AWS弹性豆茎错误 我尝试使用Dejango的WebApp使用HealthBean BooST，但是在部署的过程中，我发现有一些错误，请检查日志文件。我搜索日志文件但不能理解错误，有人能帮助我理解正在发生的事情吗？ Logs: * The following required packages can not be built: * freetype ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-n5etdtzo/matplotlib/ 2017-04-18 02:06:43,611 ERROR Error installing dependencies: Command '/opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt' returned non-zero exit status 1 Traceback (most recent call last): File "/opt/elasticbeanstalk/hooks/appdeploy/pre/03deploy.py", line 22, in main install_dependencies() File "/opt/elasticbeanstalk/hooks/appdeploy/pre/03deploy.py", line 18, in install_dependencies check_call('%s install -r %s' % (os.path.join(APP_VIRTUAL_ENV, 'bin', 'pip'), requirements_file), shell=True) File "/usr/lib64/python2.7/subprocess.py", line 541, in check_call raise CalledProcessError(retcode, cmd) CalledProcessError: Command '/opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt' returned non-zero exit status 1 (ElasticBeanstalk::ExternalInvocationError) caused by: Requirement already satisfied: appdirs==1.4.3 in /opt/python/run/venv/lib/python3.4/site-packages (from -r /opt/python/ondeck/app/requirements.txt (line 1)) Requirement already satisfied: aws-requests-auth==0.3.0 in /opt/python/run/venv/lib/python3.4/site-packages (from -r /opt/python/ondeck/app/requirements.txt (line 2)) Collecting awscli==1.11.61 (from -r /opt/python/ondeck/app/requirements.txt (line 3)) Using cached awscli-1.11.61-py2.py3-none-any.whl Collecting awsebcli==3.10.0 (from -r /opt/python/ondeck/app/requirements.txt (line 4)) Using cached awsebcli-3.10.0.tar.gz Collecting backports.ssl-match-hostname==3.5.0.1 (from -r /opt/python/ondeck/app/requirements.txt (line 5)) Using cached backports.ssl_match_hostname-3.5.0.1.tar.gz Collecting bdist-mpkg==0.5.0 (from -r /opt/python/ondeck/app/requirements.txt (line 6)) Using cached bdist_mpkg-0.5.0.tar.gz Collecting blessed==1.14.1 (from -r /opt/python/ondeck/app/requirements.txt (line 7)) Using cached blessed-1.14.1-py2.py3-none-any.whl Requirement already satisfied: boto3==1.4.4 in /opt/python/run/venv/lib/python3.4/site-packages (from -r /opt/python/ondeck/app/requirements.txt (line 8)) Collecting botocore==1.5.24 (from -r /opt/python/ondeck/app/requirements.txt (line 9)) Using cached botocore-1.5.24-py2.py3-none-any.whl Collecting cement==2.8.2 (from -r /opt/python/ondeck/app/requirements.txt (line 10)) Using cached cement-2.8.2.tar.gz Collecting colorama==0.3.7 (from -r /opt/python/ondeck/app/requirements.txt (line 11)) Using cached colorama-0.3.7-py2.py3-none-any.whl Requirement already satisfied: Django==1.10.6 in /opt/python/run/venv/lib/python3.4/site-packages (from -r /opt/python/ondeck/app/requirements.txt (line 12)) Collecting django-extensions==1.7.7 (from -r /opt/python/ondeck/app/requirements.txt (line 13)) Using cached django_extensions-1.7.7-py2.py3-none-any.whl Collecting django-extensions-shell==1.7.4.1 (from -r /opt/python/ondeck/app/requirements.txt (line 14)) Using cached django_extensions_shell-1.7.4.1-py2.py3-none-any.whl Collecting docker-py==1.7.2 (from -r /opt/python/ondeck/app/requirements.txt (line 15)) Using cached docker-py-1.7.2.tar.gz Collecting dockerpty==0.4.1 (from -r /opt/python/ondeck/app/requirements.txt (line 16)) Using cached dockerpty-0.4.1.tar.gz Collecting docopt==0.6.2 (from -r /opt/python/ondeck/app/requirements.txt (line 17)) Using cached docopt-0.6.2.tar.gz Requirement already satisfied: docutils==0.13.1 in /opt/python/run/venv/lib/python3.4/site-packages (from -r /opt/python/ondeck/app/requirements.txt (line 18)) Collecting elasticsearch==5.2.0 (from -r /opt/python/ondeck/app/requirements.txt (line 19)) Using cached elasticsearch-5.2.0-py2.py3-none-any.whl Collecting futures==3.0.5 (from -r /opt/python/ondeck/app/requirements.txt (line 20)) Using cached futures-3.0.5.tar.gz Requirement already satisfied: jmespath==0.9.2 in /opt/python/run/venv/lib/python3.4/site-packages (from -r /opt/python/ondeck/app/requirements.txt (line 21)) Collecting macholib==1.5.1 (from -r /opt/python/ondeck/app/requirements.txt (line 22)) Using cached macholib-1.5.1.tar.gz Collecting matplotlib==1.3.1 (from -r /opt/python/ondeck/app/requirements.txt (line 23)) Using cached matplotlib-1.3.1.tar.gz Complete output from command python setup.py egg_info: ============================================================================ Edit setup.cfg to change the build options BUILDING MATPLOTLIB matplotlib: yes [1.3.1] python: yes [3.4.3 (default, Sep 1 2016, 23:33:38) [GCC 4.8.3 20140911 (Red Hat 4.8.3-9)]] platform: yes [linux] REQUIRED DEPENDENCIES AND EXTENSIONS numpy: yes [not found. pip may install it below.] dateutil: yes [using dateutil version 2.6.0] tornado: yes [tornado was not found.

我使用Pycharm进行开发，但使用pipfreeze命令生成这些需求

更新1：我删除了一些要求并成功部署了它，但在尝试从链接访问webapp时，我遇到服务器500错误。

Elastic Beanstalk正在尝试逐个安装您的requirements.txt项，但它会在“egg_info”处停止。以下是错误：

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-n5etdtzo/matplotlib/

我猜您没有在本地开发中使用虚拟环境。这就是为什么您会在requirements.txt中看到所有不必要的项目：

您有两个选择：

尝试在实例上手动安装（或删除）出错的实例（在每次部署失败后逐个安装）。为此，您必须直接连接到EC2，然后

pip安装

或者

sudo pip安装

它们。您可能需要重复该过程几次

（不能很快切换到这种方法）创建一个简单的virtualenv，选择真正需要的需求，然后再次尝试部署

要创建新环境：

cd my_app

virtualenv .

激活环境：

source bin/activate

创建新的requirement.txt

pip freeze > requirements.txt

只添加必要的项目，完成
