Update install instructions for Bash and Zsh (#1920)
* Update install instructions for Bash and Zsh * Synchronize README.md with `pyenv init` * Add a ~/.bash_profile note * Concatenate shims activation into installation for brevity (Pyenv can't be used meaningfully without shims anyway) Otherwise, we'd need to duplicate all the ~/.profile shenanigans in both sections * Update based on feedback * Proofread

||||
2. **Define environment variable `PYENV_ROOT`** to point to the path where
|
||||
pyenv repo is cloned and add `$PYENV_ROOT/bin` to your `$PATH` for access
|
||||
to the `pyenv` command-line utility.
|
||||
2. **Configure your shell's environment for Pyenv**
|
||||
|
||||
**Note:** The below instructions for specific shells are designed for common shell setups.
|
||||
If you have an uncommon setup and they don't work for you,
|
||||
use the guidance text and the [Advanced Configuration](#advanced-configuration)
|
||||
section below to figure out what you need to do in your specific case.
|
||||
|
||||
1. **Adjust the session-wide environment for your account.** Define
|
||||
the `PYENV_ROOT` environment variable to point to the path where
|
||||
you cloned the Pyenv repo, add the `pyenv` command-line utility to your `PATH`,
|
||||
run the output of `pyenv init --path` to enable shims.
|
||||
|
||||
These commands need to be added into your shell startup files in such a way
|
||||
that _they are executed only once per session, by its login shell._
|
||||
This typically means they need to be added into a per-user shell-specific
|
||||
`~/.*profile` file, _and_ into `~/.profile`, too, so that they are also
|
||||
run by GUI managers (which typically act as a `sh` login shell).
|
||||
|
||||
**MacOS note:** If you installed Pyenv with Homebrew, you don't need
|
||||
to add the `PYENV_ROOT=` and `PATH=` lines.
|
||||
You also don't need to add commands into `~/.profile` if your shell doesn't use it.
|
||||
|
||||
- For **bash**:

|
||||
echo 'eval "$(pyenv init --path)"' >> ~/.profile
|
||||
~~~
|
||||
|
||||
- **If your `~/.profile` sources `~/.bashrc` (Debian, Ubuntu, Mint):**
|
||||
|
||||
Put these lines into `~/.profile` _before_ the part that sources `~/.bashrc`:
|
||||
~~~bash
|
||||
export PYENV_ROOT="$HOME/.pyenv"
|
||||
export PATH="$PYENV_ROOT/bin:$PATH"
|
||||
eval "$(pyenv init --path)"
|
||||
~~~
|
||||
|
||||
**Note:** If you have `~/.bash_profile`, make sure that it too executes the above-added commands,
|
||||
e.g. by copying them there or by `source`'ing `~/.profile`.
|
||||
|
||||
- For **Zsh**:
|
||||
|
||||
Same as for Bash above, but add the commands into both `~/.profile`
|
||||
and `~/.zprofile`.

||||

3. **Add `pyenv init` to your shell** to enable shims and autocompletion.

Please make sure `eval "$(pyenv init -)"` is placed toward the end of the shell

2. **Add `pyenv` into your shell** by running the output of `pyenv init -`
