运行具有 nltk 依赖项的代码 sn-p 时出现以下错误。

手动安装python 3.6.5并在虚拟环境中使用
操作系统（Red Hat Linux 7.4-Maipo）安装了python 2.7.4。

尝试了以下解决方案，但没有帮助（改用 yum 和 pip）：

solution 1

sudo apt-get install libsqlite3-dev

（或者您可以按照 pyenv wiki 上的建议安装更多软件包：
apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev

现在在下载的python源代码中使用以下命令重建并安装python：./configure --enable-loadable-sqlite-extensions && make && sudo make install。

我的尝试抛出错误：

Collecting libsqlite3-dev
  Could not find a version that satisfies the requirement libsqlite3-dev (from versions: )
No matching distribution found for libsqlite3-dev

【解决方案1】：

回答我自己的问题。

最后通过安装 sqlite-devel 包解决了这个问题：

yum install sqlite-devel

并重新安装python如下：

sudo wget http://python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz
tar xf Python-3.6.5.tar.xz
cd Python-3.6.5
sudo ./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" 
sudo ./configure --enable-optimizations
sudo make && sudo make altinstall

【讨论】：

只是想补充一点，这也修复了我的虚拟 python 环境，ty
执行起来花了很多时间，有人遇到过吗？
@jht 你的意思是多长时间？我没有启用优化，我的电脑花了几分钟的时间来编译和链接所有内容。我认为这可能是相当合理的，但优化可能会更长一些。
