Mac OS-未能安装python spidermonkey，因为找不到nspr

尝试在我的Mac OS上使用pip安装python spidermonkey时失败，因为它缺少nspr:

$ pip install python-spidermonkey
Downloading/unpacking python-spidermonkey
  Running setup.py egg_info for package python-spidermonkey
    Traceback (most recent call last):
      File "<string>", line 16, in <module>

      File "/Users/smin/ENV/build/python-spidermonkey/setup.py", line 143, in platform_config
        return nspr_config(config=config)
      File "/Users/smin/ENV/build/python-spidermonkey/setup.py", line 87, in nspr_config
        return pkg_config("nspr", config)
      File "/Users/smin/ENV/build/python-spidermonkey/setup.py", line 59, in pkg_config
        raise RuntimeError("No package configuration found for: %s" % pkg_name)
    RuntimeError: No package configuration found for: nspr

----------------------------------------
Command python setup.py egg_info failed with error code 1 in /Users/smin/ENV/build/python-spidermonkey

但这没什么区别，还是一样的错误。有什么想法吗？

最后我按照这里的思路自己解决了这个问题：

两个步骤：

1.将文件从spidermonkey内的Darwin XXX文件夹移动到spider monkey/libjs，以克服此错误

cd /home/smin/virt-ENV/build/python-spidermonkey/spidermonkey
mv Darwin-i386/* libjs/

2.在文件中进行以下更改：

libjs/jsutil

我找到了一个在MacOS 10.9上安装的解决方法（下面第三行）

$ brew install pkg-config
$ brew install nspr
$ cd /usr/local/lib/pkgconfig/  # IMPORTANT
$ ln -s nspr.pc ../../Cellar/nspr/4.10.8_1/lib/pkgconfig/nspr.pc

$ git clone git://github.com/davisp/python-spidermonkey.git
$ cd python-spidermonkey
$ cp spidermonkey/Linux-x86_64/* spidermonkey/libjs/
$ python setup.py build
$ python setup.py test  # test failed, but it's okay to ignore

$ sudo python setup.py install

这与我使用spidermonkey模块的python代码配合得很好，如下所示。希望这有帮助

rt = spidermonkey.Runtime()
cx = rt.new_context()
cx.execute(js)
cx.execute("...")

首先安装nspr并设置系统变量：

$ brew install pkg-config
$ brew install nspr
$ export ARCHFLAGS="-arch x86_64" 
$ export PKG_CONFIG_PATH=/path/to/pkgconfig ## e.g. /usr/local/lib/pkgconfig

现在获取最新版本的代码：

$ git clone git://github.com/davisp/python-spidermonkey.git

现在运行更新js libs并删除tmp目录：

$ update-libjs.sh
$ rm -r /path/to/tmp/in/spidermonkey/dir ## e.g. ./tmp

文件libjs/jsutil.h替换第76行 从

到

文件libjs/jsprf.c注释行644

//VARARGS_ASSIGN(nas[cn].ap, ap);

现在安装lib

$ python setup.py build
$ python setup.py test
$ python setup.py install 

$ update-libjs.sh
$ rm -r /path/to/tmp/in/spidermonkey/dir ## e.g. ./tmp

typedef int js_static_assert_line_##line[(condition) ? 1 : -1]

typedef int js_static_assert_line_##line[(condition) ? 1 : 0]

//VARARGS_ASSIGN(nas[cn].ap, ap);

$ python setup.py build
$ python setup.py test
$ python setup.py install
