更新hexo插件

检查更新

npm outdated

lan@DESKTOP-8ISAT6B MINGW64 /e/Blog/exam (master)
$ npm outdated

hexo-server               1.0.0   1.0.0   2.0.0  hexo-site

我这里的hexo是4.2.1这已经是hexo4的最高版本了，我之前有试过升级到hexo5,但是会打不开站点。所以我就升级插件就行了，hexo就不更新了。
如果需要用hexo5的话，可能要重新使用hexo init创建一个新的站点，然后将原来的文章复制过去才行。

修改package.json

更新要升级的插件的版本号：

$ git diff package.json
warning: LF will be replaced by CRLF in package.json.
The file will have its original line endings in your working directory
diff --git a/package.json b/package.json

安装更新

npm install --save

从Git版本库中删除已经添加的文件package-lock.json

这个文件是npm install命令生成的，里面存放有插件的地址，没有必要加入版本库，我之前不知道，没有将该文件排除在外。

在.gitignore添加该文件

打开.gitignore文件，把package-lock.json添加到其中。

lan@DESKTOP-8ISAT6B MINGW64 /e/Blog/exam (master)
$ git diff .gitignore
diff --git a/.gitignore b/.gitignore
index 122aa34..8b3df4c 100644

\ No newline at end of file

使用git rm –cached命令删除已经添加过的文件

.gitignore只对新添加的文件有效，由于package-lock.json文件已经在版本库中。所以此时.gitignore对该文件没有影响。
现在接着使用git rm –cached删除该文件即可：

git rm -n –cached

为了以防删错，可以多添加-n参数(git rm -n –cached)，这样会显示你要删除的文件，但不会真正的删除。
等确认是你要删除的文件后，再去掉-n参数，使用git rm –cached 删除即可。

删除效果：

lan@DESKTOP-8ISAT6B MINGW64 /e/Blog/exam (master)
$ git rm -n --cached package-lock.json
rm 'package-lock.json'

lan@DESKTOP-8ISAT6B MINGW64 /e/Blog/exam (master)
$ git rm --cached package-lock.json
rm 'package-lock.json'
