Question

在尝试为Python3.4安装ipython时，我收到一条消息，表明它已经安装。

pip3 install ipython
Requirement already satisfied (use --upgrade to upgrade): ipython in /usr/local/lib/python3.4/site-packages

但是当我尝试用ipython3 notebook运行它时，我得到了所有这些：

Traceback (most recent call last):
  File "/usr/local/bin/ipython3", line 11, in <module>
sys.exit(start_ipython())

  File "/usr/local/lib/python3.4/sqlite3/dbapi2.py", line 27, in <module>
from _sqlite3 import *
ImportError: No module named '_sqlite3'

假设最后一行是最重要的

ImportError: No module named '_sqlite3'

我尝试为它安装各种依赖项：

apt-get install sqlite3 libsqlite3-dev

当我尝试通过pip3 install pysqlite安装Pysqlite时：

Collecting pysqlite
  Using cached pysqlite-2.6.3.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 20, in <module>
      File "/tmp/pip-build-ggtq7_wu/pysqlite/setup.py", line 85
        print "Is sphinx installed? If not, try 'sudo easy_install sphinx'."
                                                                       ^
    SyntaxError: Missing parentheses in call to 'print'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ggtq7_wu/pysqlite

但是已经安装了Sphinx。我甚至重新安装了它。

pip3 install sphinx
Requirement already satisfied (use --upgrade to upgrade): sphinx in /usr/local/lib/python3.4/site-packages
Requirement already satisfied (use --upgrade to upgrade): Jinja2>=2.3 in /usr/local/lib/python3.4/site-packages (from sphinx)

Requirement already satisfied (use --upgrade to upgrade): pytz>=0a in /usr/local/lib/python3.4/site-packages (from babel>=1.3->sphinx)

因此我无法解决它，因为显然_sqlite3.so中的文件/usr/local/lib/python3.4/lib-dynload不存在，我找不到安装它的方法。

Answer 1

由于我在评论中得到的帮助，我设法解决了这个问题只是把它放在这里，以便让任何可能有同样问题的人轻松搞清楚最新情况。

问题是在安装sql dev文件之前使用Python的自编译版本。因此绑定没有采取。

首先，我必须使用sudo apt-get install sqlite3 libsqlite3-dev来获取相关的sqlite文件。
然后我不得不使用Source Tarball重新编译Python并执行以下命令来重新编译它。

make clean
./configure 
make 
make install

Answer 2

我在CentOS 6.8上遇到了同样的问题，我安装了sqlite-devel然后我重新编译了python并解决了问题：

yum install sqlite-devel

Ipython：安装错误，无法找到_sqlite.so
