如何在 macOS 上安装 Mono，以便 Mono 在终端中工作? [英] How to install Mono on macOS so mono works in terminal?

问题描述

我正在尝试在 Mac(OS X 版本 10.10.5)上运行 Mono 安装，虽然安装表明它已成功完成，但我无法从终端调用 mono.

I'm trying to get a Mono install running on a mac (OS X version 10.10.5), and while the install states that it's completed successfully, I'm not able to call mono from the terminal.

为了安装它，我以 root 身份运行了 uninstallMono.sh 以确保我们没有任何剩余的东西，然后运行 ​​MonoFramework-MDK-4.0.4.1.macos10.xamarin.x86.pkg.安装程序似乎成功完成，但尝试调用单声道返回

To install it, I ran uninstallMono.sh as root to ensure we didn't have any leftover cruft, then ran MonoFramework-MDK-4.0.4.1.macos10.xamarin.x86.pkg. The installer appeared to complete successfully, but an attempt to call mono returns

-bash:单声道:找不到命令

-bash: mono: command not found

似乎确实安装了单声道框架:

The mono framework does appear to be installed:

...但它不存在于 /usr/bin 中，并尝试使用 which mono 查找其可执行文件不返回任何内容.

...but it isn't present in /usr/bin and attempting to find its executable using which mono returns nothing.

推荐答案

更新(因为两年多后仍然有浏览量):

最新版本的 Mono (5.x) 安装过程会在 /etc/paths.d 中创建一个文件 (mono-commands)，其中包含以下路径:

Update (since this is still getting views two+ years later):

The latest versions of Mono (5.x) installation process creates a file (mono-commands) in /etc/paths.d that contains the path of:

/Library/Frameworks/Mono.framework/Versions/Current/Commands

所以 /usr/local/bin 不再使用了...

So /usr/local/bin is no longer used...

较新版本的 mono 符合El Capitan"要求，即不在 /usr/bin 中安装任何东西，因此现在使用 /usr/local/bin.我不确定从哪个 mono 4.x 版本开始...

Newer versions of mono comply to the "El Capitan" requirements of not installing anything into /usr/bin and thus now /usr/local/bin is used. I am not sure which mono 4.x release that started in...

但我会假设您的路径中没有/usr/local/bin(?)，请尝试:

But I would assume that you do not have /usr/local/bin in your path(?), try:

export PATH=/usr/local/bin:${PATH}
which mono
which mcs

就我而言，我安装了 4.2.0:

In my case, I have 4.2.0 installed:

$ which mono
/usr/local/bin/mono
$ which mcs
/usr/local/bin/mcs
$ mono --version
Mono JIT compiler version 4.2.0 (explicit/2701b19 Mon Aug 31 09:57:28 EDT 2015)

$ cat `which mcs`
#!/bin/sh
export PATH=$PATH:/Library/Frameworks/Mono.framework/Versions/4.2.0/bin
export PKG_CONFIG_PATH=/Library/Frameworks/Mono.framework/External/pkgconfig:/Library/Frameworks/Mono.framework/Versions/4.2.0/lib/pkgconfig:/Library/Frameworks/Mono.framework/Versions/4.2.0/share/pkgconfig:$PKG_CONFIG_PATH
