Ruby 缺少 SQLite3 OCRA 可执行文件 sqlite_native.so

Question

我正在尝试使用 OCRA 打包以下 ruby 脚本（我在 Windows 10，Ruby 2.6）：

require 'sqlite3'

puts SQLite3::VERSION

运行这在 cmd 中正常工作：

C:\Users\monday\Documents\projects\sqlite3_test>script.rb
1.4.2

当我按以下方式打包 script.rb 时：

ocra --gem-full=sqlite3 --dll sqlite3.dll script.rb --output script.exe --verbose

我已将 sqlite3.dll 和 sqlite3.def 添加到我的 PATH 并根据关于 SO 和 GitHub 的各种建议添加到 C:\Ruby26-x64\bin。

这是当我运行结果 script.exe:

时弹出的错误

C:\Users\monday\Documents\projects\sqlite3_test>script.exe

根据 OCRA 的输出判断，我确定 lib/ruby/gems/2.6.0/gems/sqlite3-1.4.2/lib/sqlite3/sqlite3_native.so 存在于临时文件夹中：

...

我错过了什么？

Answer 1

经过一番研究，我发现错误消息 The specified module could not be found. 表示该程序可能缺少所需的 DLL。现在 sqlite3_native.so 存在，我推测它是缺少 DLL 的程序。运行 dumpbin 给出了以下结果：

C:\Program Files (x86)\Microsoft Visual Studio19\Community>dumpbin /dependents C:\Ruby26-x64\lib\ruby\gems.6.0\gems\sqlite3-1.4.2\lib\sqlite3\sqlite3_native.so
Microsoft (R) COFF/PE Dumper Version 14.22.27905.0

Dump of file C:\Ruby26-x64\lib\ruby\gems.6.0\gems\sqlite3-1.4.2\lib\sqlite3\sqlite3_native.so

File Type: DLL

  Image has the following dependencies:

    x64-msvcrt-ruby260.dll
    KERNEL32.dll
    msvcrt.dll
    libsqlite3-0.dll

...

显然，libsqlite3-0.dll 从未被 OCRA 检测到，因此从未移动到临时文件夹的 bin/ 目录中。快速搜索显示 libsqlite3-0.dll 确实存在于我位于 C:\Ruby26-x64\msys64\mingw64\bin 的机器上。我将其移至 C:\Ruby26-x64\bin，并使用以下选项将其移至运行 OCRA：

ocra --dll libsqlite3-0.dll script.rb --output script.exe

后来，我意识到OCRA现在可以自己检测这个DLL了：

=== Adding ruby executable ruby.exe
=== Adding detected DLL C:/Ruby26-x64/bin/ruby_builtin_dlls/libgmp-10.dll
=== Adding detected DLL C:/Ruby26-x64/bin/ruby_builtin_dlls/libffi-6.dll
=== Adding detected DLL C:/Ruby26-x64/bin/libsqlite3-0.dll <<<< HERE!
=== Adding detected DLL C:/Ruby26-x64/bin/ruby_builtin_dlls/libgcc_s_seh-1.dll
=== Adding detected DLL C:/Ruby26-x64/bin/ruby_builtin_dlls/libwinpthread-1.dll
=== Adding detected DLL C:/Ruby26-x64/bin/ruby_builtin_dlls/zlib1.dll
=== Adding detected DLL C:/Ruby26-x64/bin/ruby_builtin_dlls/libssl-1_1-x64.dll
=== Adding detected DLL C:/Ruby26-x64/bin/ruby_builtin_dlls/libcrypto-1_1-x64.dll
=== Adding external manifest C:/Ruby26-x64/bin/ruby_builtin_dlls/ruby_builtin_dlls.manifest

所以，最后：

ocra script.rb --output script.exe

正常工作，不需要sqlite3.dll。

这似乎是一个非常通用的解决方案，因为我能够通过将所需的 DLL 添加到 Ruby 安装的 bin/ 文件夹，从 OCRA 打包的脚本中制作 puma 运行。
