我在Flask和mod_wsgi中使用apache。当我在Flask脚本上导入scipy模块时出现此错误。

我该如何解决这个问题？

我想你正在使用像CentOS这样的支持SELinux的发行版。当您的应用使用mod_wsgi支持Apache时，您必须在应用可以访问它们之前将标签httpd_sys_script_exec_t设置为共享对象文件。

在下面的示例中，我将假设您的应用程序位于/var/www/myapp目录中，而{2.7} virtualenv位于/var/www/myapp/venv中，Numpy和Scipy也安装在该virtualenv中。

您可以使用semanage永久添加新的SELinux政策：

semanage fcontext -a -t httpd_sys_script_exec_t "/var/www/myapp/venv/lib/python2.7/site-packages(/.*)?"

然后您可以使用restorecon激活它们：

restorecon -R /var/www/myapp/venv/lib/python2.7/site-packages/

如果在virtualenv中安装了一个包含共享对象文件的新包，则必须再次运行restorecon命令（或重启）。

使用apache + mod_wsgi运行，导入错误：无法启用可执行堆栈，因为共享对象需要：权限被拒绝
