在linux共享主机中的python wsgi应用程序中运行node/lessc

我试图在一个共享主机环境中以守护程序模式使用apache和mod_wsgi运行一个Odoo（openERP）实例，这意味着我没有超级用户权限

该应用程序需要较少的编译器才能正常工作，由于系统没有安装node/lessc，我为用户自定义安装了node，并将二进制文件添加到路径中。问题是apache正在为另一个用户运行，我无法让wsgi应用程序bash一个lessc命令

如何让node和lessc为我的用户工作：

export PATH=~/apps_wsgi/node/bin:$PATH

我的python版本是2.7.10，下面是一些更多的系统信息：

[admsolariza@web7695 ~]$ cat /proc/version

以下是我的wsgi脚本：

import sys, os

venv_path = '/home/admsolariza/apps_wsgi/odoo_env/lib/python2.7/site-packages'
if venv_path not in sys.path:
        sys.path.insert(0, venv_path)

project_path = '/home/admsolariza/apps_wsgi/odoo'
if project_path not in sys.path:
        sys.path.insert(0, project_path)

node_path = '/home/admsolariza/apps_wsgi/node/bin'
if node_path not in sys.path:
        sys.path.insert(0, node_path)

import commands
status, output = commands.getstatusoutput("lessc")
with open('apps_wsgi/log', 'w') as f:
        f.write(output)

import odoo

#----------------------------------------------------------
# Common
#----------------------------------------------------------
odoo.multi_process = True # Nah!

# Equivalent of --load command-line option
odoo.conf.server_wide_modules = ['web']
conf = odoo.tools.config

# Path to the OpenERP Addons repository (comma-separated for
# multiple locations)

conf['addons_path'] = os.path.join(project_path, 'addons')

# Optional database config if not using local socket
conf['db_name'] = 'foo'
conf['db_host'] = 'bar'
conf['db_user'] = 'foo'
#conf['db_port'] = 5432
conf['db_password'] = 'bar'

#----------------------------------------------------------
# Generic WSGI handlers application
#----------------------------------------------------------
application = odoo.service.wsgi_server.application

odoo.service.server.load_server_wide_modules()

sh: lessc: command not found

由wsgi脚本创建的日志文件的内容：

import sys, os

venv_path = '/home/admsolariza/apps_wsgi/odoo_env/lib/python2.7/site-packages'
if venv_path not in sys.path:
        sys.path.insert(0, venv_path)

project_path = '/home/admsolariza/apps_wsgi/odoo'
if project_path not in sys.path:
        sys.path.insert(0, project_path)

node_path = '/home/admsolariza/apps_wsgi/node/bin'
if node_path not in sys.path:
        sys.path.insert(0, node_path)

import commands
status, output = commands.getstatusoutput("lessc")
with open('apps_wsgi/log', 'w') as f:
        f.write(output)

import odoo

#----------------------------------------------------------

# Optional database config if not using local socket
conf['db_name'] = 'foo'
conf['db_host'] = 'bar'
conf['db_user'] = 'foo'
#conf['db_port'] = 5432
conf['db_password'] = 'bar'

#----------------------------------------------------------

application = odoo.service.wsgi_server.application

odoo.service.server.load_server_wide_modules()

sh: lessc: command not found

我所期望的是lessc命令被找到并正常工作。有什么想法吗？

如果

node\u path

是可执行路径，那么应该将其添加到

path

环境变量中，而不是

sys.path

。编辑

os.environ['PATH']

。工作起来很有魅力！！！非常感谢你。这个问题困扰了我好几个小时。我以为sys.path编辑了$path变量。
