javascript - 警告查找 github :systemjs/systemjs 时出错

Question

当我使用以下命令设置 jspm 安装时:

jspm init

然后它只询问我初始配置:

Would you like jspm to prefix the jspm package.json properties under jspm? [yes]:yes

Enter server baseURL (public folder path) [./]:app
Enter jspm packages folder [app/jspm_packages]:
Enter config file path [app/config.js]:
Configuration file app/config.js doesn't exist, create it? [yes]:yes
Enter client baseURL (public folder URL) [/]:
Do you wish to use a transpiler? [yes]:no

紧接着，我收到此错误消息:

不确定那里发生了什么。所以我来这里寻找一些线索。

在尝试了太多之后，发现是怎么回事。我来了，碰巧 Jspm 没有问题，但我的 Node 和 Npm 版本是预发布的(这似乎影响了 Jspm 注册表)。我使用的是 NodeJs 8.0.0。无论如何，如果有人坚持同样的做法，他/她应该知道回到

node v6.10.3 (npm v3.10.10) versions

解决这个小问题。

对我有用，下面的命令:

brew update
brew install nvm
source $(brew --prefix nvm)/nvm.sh (adding to ~/.profile)

nvm install 6.10.3
