ruby-on-rails - bson_ext gem 安装在 macOS 上失败

Question

我坚持使用 1.5.1 版本安装 bson_ext gem。我已经尝试了几乎所有我在网上找到的东西，但没有任何帮助。我尝试重新安装 ruby、rvm 等。

我在用：

虚拟机
macOS Catalina 10.15.6
红宝石 2.6.5

在捆绑安装之后，我得到了这样的日志：

An error occurred while installing bson_ext (1.5.1), and Bundler cannot continue.
Make sure that `gem install bson_ext -v '1.5.1' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  bson_ext

有人知道我还能尝试什么吗？此外，我可以说 bson_ext 与 1.9.1 等其他版本安装成功。但在这个项目中我必须使用 1.5.1。

我找到了一个更好的解决方案，当你安装 gem 时在最后添加这个

-- --with-cflags="-Wno-error=implicit-function-declaration"

这在 MacOS 11.2 上对我有用。

gem install bson_ext -v '1.5.1' --source 'https://rubygems.org/' -- --with-cflags="-Wno-error=implicit-function-declaration"

1.5.1 已经 9 岁了，所以没有理由相信它应该可以工作。而且，事实上，它也因同样的错误而失败（Big Sur / 2.7.1 和 2.8.0）。

话虽如此，如果您 100% 坚持这样做，并且没有其他选择，例如更换雇主和/或有前途的软件考古学职业可以依靠，请尝试以下操作：

转到错误消息中指示的文件夹，/Users/lukasz/.rvm/gems/ruby-2.6.5/gems/bson_ext-1.5.1 for inspection.

从那里，转到ext/cbson并编辑文件bson_buffer.h。

您需要在文件顶部附近插入一行：

/* A buffer */
typedef struct bson_buffer* bson_buffer_t;
/* A position in the buffer */
typedef int bson_buffer_position;

/***** THE FOLLOWING IS THE LINE YOU NEED TO INSERT ****/
int bson_buffer_get_max_size(bson_buffer_t buffer); 

 /* Allocate and return a new buffer.
 * Return NULL on allocation failure. */
bson_buffer_t bson_buffer_new(void);

make在该文件夹中运行。它应该只需要一些警告。

之后，您仍然需要安装它。检查gem help install过程的详细信息。这是遵循其说明：

@ in bson_ext-1.5.1 $ gem spec ../../cache/bson_ext-1.5.1.gem --ruby > ../../specifications/bson_ext-1.5.1.gemspec

而且，确实：

@ in bson_ext-1.5.1 $ gem list bson_ext
*** LOCAL GEMS ***
bson_ext (1.5.1)

请注意，这又是在“原始”文件夹中。

即使在那之后，仅仅做 requite 'bson_ext' 对我也不起作用，并且 require 'bson' 抱怨它丢失了。根据该错误消息，您可能会通过移动来成功——我想在这里非常具体——<em>something, somewhere。不保证这会真正起作用。可能不是。

安装 1.3.1 版本对我有用

你确定你需要那个版本的 gem 还是你的项目中默认需要的？如果没有，您可以在 Gemfile 中明确设置 gem 的最新/安装版本，例如：

gem list bson_ext                                                                         

*** LOCAL GEMS ***

bson_ext (1.12.5)

# Gemfile
source 'https://rubygems.org'

gem 'bcrypt'
gem 'bson_ext', '~> 1.12.5'

当默认情况下捆绑安装尝试安装 bson_ext -v '1.5.1' 时，这对我在 MacOS BigSur 下有效，并退出并出现如下错误：
