list命令(说有可用的更新)和update命令(找不到任何更新)之间似乎存在冲突".怎么会这样?

It seems like there's a "conflict" between the list command which is saying there are updates available, and the update command which can not find any... how can this happen?

推荐答案

问题似乎出在mrt migrate-app脚本上，这是一种方便的升级方式...但是显然有些麻烦.

The problem seemed to be the mrt migrate-app script, which was a convenient way to upgrade... but apparently left some cruft around.

1. 有人猜测某些软件包有误……使用cmather:iron-router时应为iron:router，更像是……(希望有某种方法可以过滤/投票/识别好"软件包)
2. 一些软件包添加了像@2.0.0这样的版本后缀，而这些后缀却阻止了更新...因此list说有可用的更新"，但是update没有得到它们... <-答案

1. some of the packages were guessed a bit wrong... with cmather:iron-router when it should be iron:router and more like that... (wish there was some way to filter/vote/identify "good" packages)
2. some of the packages were added with version suffixes like @2.0.0 and those were holding up the update... so list says "there are updates available" but update doesn't get them... <-- answer

解决方案

删除所有软件包，更新，全部添加回去，而没有版本后缀... 现在它们都很容易了，因为它们都是.meteor/packages文件中的单行:

solution

remove all packages, update, add them all back, without the version suffix... pretty easy to do now that they are all single lines in the .meteor/packages file:

sed -e 's/^[a-zA-Z0-9]/meteor remove &/' .meteor/packages | sed 's/\@[0-9\.]*//g' > packages-rm.sh
sed -e 's/ remove / add /' packages-rm.sh > packages-add.sh
bash packages-rm.sh
meteor list  # should be empty
meteor update
bash packages-add.sh
meteor list
