Mark Sta AnaHere's a handy cheat sheet if you find yourself needing an exotic version of Ruby, Python, Node or Rust. Other version management tools are available for ruby, python and node, I just happen to like these ones.
| Action | Ruby | Python | Node | Rust |
|---|---|---|---|---|
| List available versions to install | rbenv install --list |
pyenv install --list |
nvm ls-remote |
n/a |
| Install specific version | rbenv install 2.5.1 |
pyenv install 3.6.6 |
nvm install v10.9.0 |
rustup use nightly-2018-08-01 |
| List locally installed versions | rbenv versions |
pyenv versions |
nvm ls |
rustup show |
| Pin a project to a version | rbenv local 2.5.1 |
pyenv local 3.6.6 |
echo v10.9.0 > .nvmrc ; nvm use |
rustup override nightly-2018-08-01 |
| Set global version | rbenv global 2.5.1 |
pyenv global 3.6.6 |
n/a | rustup default nightly-2018-08-01 |
Python virtual environments
This assumes you've pinned your project to a specific version of python.
# create an virtual environment
pyenv virtualenv thingy
# activate!
pyenv activate thingy
# do your thang!
pip install pylint black pytest
# exit virtual environment
pyenv deactivate
Rust components (standard libraries, RLS, clippy)
Components will install for the active toolchain (stable, nightly, beta)
To install RLS: rustup component add rls-preview rust-analysis rust-src
To install clippy: rustup component add clippy-preview
Rust docs
Did you know you always get an off-line copy of the Rust documentation (language reference, standard library and the Rust book) suite when you install a toolchain? To open it for the active toolchain: rustup doc
