git 设置 gitignore 忽略 __pycache__

清除git缓存中的pycache

直接删掉硬盘上的文件

JUNWEI1+lijw@junwei1 MINGW64 /d/pythonProject/django-test (master)
$ git rm -r apis/__pycache__
error: the following files have local modifications:
    apis/__pycache__/urls.cpython-37.pyc
    apis/__pycache__/views.cpython-37.pyc
(use --cached to keep the file, or -f to force removal)

JUNWEI1+lijw@junwei1 MINGW64 /d/pythonProject/django-test (master)
$ git rm -r -f apis/__pycache__
rm 'apis/__pycache__/__init__.cpython-37.pyc'
rm 'apis/__pycache__/admin.cpython-37.pyc'
rm 'apis/__pycache__/apps.cpython-37.pyc'
rm 'apis/__pycache__/models.cpython-37.pyc'
rm 'apis/__pycache__/urls.cpython-37.pyc'
rm 'apis/__pycache__/views.cpython-37.pyc'

如果我想保留硬盘上的这个文件，而只删除版本管理中的文件，就需要加入--cached参数。

切换分支出现问题

JUNWEI1+lijw@junwei1 MINGW64 /d/pythonProject/django-test (master)
$ git checkout download-api
error: Your local changes to the following files would be overwritten by checkout:
        apis/__pycache__/urls.cpython-37.pyc
        apis/__pycache__/views.cpython-37.pyc
Please commit your changes or stash them before you switch branches.
Aborting

尽管我已经删除了__pycache__，硬盘也没有了，但是切换分支的时候依然是会提示本地重写的情况。

提示：需要我在切换分支之前，提交一次更新。

$ git commit -m "delete __pycache__"
[master f82b0ab] delete __pycache__

提交了更新之后，再来尝试切换分支，如下：

JUNWEI1+lijw@junwei1 MINGW64 /d/pythonProject/django-test (master)
$ git branch
  download-api
* master
  upload-api

JUNWEI1+lijw@junwei1 MINGW64 /d/pythonProject/django-test (master)
$ git checkout download-api
Switched to branch 'download-api'
Your branch is up to date with 'origin/download-api'.

成功了，说明当做了任何变更之后，切换分支前需要执行commit一下变化。

好了，为了避免再次会将__pycache__上传到仓库，下面设置一下忽略。

设置 .gitignore 忽略 __pycache__

$ cat .gitignore
/.idea/
*/__pycache__
