NLTK 3.2.2 安装经验
- Nltk 3.2.2要求Python版本是Python2.7 或者Python3.4+。
- Nltk 3.2.3 如果是从网站上直接下载程序进行安装可能会报错:Python version -32 required, which was not found in the registry,
原因可能有以下几方面:
1) Python版本不对:重新安装合适的Python版本
2) Python注册信息未加入到注册表中
3) Python注册信息不对
针对后面两种情况,我们可以直接通过脚本register.py(具体代码内容见本文后面)建立注册信息,然后运行该脚本。注册信息添加成功后重新安装nltk模块即可。
- Python3.0 以上版本都自带有pip,可以通过pip快捷安装nltk的最新版本,但为了保证库的版本最新,可以先更新pip
1) 更新pip:py –m pip install –upgrade pip
2) 安装nltk: py –m pip install nltk
当出现打印消息:successfully installed nltk-3.2.2 six-1.10.0时表示安装成功。
