virtualenv：无法访问lib：没有此类virtualenv或站点目录 [英] virtualenv: cannot access lib: No such virtualenv or site directory

问题描述

我正在使用Google Cloud Platform创建一个基于Django的http API，它使用了Google的云SQL API和机器学习API。

I am using Google Cloud Platform to create a Django based http API, which uses Google's cloud SQL API and Machine Learning API.

我制作了一个django-mysql应用程序在我的电脑上，并能够在本地主机上成功测试它。我想将此应用程序部署到Google Cloud。

I made a django-mysql app on my pc and is able to test it successfully on localhost. I want to deploy this app to Google Cloud.

以下是我的相关文件：
app.yaml：-

Following are my relevant files: app.yaml:-

runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /static
  static_dir: static/
- url: .*
  script: mysite.wsgi.application

libraries:
- name: MySQLdb
  version: 1.2.5
- name: numpy
  version: "1.6.1"


skip_files:
- ^(.*/)?- ^(.*/)?.*~$
- ^(.*/)?.*\.py[co]$
- ^(.*/)?.*/RCS/.*$
- ^(.*/)?\..*$
- ^env/.*$

appengine_config.py：-

from google.appengine.ext import vendor
import os
vendor.add(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib'))

我在api home上遇到500错误。 此处。我在仪表板上收到以下错误报告：-

I am getting a 500 error on api home. here. I am getting the following error report on my dashboard:-

Traceback (most recent call last):
  File "/base/data/home/runtimes/python27_experiment/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 240, in Handle

    vendor.add('lib')

    'No such virtualenv or site directory' % path)
ValueError: virtualenv: cannot access lib: No such virtualenv or site directory

最初 appengine_config.py 包含：-

from google.appengine.ext import vendor

vendor.add('lib')

根据建议 ，我将其更改为当前文件。

As suggested here, I changed it to the current file.

我使用 gcloud app deploy 部署我的项目。我不明白如何使用 gcloud_sql_proxy 进行部署。

I deploy my project using gcloud app deploy. I do not understand how to use gcloud_sql_proxy for deploying.

我肯定有 lib 文件夹与 app.yaml 位于同一目录中。我不知道我在做什么错。

I am for sure having a lib folder in same directory as app.yaml. I do not know what I am doing wrong. Any help or suggestion is appreciated.

推荐答案

此处似乎是正确的。并如该示例所示 app ，尝试使用pip安装依赖项：

The prior configuration as mentioned here seems to be correct. And as shown in this sample app, try installing dependencies with pip:

pip install -t lib -r requirements.txt
