的Mac OS - 无法安装python-SpiderMonkey的，因为NSPR没有找到

Question

尝试安装使用在我的Mac OS点子上python-SpiderMonkey的，没有这样做，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 186, in <module> 
     **platform_config() 
     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 
    Complete output from command python setup.py egg_info: 
    Traceback (most recent call last): 

    File "<string>", line 16, in <module> 

    File "/Users/shengjiemin/work/Ceilo-ENV/build/python-spidermonkey/setup.py", line 186, in <module> 

    **platform_config() 

    File "/Users/smin/rmonkey/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 

然后我试图安装nspr：

sudo port install nspr 

但它没有任何区别，仍然是相同的错误。有任何想法吗？

Answer 1

最后我得到了这个固定由我按照这里的线程：

http://davisp.lighthouseapp.com/projects/26898/tickets/38-trouble-installing-on-mac-os-x-107

两个步骤：

1.移动从达尔文-XXX文件夹内的SpiderMonkey文件到蜘蛛猴/ libjs来解决这个错误。

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

2.Make文件在下面的变化：libjs/jsutil

从：

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

到：

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

Answer 2

我发现一种解决方法（第三下面线）在MacOS 10.9上安装。

$ 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 

这适用于我的Python代码，使用像下面的spidermonkey模块。希望这可以帮助。

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

Answer 3

首先安装NSPR和设定的系统变量：

$ 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 

现在得到的最新版本的代码：

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

现在运行更新的js库，并删除TMP目录：

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

文件libjs/jsu til.h从

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

到

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

文件libjs/jsprf.c注释行644

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

取代线76 现在安装的lib

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