如何在Amazon EC2實例上安裝nltk？

Question

我正在嘗試使用pip和虛擬環境在Amazon EC2實例上安裝nltk。 pip使用的requirements.txt文件中列出了nltk。 我也想使用nltk.download('punkt')選項下載punkt 。

這是我的makefile樣子：

INSTANCE_NAME=toolsapp
ENV=env
LOAD_ENV=source $(ENV)/bin/activate
VIRTUALENV_BIN:=$(shell which virtualenv || echo /usr/local/bin/virtualenv )
EB_BIN:=$(shell $(LOAD_ENV) && which eb || echo /usr/local/bin/eb )
AWS_BIN:=$(shell $(LOAD_ENV) && which aws || echo /usr/local/bin/aws )

default: dev
.PHONY: default

# Ensure virtualenv is installed
$(VIRTUALENV_BIN):
    pip3 install virtualenv

# Create a virtualenv folder called env/ and install dependencies
$(ENV): $(VIRTUALENV_BIN)
    virtualenv -p python3 $(ENV)
    $(LOAD_ENV) && pip install --upgrade pip && pip install -r requirements.txt

但這是我嘗試運行webapp時遇到的錯誤：

安裝nltk之后，添加腳本以下載所需的模型。

python3 -m nltk.downloader punkt
python3 -m nltk.downloader stopwords
