Ruby Gem push失败求助：执行gem push时报文件不存在错误

Hey there, I feel your frustration—spending a day stuck on an error after a successful gem build is no fun. Let’s walk through some targeted fixes to get your gem pushed:

• Double-check the gem file name and path
  The error says it can’t find the file, so start here. First, run ls (Linux/macOS) or dir (Windows) in your terminal to list files in your current directory. Make sure the exact filename you’re using in gem push [gemname].gem matches what gem build generated. For example, if your build output says Successfully built RubyGem\n Name: my_gem\n Version: 1.0.0\n File: my_gem-1.0.0.gem, you need to push my_gem-1.0.0.gem—not just my_gem.gem.

• Re-generate the gem file
  Sometimes gem build might seem to succeed but produce a corrupted or incomplete file. Re-run the build command explicitly with your gemspec file:
  gem build your_gem_name.gemspec
  Watch the output closely to confirm it finishes without warnings, then immediately run the gem push command on the exact file it just created (don’t rename or move it first).

• Use an absolute path for the gem file
  Relative path issues can sneak in if you’re not in the exact directory where the gem was built. Try pushing with the full absolute path to the file, like:
  gem push /Users/you/projects/my_gem/my_gem-1.0.0.gem (macOS/Linux)
  or
  gem push C:\Users\you\projects\my_gem\my_gem-1.0.0.gem (Windows)

• Verify file permissions
  On Unix-like systems, run ls -l [gemname].gem to check if your user has read access to the file. If permissions look off, you can fix them with chmod +r [gemname].gem. On Windows, right-click the gem file, go to Properties > Security, and ensure your user account has read permissions.

• Update your gem tooling
  Outdated gem versions can cause unexpected bugs. Update your gem system with:
  gem update --system
  Once updated, re-build and re-attempt the push.

If none of these work, sharing the exact output from your gem build command and the full gem push command you’re running would help narrow down the issue further.
