bash：conda：在Raspberry Pi上安装Miniconda后找不到命令

Question

I followed the instructions here to install Miniconda on my Raspberry Pi. The install script ran fine but I missed the step about changing the default installation directory. Is that a big problem? I updated .bashrc with export PATH="/root/miniconda3/bin:$PATH" and rebooted but I still get:

bash: conda: command not found

What should I do?

Debian version: 9.1 Raspberry Pi 2, ARMv7 Processor rev 5 (v7l)

Update:

So, since no-one answered I removed all the installed files at /root/miniconda3 and re-ran the install script, this time entering the following when prompted:

/home/pi/miniconda3

That seems to have solved the problem (although now I have a new problem).

Now when I try to do conda update conda I get:

Fetching package metadata: ....

Package plan for installation in environment /home/pi/miniconda3:

Have you tried with root privileges? ie. sudo conda update conda
