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.

我怎么解决这个问题？

Answer 1

我遇到了同样的问题,并按照@Tim Lundqvist的回答并通过以下方式解决:

第1步:在家中创建一个隐藏文件夹.命令:

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

第2步:创建符号链接以使其成为可执行文件

$ 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

现在聚合物CLI正在为我工​​作.

更新

此问题node与npm版本相关,但以下命令运行良好

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

Answer 2

以 root 身份安装该软件包似乎存在问题wd。解决这个问题的一种方法是进行非全局 npm 安装polymer-cli并使用本地 bin 路径。

$ cd ~
$ npm install polymer-cli
$ ~/node_modules/.bin/polymer --version
1.1.0

之后，您可以将所有依赖项复制到/usr/lib/node_modules可执行文件/usr/bin/或创建到可执行文件的符号链接（这对于单用户系统可能更容易）。

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

当路径/usr/bin/polymer存在时，您应该能够按polymer预期使用该命令。
