Quickly update Python packages

Python is a good thing，Many times we like to use it to write small things... For example, many services on my server are written in Python ( Supervisor will use your Python program becomes Services ），Accumulate，Many dependency packages are actually used。

but，These Python dependencies will not follow your apt upgrade Update，Today, after a long time，I found a package I am using，Has been updated to 1.10.x，but me，Still using 0.4...

In short，Python's own package manager does not provide a convenient command like apt upgrade Update all packages with one click，We have to think of another way。

One-line command update method

Some articles on the Internet use a complex command to update，The principle is to read pip3 list --outdated (Ironically, pip gives a list of expired packages，But it doesn’t allow you to upgrade them with one click) and then input the result to pip3 install -The ，This scheme is not so stable，Maybe a master who is proficient in shell can use it freely.，I will not provide specific code，Because everyone’s realization is a little different。

Update using pip-review

Don't use the requirements below，Not easy to use，Use pip-review to set and select the dependent packages to be updated one by one，Then batch update，Convenient。

After installing pip-review，Use the following command to use：

use requirements

Is there a more simple and understandable update plan? The answer is yes。

The requirement file is used to solve the one-click configuration environment dependency of Python package distribution，We can also print out the global environment，Then import it in an updated form，Such，The global update is done!

First export global dependencies-that is, all installed packages。

Now we "install" these packages back，But to upgrade ……carry out!
