启动脚本无法安装pip3

Question

我想在GCP中将一个启动脚本传递给我的免费F1微实例VM。我指定的命令如下：

gcloud compute instances create dora-scanner --zone=us-central1-a --machine-type=f1-micro --metadata-from-file startup-script=./startup-script-dora.sh

启动脚本内容很简单--我正在安装pip3以下载我想要使用的Python3库。

#! /bin/bash
apt-get update

# install pip3
apt-get install python3-pip

# install requests and beautifulsoup4
pip3 install requests
pip3 install bs4

但是，当我试图加载Python3中的库时，当我将ssh加载到实例中时，会出现一个错误，这表明启动脚本没有工作。因此，我环顾四周，从控制台指向日志，它看起来如下：

我想就如何绕过(是/否)对installation

• Why prod.debian.map.fastly.net:80)?

的(是/否)问题寻求帮助，我得到了一个连接错误(无法连接到prod.debian.map.fastly.net:80)？)吗？

这是我第一次使用GCP，所以非常感谢您的指导！

Answer 1

当没有-y arg安装任何apt包时，它将以交互式模式运行，并具有提示符。

Do you want to continue? [Y/n] Abort.

在您的启动脚本中，安装pip的命令处于交互式模式，如果它没有将y作为输入，那么它就不会安装pip包。

# install pip3
apt-get install python3-pip

溶液

替换开始-脚本行

# install pip3
apt-get install python3-pip

使用

# install pip3
apt-get install -y python3-pip
