On recent versions of rustup, it attempts to auto-install clippy, which isn't available for that particular nightly:

$ rustup toolchain install nightly-2019-08-05

error: component 'clippy' for target 'x86_64-apple-darwin' is unavailable for download for channel nightly-2019-08-05

Adding --force causes it to skip clippy:

$ rustup toolchain install nightly-2019-08-05 --force
