Ubuntu上的polymer-cli安装失败

Question

无论我尝试什么，每次我尝试安装 polymer-cli 时，总是会出现 PERMISSION_DENIED 错误。

bradley@gurulaptop:~$ sudo npm -g install polymer-cli
npm WARN deprecated bower@1.8.0: ..psst! While Bower is maintained, we recommend Yarn and Webpack for *new* front-end projects! Yarn's advantage is security and reliability, and Webpack's is support for both CommonJS and AMD projects. Currently there's no migration path but we hope you'll help us figure out one.

我该如何解决这个问题？

Answer 1

我遇到了同样的问题并遵循@Tim Lundqvist的回答并通过以下方式解决:

第一步:在 home 中创建一个隐藏文件夹。命令:

$ cd ~
$ mkdir .polymer-patch
$ cd .polymer-patch
$ npm install polymer-cli

第二步:创建符号链接(symbolic link)以使其可执行

$ sudo ln -s "$(readlink -f ~/.polymer-patch/node_modules/.bin/wd)" /usr/bin/wd
$ sudo ln -s "$(readlink -f ~/.polymer-patch/node_modules/.bin/polymer)" /usr/bin/polymer
$ polymer

现在polymer CLI正在为我工​​作。

更新

这个问题是node和 npm版本相关，但以下命令效果很好

$ sudo npm install --unsafe-perm -g polymer-cli
