creating a .bashrc file in your user's folder.

Then add the following:

PATH=$PATH:/path/to/dart/installation/bin/folder export PATH
