这是我得到的错误：

我试图安装pyenv以及卸载 python 并重新安装它，但没有运气

该代码在我的笔记本电脑上运行得很好并且运行没有错误，我只有在 google cloud shell 上运行我的代码时才会出现错误。

我安装的要求是：

pandas==0.25.0
nose==1.3.7
tornado==6.0.3
numpy==1.17.0
nltk==3.4.4
pyspellchecker==0.5.0
tqdm==4.32.2
ujson==1.35
cachetools==3.1.1
flask==1.1.1
flask_cors==3.0.8
gevent==1.4.0
openpyxl==2.6.2
xlrd==1.2.0

问题是谷歌云控制台中/上没有名为_lzma 的模块

如果您使用的是 cloud shell，这是一种预期行为，因为 cloud shell vms 是短暂的并且不准备像完整的开发环境一样工作，因此 python 安装不完整，您可以使用计算引擎始终免费的实例来获得尝试您的代码的小型且不可抢占的实例。
