Upgrade To Python 3.7 Mac

  

Question or issue on macOS:

Python 3.7.1 is still in maintenance version. It is only available for download to Windows and macOS users. Once the stable version is released, then it is made available in Linux repositories. For Windows and Mac users visit this python.org URL. For Linux users: you can download the 3.7.0 version from the terminal. Note, this article is a significant revision to the original article from July 23, 2014, “How to Upgrade Your Mac to Python 3. Apple Only Provides Python 2.7 in macOS.

Upgrade To Python 3.7 Mac Version

I would like to use the SQLite version 3.8 with Python, but the SQLite3 module is using an out of date version. I’ve installed SQLite version 3.8.4.3 on my Mac, but sqlite3.sqlite_version still returns 3.7.13.

I’ve done quite a bit of searching on SO and elsewhere, but can’t seem to find a definitive answer.

How to solve this problem?

Solution no. 1:

From your comments, your problem is that your pre-installed sqlite 3.7 comes higher on your path than your third-party 3.8. This means that when you build pysqlite2, by default, it will find and use that 3.7, so it’s not doing you any good. And you probably don’t want to change around your whole path just to deal with this.

But that’s fine, as long as the 3.8 is found first at build time, it doesn’t matter what comes first at runtime; the path to 3.8 will be baked into the module. There are a number of ways to do this, but the simplest is something like this:

The LDFLAGS and CPPFLAGS variables came from the output of the brew install sqlite3 step. If you’ve installed sqlite3 in some other way, you’ll need to get the appropriate values—possibly /usr/local/lib and /usr/local/include, but if not, search for libsqlite3.dylib and sqlite3.h.

Note that if you follow exactly these steps, you’ll get a non-fat version of libsqlite3, meaning that pysqlite2 won’t work in 32-bit mode. I doubt that’s an issue for you, but if it is, you can just install it --universal, or use a different installer instead of Homebrew.

Solution no. 2:

If you use Anaconda as your package manager, run conda install -c anaconda sqlite.

Run python -c 'import sqlite3; print(sqlite3.sqlite_version)' to confirm that you have the latest version.

Solution no. 3:

I think the easiest way is to update your Python to the latest version because sqlite3 is shipped with Python.

Otherwise have to update the pysqlite package as well. Under Linux there is a precompiled package python-sqlite.

You can do that by using easy_install. For building this package you need some packages. Nessecerily build pysqlite with the new installed version of sqlite3, in your case 3.8.4.3.
