Question

我无法在Google Cloud Datalab上安装GDAL。我跑的时候：

!pip install gdal

我收到以下错误

Collecting gdal

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

同样的事情：

!pip install gdal==2.2

或：

!pip install python-gdal

和我尝试过的其他一些类似的命令。我发现更新设置工具的修复程序在更新之后仍然给我这个问题。有什么问题？

根据how to add a Python library to Cloud Datalab上的Datalab文档，您可以使用三种方法在Cloud Datalab中安装第三方库：

使用!pip install lib-name。这显然不适合您，即使应用了一些您在环顾四周后找到的故障排除修复程序。
使用下面# Option 2中的代码指定要在Datalab实例的启动脚本中运行的命令，然后继续重新启动它。
使用您自己的Docker自定义容器，继承自Datalab Docker容器。我知道这个选项最复杂，但对于需要更灵活定制的软件包，它可能是最合适的选项，例如您遇到问题的gdal。

选项2中使用的脚本：

#Option 2
%%bash
echo "pip install lib-name" >> /content/datalab/.config/startup.sh
cat /content/datalab/.config/startup.sh
