问题总结

我正在遵循一些设置说明，其中包含以下步骤：

ARCHFLAGS="-arch x86_64" gem install pg -v 1.2.3

字符串
一个问题似乎与我运行的MacBookPro与M1芯片有关，每this SO thread
预期的结果大概是成功安装的pg gem（版本1.2.3）
相反，我看到的错误，我认为是有关的不同文件路径之间使用的英特尔和苹果芯片。

型

我尝试过：

1.根据我上面链接的文章，我尝试了这个：

ARCHFLAGS="-arch $(uname -m)" gem install pg -v 1.2.3

型
我认为这是一个相当巧妙的即兴表演;唉，没有骰子
1.同样的事情，但没有插值
我考虑放弃ARCHFLAGS位，因为说到底，这不是简单地试图安装pg的1.2.3版本吗？

我的问题

• 在带有M1芯片的MacBookPro上使用ARCHFLAGS变量的正确、明确的命令是什么？*

或者更重要的是：

• 我是否需要对ARCHFLAGS变量大惊小怪？*

编辑1：

我找到了this solution to a similar issue并完成了以下步骤：

brew install libpq
export PATH="/opt/homebrew/opt/libpq/bin:$PATH
gem install pg

型
它安装成功了，但那是pg -v 1. 5. 3（如果我使用-v 1. 2. 3真的有关系吗？）
