我不能在上部署应用程序。
问题似乎来自我的requirements.txt文件:
requirements.txt文件时,它不能工作*。这是我的requirements.txt
Flask==1.1.1
flask-wtf==0.14.2
unidecode
numpy
openfoodfacts
os当我移除最后两个包时,它就起作用了。
有什么问题吗?

根据您收到的错误,Cloud未能安装您在requirements.txt文件上指定的最后两个依赖项。如果您转到云构建历史记录页面并检查失败的部署,您会注意到部署失败了,并发出了与此类似的错误消息:
Step #1 - "builder": INFO `pip_download_wheels` had stderr output:
Step #1 - "builder": Could not find a version that satisfies the requirement openfoodfacts==0.1.0 (from -r requirements.txt (line 10)) (from versions: )
Step #1 - "builder": No matching distribution found for openfoodfacts==0.1.0 (from -r requirements.txt (line 10))没有必要将os模块包含在requirements.txt上,因为它是Python3.7标准库的一部分。例如,请注意,您的应用程序所来自的main.py导入了日期时间模块,这不是在requirements.txt文件上指定的。
开放式食品包装实际上还没有在PyPI上发布(即https://pypi.org/project/openfoodfacts/是404),因此您需要参考App引擎文档的相关部分并手动添加它,类似于这样:
lib目录(例如,我使用mkdir lib)。lib目录中:pip3 install git+git://github.com/openfoodfacts/openfoodfacts-python.git -t lib。lib目录并验证所有依赖项是否已正确安装。requirements.txt文件以使用Open包所需的依赖项。它应该是这样的:Flask==1.1.1
flask-wtf==0.14.2
unidecode==1.1.1
numpy==1.18.1
certifi==2019.11.28
chardet==3.0.4
idna==2.8
requests==2.22.0
urllib3==1.25.8import lib.openfoodfacts as openff的方式导入应用程序中的模块。gcloud app deploy命令部署应用程序。最后,您应该有一个与此文件结构类似的项目目录:
building-an-app-1/
app.yaml
lib/
...
openfoodfacts/
autosuggest.py
facets.py
__init__.py
openbeautyfacts.py
openpetfoodfacts.py
products.py
__pycache__/
utils.py
...
main.py
requirements.txt
static/
script.js
style.css
templates/
index.html在其中,您可以使用以下方法在os文件上导入main.py和openfoodfacts模块:
...
import datetime
import os
import lib.openfoodfacts as openff
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')

您试过像这样在本地使用这个requirements.txt文件吗?
pip install -r requirements.txt看起来,requirements.txt文件的最后两行与可以用pip安装的Python不相对应。
发布于 2020-02-02 14:59:42
实际上,os和openfoodfacts在requirements.txt文件中的存在(它只需要包含pip可安装的包,请参阅声明和管理依赖项)会导致pip安装错误:
[venv] openfoodfacts> pip install os
Collecting os
Could not find a version that satisfies the requirement os (from versions: )
No matching distribution found for os
[venv] openfoodfacts> pip install openfoodfacts
Collecting openfoodfacts
Could not find a version that satisfies the requirement openfoodfacts (from versions: )
No matching distribution found for openfoodfacts您不需要将os添加到您的需求中,它是标准python安装的一部分,您可以直接导入它。
而且openfoodfacts似乎不是一个普通的Pypi包。如果它来自一个不需要SSH密钥的pip存储库,您可以在requirements.txt文件中指定它,请参见如何向requirements.txt添加特定于包的索引-url?。否则,您需要在您的应用程序中安装它,以便它可以与您的应用程序代码一起上传,检查私有依赖性部分。
您可以/应该始终尝试将在本地安装依赖项作为对requirements.txt文件的正常检查。注意需要SSH密钥的pip,因为在默认情况下,可以通过您的帐户信任来访问这些密钥。
