Question

我最近尝试使用Julia v0.2.1在OS X 10.6.8上安装IJulia。安装IPython后，我运行了Pkg.build("IJulia")并得到以下控制台错误：

julia> Pkg.build("IJulia")
INFO: Building Homebrew
INFO: Cloning brew from https://github.com/staticfloat/homebrew.git
Cloning into '/Users/peterrichter/.julia/v0.2/Homebrew/deps/usr'...
dyld: Library not loaded: /usr/lib/libcurl.4.dylib
  Referenced from: /Applications/Julia-0.2.1.app/Contents/Resources/julia/libexec/git-core/git-remote-https
  Reason: Incompatible library version: git-remote-https requires version 7.0.0 or later, but libcurl.4.dylib provides version 6.0.0
==============================[ ERROR: Homebrew ]===============================

at /Users/peterrichter/.julia/v0.2/Homebrew/src/Homebrew.jl:200
at /Users/peterrichter/.julia/v0.2/Homebrew/deps/build.jl:1

================================================================================

似乎抱怨旧版本的libcurl（？），但是当我在终端中运行curl -V时，它说我使用的是curl 7.19.7。同样，执行ipython --version表明我使用的是最新版本的IPython 2.0.0。我误读了错误信息吗？如果是这样，我应该采取什么措施来解决它？

除了上面粘贴的错误文本外，它还打印了以下内容：

Answer 1

看起来您没有安装C编译器，因此Pkg.add在某些IJulia的nettle依赖项上失败。

您的第一个错误依赖关系虽然看起来像是您的julia发行版的捆绑git实现与系统提供的库之间的链接冲突。

你可以确切地看到git app与otool使用的共享库。

otool -L /Applications/Julia-0.2.1.app/Contents/Resources/julia/libexec/git-core/git-remote-https

这应该列出git-remote-https二进制文件链接到的libcurl dylib的完整路径。

您可以将其与otool -L $(which curl)的输出进行比较，看看它们是否链接到同一个库。

您还可以在引用的库本身上运行otool -L以查看它们的版本。这至少应该告诉你冲突是什么。您可能需要升级julia发行版使用的git版本。但我不确定那里会涉及什么。我只是从源代码安装了julia，绕过了这个特殊的问题。

您可能会发现更容易做到这一点。

Answer 2

对我有用的东西可能对你有所帮助：使用最新的Anaconda免费python，从github下载windows32 exe文件并解压缩，启动julia.bat，然后在Julia命令窗口输入Pkg.add（“IJulia”），在另一个命令窗口中输入 ipython notebook --profile = julia并享受在默认浏览器（Chrome）中打开的网页！由于--profile = julia命令部分的语法，我遇到了麻烦。

Answer 3

我也使用macports而不是Homebrew。我似乎通过将〜/ .julia / v0.3 / Nettle / deps / build.jl中的第21,22行更改为：

来解决这个问题。

libdirs = String["$(julia_usrdir)/lib"; "/opt/local/lib"]
includedirs = String["$(julia_usrdir)/include"; "/opt/local/include"]

即。我添加了macports lib并明确地包含了dirs。

有人可以通知有关当局，欢呼。
