I was able to cargo install anu --version 1.0.0-alpha with no problems.

If I clone the anu repository, and fix up the missing newlines in the Cargo.toml files (see #11, #13, #15), I still get a number of errors when running cargo build. Here is an excerpt:

There are a number of repeats of the Try error. The first one is simple enough to fix, by adding the tempfile dependency to Cargo.toml. The others I haven’t figured out yet.

It looks like https://nest.anu.dev/anu/anu/changes/A7JTCA76CNLA3IODP32FEZM7SQKSMAGGGE3AJ3Z6ZIVDUC3AFUMQC was responsible for adding the usage of tempdir without adding it to Cargo.toml.

It looks like https://nest.anu.dev/anu/anu/changes/IPLPLAWCIWB75ZC3D6IAQIFFYYS4DNCTPHOAFMPQWB5SX2ORSG6QC added the ? operator to a number calls to libanu::pristine::sanakirja::Pristine::txn_begin, but without updating txn_begin to return a Result.

Hi! Thanks for reporting. This is fixed, apparently, feel free to reopen if not.
