Question

在运行具有nltk依赖性的代码段时遇到错误。

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

ModuleNotFoundError: No module named '_sqlite3'

尝试以下解决方案，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。

我的尝试抛出以下错误：

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

Answer 1

回答我自己的问题。

最后通过安装sqlite-devel软件包解决了该问题：

yum install sqlite-devel

并按如下所示重新安装python：

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

在安装nltk软件包时，获取ModuleNotFoundError：没有名为“ _sqlite3”的模块
