What version of Bun is running?
1.2.14+6a363a38d
What platform is your computer?
Darwin 24.5.0 arm64 arm
What steps can reproduce the bug?
mkdir test && cd test
bun add -D --no-cache husky
bun rm husky
bun add -D husky
bun rm husky
bun add -D husky
What is the expected behavior?
bun i ... will be faster than bun i ... --no-cache
What do you see instead?
Here's the speed with no cache:
chao@MacBook-Air test % bun i @commitlint/cli @commitlint/config-conventional -D --no-cache
bun add v1.2.14 (6a363a38)
installed @commitlint/[email protected] with binaries:
- commitlint
installed @commitlint/[email protected]
101 packages installed [7.82s]
remove:
chao@MacBook-Air test % bun rm @commitlint/cli @commitlint/config-conventional
bun remove v1.2.14 (6a363a38)
- @commitlint/cli
- @commitlint/config-conventional
2 packages removed [2.00ms]
package.json has no dependencies! Deleted empty lockfile
since bun i --no-cache will not create cache, I run the following command to add cache:
chao@MacBook-Air test % bun i @commitlint/cli @commitlint/config-conventional -D
bun add v1.2.14 (6a363a38)
installed @commitlint/[email protected] with binaries:
- commitlint
installed @commitlint/[email protected]
2 packages installed [242.50s]
remove again:
chao@MacBook-Air test % bun rm @commitlint/cli @commitlint/config-conventional
bun remove v1.2.14 (6a363a38)
- @commitlint/cli
- @commitlint/config-conventional
2 packages removed [2.00ms]

install with cache:
chao@MacBook-Air test % bun i @commitlint/cli @commitlint/config-conventional -D
bun add v1.2.14 (6a363a38)
installed @commitlint/[email protected] with binaries:
- commitlint
installed @commitlint/[email protected]
2 packages installed [491.09s]
You can see that bun i with cache took much time than that with no cache.
Here's the table:
