我试图运行一个具有/**
* Handles the HTTP <code>GET</code> method.
*
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Handles the HTTP <code>POST</code> method.
*
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Notifies user of an error in the java code
*
* @param e Exception generated
* @return HTML as String
*/
private String returnError(Exception e) {
e.printStackTrace();
String returnString = "<html><body><h1>" + e.getMessage() + "</h1></body></html>";
return returnString;
}
依赖关系的烧瓶应用程序。没有安装python-devel,就无法安装pandas。所以首先我需要根据这个帖子安装gcc-c ++和python devel:'gcc' failed during pandas build on AWS Elastic Beanstalk
现在,我的pandas
看起来像是:
.elasticbeanstalk/config.yml
但是在成功branch-defaults:
default:
environment: flask-env
group_suffix: null
global:
application_name: flask-sample-app
branch: null
default_ec2_keyname: flask-sample-app
default_platform: Python 3.4
default_region: eu-west-1
include_git_submodules: true
instance_profile: null
platform_name: null
platform_version: null
profile: null
repository: null
sc: null
workspace_type: Application
packages:
yum:
gcc-c++: []
python-devel: []
命令后,我通过eb deploy
连接到它,看到它没有安装。我的config.yml是否正确?
答案 0 :(得分:0)
Pandas和NumPy似乎无论你采取什么方式部署某些东西都会给你带来最多麻烦。我自己还没有使用过弹性beanstalk,但直接在服务器和docker上完成了。
可以看到你所拥有的和对我有用的一个区别。根据{{3}}
,我认为你需要gcc和g ++所以也许在你的最后几行之前添加一行:
packages:
yum:
gcc: []
gcc-c++: []
python-devel: []
我只是翻译其他地区的工作。

当我在.ebextensions
而不是.elasticbeanstalk
创建yaml文件时,它有效。我只是将yaml文件放在错误的目录下。
.elasticbeanstalk / pandas.yml:
packages:
yum:
gcc-c++: []
python3?-devel.x*: []
我在尝试安装python-devel: []
时遇到错误:
实例上的命令失败。返回码:1输出:Yum没有可用于安装的python-devel
因此,在我的情况下,正确的devel包名称是'python27-devel.x86_64'或'python35-devel.x86_64'
