安装python-spidermonkey失败，因为没有找到nspr

Question

尝试在Mac OS上使用pip安装python-spidermonkey，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 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:

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

我试着安装nspr:

sudo port install nspr

，但没有任何区别，仍然是相同的错误。什么好主意吗?

Answer 1

最后我得到了这个固定由我自己下面的线程:

http://davisp.lighthouseapp.com/projects/26898/tickets/38 -问题-安装- - mac os x - 107

两个步骤:

1。将这些文件从spidermonkey中的Darwin-XXX文件夹移到spidermonkey/libjs中，以解决这个错误。

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

2。在文件中做如下更改:libjs/jsutil

来自:

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

:

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

Answer 2

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update js lib并删除tmp dir:

$ 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

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

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);

安装lib

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

Answer 3

我找到了一个在MacOS 10.9上安装的解决方案(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

这在我使用如下spidermonkey模块的python代码中工作得很好。希望对你有帮助。

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