ripgrep 12.1.1
-SIMD -AVX (compiled)
+SIMD +AVX (runtime)

How did you install ripgrep?

If you installed ripgrep with snap and are getting strange file permission or
file not found errors, then please do not file a bug. Instead, use one of the
Github binary releases.

cargo install ripgrep

What operating system are you using ripgrep on?

Replace this text with your operating system and version.

Linux 5.9.16-1-MANJARO #1 SMP PREEMPT Mon Dec 21 22:00:46 UTC 2020 x86_64 GNU/Linux

Describe your bug.

Give a high level description of the bug.

After I cargo install ripgrep and use rg -P xxx, it says PCRE2 is not available in this build of ripgrep, so how can I cargo install ripgrep with pcre2 supported?

What are the steps to reproduce the behavior?

If possible, please include both your search patterns and the corpus on which
you are searching. Unless the bug is very obvious, then it is unlikely that it
will be fixed if the ripgrep maintainers cannot reproduce it.

If the corpus is too big and you cannot decrease its size, file the bug anyway
and the ripgrep maintainers will help figure out next steps.

What is the actual behavior?

Show the command you ran and the actual output. Include the --debug flag in
your invocation of ripgrep.

If the output is large, put it in a gist: https://gist.github.com/

If the output is small, put it in code fences:

What is the expected behavior?

What do you think ripgrep should have done?

[BurntSushi]

As documented in the README, you need to pass --features pcre2 to any commands that compile ripgrep from source in order to enable PCRE2.

In other words, after cloning, instead of cargo build, use cargo install --path . --features pcre2.
