无法在Mojave上安装任何版本的ruby-内部ranlib命令失败 [英] Cannot install any version of ruby on Mojave - internal ranlib command failed

问题描述

我知道与此有关的一些silimar问题，但找不到与我的问题相符的问题.

I know there are a few silimar issues to this one, but I cannot find one that matches my issue.

我无法使用rvm或rbenv安装任何版本的ruby.两者都导致相同的错误.例如，以下是安装ruby 2.5.3时的日志摘录:

I cannot install any version of ruby with either rvm nor rbenv. Both result in the same error. For example, here's an extract for the logs when installing ruby 2.5.3:

compiling loadpath.c
making srcs under enc
linking static-library libruby.2.5.3-static.a
make[1]: Nothing to be done for `srcs'.
generating transdb.h
/opt/local/bin/ranlib: object: libruby.2.5.3-static.a(dln.o) malformed object (unknown load command 1)
ar: internal ranlib command failed
make: *** [libruby.2.5.3-static.a] Error 1
make: *** Waiting for unfinished jobs....
transdb.h updated

问题似乎在这里:

/opt/local/bin/ranlib: object: libruby.2.5.3-static.a(dln.o) malformed object (unknown load command 1)
ar: internal ranlib command failed
make: *** [libruby.2.5.3-static.a] Error 1

我尝试过的

• 安装，重新安装，卸载rvm，rbenv.
• 更新，重新安装XCode.
• 删除，安装XCode命令行工具.

What I've tried

• Installing, reinstalling, uninstalling rvm, rbenv.
• Updating, reinstalling XCode.
• Deleting, installing, XCode command line tools.

是什么原因造成的?

gcc --version返回:

gcc --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/c++/4.2.1
Apple LLVM version 10.0.0 (clang-1000.10.44.4)
Target: x86_64-apple-darwin18.0.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

推荐答案

所以，我认为对此修复程序正在运行:

So, I think the fix to this was running:

$ sudo xcodebuild -runFirstLaunch

为什么?我不知道.我的怀疑是我试图在更新XCode之前构建ruby.但是，一旦我更新了XCode，我怀疑还是以某种方式引用了错误/较旧的命令行工具.

Why? I'm not sure. My suspicion is I tried to build ruby before updating XCode. But once I had updated XCode I suspect the wrong/older command line tool was still being referenced somehow.

我不知道到底是什么解决了这个问题，但是我完全删除了XCode，而ruby仍然没有安装.

I don't know exactly what fixed this but I completely deleted XCode and ruby still didn't install.

然后我完全删除了命令行工具，而ruby仍然没有安装.

Then I completely deleted command line tools and ruby still didn't install.

然后，我只重新安装了没有XCode的命令行工具，而ruby仍然没有安装.

Then I reinstalled just the command line tools without XCode and ruby still didn't install.

然后我运行此runFirstLaunch命令并安装ruby.

Then I ran this runFirstLaunch command and ruby installed.
