安装ejs@3.1.3时postinstall脚本执行失败求助

Hey there, let's work through this EJS install issue you're hitting! The error from the postinstall script (node --harmony ./postinstall.js exiting with status 1) is a common hiccup, and we've got a few solid fixes to try:

Possible Solutions to Try #

• Check your Node.js version first
  The --harmony flag was used to enable experimental ES features in older Node versions. EJS 3.1.3 requires Node.js >= 6.0.0, but newer Node releases (v16+) have deprecated or removed this flag. Run node -v to check your version:

  • If you're on Node <6: Upgrade to at least v6 (LTS versions like v14 or v16 are better for stability)
  • If you're on Node v16+: The --harmony flag isn't needed anymore, so we can skip the postinstall script entirely (see next step)

• Skip the postinstall script during installation
  This is often the fastest fix. The postinstall script for EJS 3.1.3 mostly handles documentation updates, which isn't critical for the package to work. Run this command instead:

  npm install ejs@3.1.3 --ignore-scripts
  

• Clear npm cache and reinstall
  Corrupted cache files can sometimes cause script execution failures. Clear the cache first, then try installing again:

  npm cache clean --force
  npm install ejs@3.1.3
  

• Try using Yarn instead of npm
  Yarn handles package scripts differently and might bypass the issue. If you have Yarn installed, run:

  yarn add ejs@3.1.3
  

• Manual install and postinstall execution
  If none of the above work, download the EJS@3.1.3 package directly, extract it into your node_modules/ejs folder, then run the postinstall script without the outdated --harmony flag:

  node ./node_modules/ejs/postinstall.js
  

Once you've tried these steps, EJS should install successfully and work as expected.
