}

Trouble Shooting

When building your docs project, Set the env DEBUG=search-local:* to enable debug logs.

# In your docs project:
DEBUG=search-local:* yarn build

In case some specific errors occurred:

• Error: Cannot mix different versions of joi schemas:
  • Try using @easyops-cn/docusaurus-search-local >= v0.16.0 with Docusaurus >= v2.0.0-alpha.73
  • Try using @easyops-cn/docusaurus-search-local between v0.14.0 and v0.15.1 with Docusaurus between v2.0.0-alpha.68 and v2.0.0-alpha.72
  • Or try using @easyops-cn/docusaurus-search-local <= v0.13.1 with Docusaurus <= v2.0.0-alpha.66
• Error: Command failed with signal "SIGSEGV":
  • This is probably caused by a known issue introduced by nodejieba@2.5.2, if you enabled language of zh.
  • Try downgrading nodejieba to 2.4.2 and it will work again, see discussions in #47.
