@ -29,21 +29,21 @@ This can be achieved by setting multiple versions of Python, for example with
asdf global python 3.6.2 2.7.13
```
This feature is experimental but should be working well enough for most use cases. Incidentally, the first python version you install will claim `python`. With the above example:
Executables in the first version will take priority over the executables in the next one. Note that you can use an arbitrary number over versions, if needed.
With the above example, `python` will therefore use the `python` executable found in version 3.6.2.
However, as the `python2` does not exist in Python 3.6.2, `python2` will use the `python2` executable found in version 2.7.13.
```
python -V
Python 3.6.3
Python 3.6.2
python3 -V
Python 3.6.3
Python 3.6.2
python2 -V
Python 2.7.13
```
In some cases, you might want python2 and python3 to co-exist, but python needs to point at a specific python version. The order of python versions is what controls this.
## Pip installed modules and binaries
If you use pip to install a module like ipython that has a binaries. You will need to run `asdf reshim python` for the binary to be in your path.
