"conda activate" behavior changed after conda 4.5

[qingpeng]

I got the notification as below, which is something new to conda 4.5. But this has not been reflected in the documentation.

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If your shell is Bash or a Bourne variant, enable conda for the current user with

$ echo ". /global/homes/q/qingpeng/anaconda3/etc/profile.d/conda.sh" >> ~/.bashrc

or, for all users, enable conda with

$ sudo ln -s /global/homes/q/qingpeng/anaconda3/etc/profile.d/conda.sh /etc/profile.d/conda.sh

The options above will permanently enable the 'conda' command, but they do NOT
put conda's base (root) environment on PATH. To do so, run

$ conda activate

in your terminal, or to put the base environment on PATH permanently, run

$ echo "conda activate" >> ~/.bashrc

Previous to conda 4.4, the recommended way to activate conda was to modify PATH in
your ~/.bashrc file. You should manually remove the line that looks like

export PATH="/global/homes/q/qingpeng/anaconda3/bin:$PATH"

^^^ The above line should NO LONGER be in your ~/.bashrc file! ^^^

Took me a while to find something official in the changelogs. Here it is:

https://github.com/conda/conda/blob/master/CHANGELOG.md#440-2017-12-20

This is a MAJOR change and not well publicized.

@abalter Great find. The changelog explains the problem well.

I couldn't find references to the conda activate commands either. It seems like most of the docs reference the older source activate <ENV>.

I think one of the biggest issues is that the installation instructions still suggest modifying PATH.

e.g. https://github.com/conda/conda-docs/blob/master/docs/source/user-guide/install/macos.rst#installing-in-silent-mode

Don't want to post yet a new issue but the installer output is also still wrong, April 2019 meanwhile...:

installing: conda-4.5.12-py37_0 ...
installation finished.
Do you wish the installer to initialize Miniconda3
in your /data/root/.bashrc ? [yes|no]
[no] >>> no

You may wish to edit your /data/root/.bashrc to setup Miniconda3:

source /data/root/miniconda3/etc/profile.d/conda.sh

Thank you for installing Miniconda3!
[root@axc2_master ~]# source /data/root/miniconda3/etc/profile.d/conda.sh
[root@axc2_master ~]# which python
/usr/bin/python
[root@axc2_master ~]# WTF!?

[kellymarchisio]

@axgkl conda.sh should be run, not sourced. Try:
. /data/root/miniconda3/etc/profile.d/conda.sh
conda activate yourenvname
Then which python should return the correct thing. You'll know you've activated the environment if your env name appears in parenthesis before [root@axc2_master ~]
In the future, put . /data/root/miniconda3/etc/profile.d/conda.sh in your ~/.bashrc (assuming linux) so this'll run on startup.
