Python 3.7.4 不使用 SQLITE 3.29.0

标签 python django sqlite centos7

安装的操作系统/软件:

root@TACIT admin]# cat /etc/*release*
CentOS Linux release 7.6.1810 (Core) 

root@TACIT admin]# python3.7 --version
Python 3.7.4

[root@TACIT admin]# sqlite3 --version
3.29.0 2019-07-10 17:32:03 fc82b73eaac8b36950e527f12c4b5dc1e147e6f4ad2217ae43ad82882a88bfa6

(T3PSA) [root@TACIT src]# django-admin --version
2.2

软件位置:

[root@TACIT admin]# which python3.7
/usr/local/bin/python3.7

[root@TACIT admin]# which sqlite3
/usr/bin/sqlite3

(T3PSA) [root@TACIT src]# which django-admin
/root/.local/share/virtualenvs/T3PSA-6bzDXn0f/bin/django-admin

我从源代码编译了 Python 3.7.4，并按照这些说明安装，没有任何问题:

https://tecadmin.net/install-python-3-7-on-centos/

我按照这些说明从 Sqlite 3.7.17 升级到 Sqlite 3.29.0，没有任何问题(除了我必须安装一些额外的“.so”库):

https://linuxhint.com/upgrade-to-latest-sqlite3-on-centos7/

不幸的是，Python 3.7.4 仍在使用旧版本的 Sqlite3 (3.7.17):

[root@TACIT admin]# python3.7
Python 3.7.4 (default, Aug 16 2019, 16:34:12) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
>>> sqlite3.sqlite_version        
'3.7.17'

我正在使用 Django 并需要它至少运行 v3.8.3(请参阅以下输出的最后):

我查看了以下帖子以尝试解决这个问题，但我认为我对编译代码的了解还不够，无法找出正确的解决方案。我从这些链接中尝试过的任何东西都不起作用。

https://superuser.com/questions/1425212/where-does-django-look-for-sqlite-instance-sqlite-3-8-3-or-later-is-required

https://unix.stackexchange.com/questions/434100/updating-the-sqlite-version-used-by-python-3-on-centos-7

django can't find new sqlite version? (SQLite 3.8.3 or later is required (found 3.7.17))

https://superuser.com/questions/1447285/python-wont-compile-with-a-new-sqlite3-on-centos-7

可能是我遵循的说明不起作用，因为我的软件安装位置/路径与上述帖子中的用户不同，我不确定...这就是为什么我注意到“软件位置: “多于。或者我可能需要以某种方式卸载 Python 3.7，而不是在现有安装的基础上“重新安装”？我是从源代码安装的，不确定是否需要这样做，如果需要，如何正确进行。

如果您能帮助解决这个问题，我们将不胜感激。提前致谢!

本节是在从 FlipperPA 获得说明后添加的

完全按照说明“通过从源代码编译将 SQLite 的 CentOS 7 系统安装升级到 3.29”。下面是结果。

[root@TACIT src]# sqlite3 --version
3.29.0 2019-07-10 17:32:03 fc82b73eaac8b36950e527f12c4b5dc1e147e6f4ad2217ae43ad82882a88bfa6

昨天我已经多次删除了我的原始源代码编译目录 (/usr/src/Python-3.7.4)，因为我尝试了原始帖子中的所有其他文章。所以从头开始，我这样做了:

cd /usr/src
tar -zxvf Python-3.7.4.tgz
cd Python-3.7.4
./configure --enable-optimizations
make altinstall
make clean
make install

[root@TACIT Python-3.7.4]# python3.7
Python 3.7.4 (default, Aug 17 2019, 08:20:39) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
>>> sqlite3.sqlite_version
'3.7.17'

Python 仍在使用错误版本的 SQLite。我执行了“make altinstall”命令，因为 CentOS 7.6 默认带有 Python 2.7.5，我读到我不应该搞砸它。因此“make altinstall”将 Python 3.7.4 安装在另一个位置，以便完整保留 python 的默认安装。

============================================= ==========================

手动卸载 Python 3.7.4(从源安装)

所以我做了以下事情:

find / -name *3.7*

生成的文件列表如下。我单独留下的第一组文件/文件夹。我删除的第二组文件/文件夹。

/var/lib/yum/yumdb/s/27f7f0189d0898d0e87007d97102619629a4de6d-sqlite-3.7.17-8.el7-x86_64

/usr/src/Python-3.7.4/build/scripts-3.7/pyvenv-3.7
/usr/src/Python-3.7.4/libpython3.7m.a

然后我做了以下步骤:

tar -zxvf Python-3.7.4.tgz
cd Python-3.7.4
./configure --prefix=/usr --enable-optimizations
make
make altinstall
[root@TACIT Python-3.7.4]# python3.7
Python 3.7.4 (default, Aug 17 2019, 16:34:42)

Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3    
>>> sqlite3.sqlite_version
'3.7.17'

不知道我还能在这里做什么。

最佳答案

我认为 OP 在安装 Python 时必须修复 sqlite3 的路径:

sudo LD_RUN_PATH=/usr/lib ./configure --enable-optimizations
sudo LD_RUN_PATH=/usr/lib make altinstall
