Ignore .pyc files in git repository

How can I ignore .开发者_如何学编程pyc files in git?

If I put it in .gitignore it doesn't work. I need them to be untracked and not checked for commits.

You should add a line with:

*.pyc 

to the .gitignore file in the root folder of your git repository tree right after repository initialization.

As ralphtheninja said, if you forgot to to do it beforehand, if you just add the line to the .gitignore file, all previously committed .pyc files will still be tracked, so you'll need to remove them from the repository.

If you are on a Linux system (or "parents&sons" like a MacOSX), you can quickly do it with just this one line command that you need to execute from the root of the repository:

find . -name "*.pyc" -exec git rm -f "{}" \;

This just means:

starting from the directory i'm currently in, find all files whose name ends with extension .pyc, and pass file name to the command git rm -f

After *.pyc files deletion from git as tracked files, commit this change to the repository, and then you can finally add the *.pyc line to the .gitignore file.

You have probably added them to the repository before putting *.pyc in .gitignore.
First remove them from the repository.

Put it in .gitignore. But from the gitignore(5) man page:

  ·   If the pattern does not contain a slash /, git treats it as a shell
       glob pattern and checks for a match against the pathname relative
       to the location of the .gitignore file (relative to the toplevel of
       the work tree if not from a .gitignore file).

  ·   Otherwise, git treats the pattern as a shell glob suitable for
       consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in
       the pattern will not match a / in the pathname. For example,
       "Documentation/*.html" matches "Documentation/git.html" but not
       "Documentation/ppc/ppc.html" or
       "tools/perf/Documentation/perf.html".

So, either specify the full path to the appropriate *.pyc entry, or put it in a .gitignore file in any of the directories leading from the repository root (inclusive).

i try to use the sentence of a prior post and don't work recursively, then read some help and get this line:

find . -name "*.pyc" -exec git rm -f "{}" \;

p.d. is necessary to add *.pyc in .gitignore file to maintain git clean

echo "*.pyc" >> .gitignore

Enjoy.

If you want to ignore '.pyc' files globally (i.e. if you do not want to add the line to .gitignore file in every git directory), try the following:

$ cat ~/.gitconfig 
[core]
    excludesFile = ~/.gitignore
$ cat ~/.gitignore
**/*.pyc

[Reference]
https://git-scm.com/docs/gitignore

• Patterns which a user wants Git to ignore in all situations (e.g., backup or temporary files generated by the user’s editor of choice) generally go into a file specified by core.excludesFile in the user’s ~/.gitconfig.

• A leading "**" followed by a slash means match in all directories. For example, "**/foo" matches file or directory "foo" anywhere, the same as pattern "foo". "**/foo/bar" matches file or directory "bar" anywhere that is directly under directory "foo".

if you have committed in the repo, just

1. go to the folder /__pycache__,
2. delete all of them (no worries, they are temporary files and generated repeatedly)
3. have a new commit, such as 'update gitignore'
4. you are done! .pyc will not appear again.

Thanks @Enrico for the answer.

Note if you're using virtualenv you will have several more .pyc files within the directory you're currently in, which will be captured by his find command.

For example:

./app.pyc
./lib/python2.7/_weakrefset.pyc
./lib/python2.7/abc.pyc
./lib/python2.7/codecs.pyc
./lib/python2.7/copy_reg.pyc
./lib/python2.7/site-packages/alembic/__init__.pyc
./lib/python2.7/site-packages/alembic/autogenerate/__init__.pyc
./lib/python2.7/site-packages/alembic/autogenerate/api.pyc

I suppose it's harmless to remove all the files, but if you only want to remove the .pyc files in your main directory, then just do

find "*.pyc" -exec git rm -f "{}" \;

This will remove just the app.pyc file from the git repository.

Zachary's answer is correct. The reason that it's likely correct in your case is that gitignore will not work for files that preexist the gitignore (or the repository).
