Ubuntu 升级npm 以及安装cross-env 过程中遇到的问题

　　

npm 安装过程中出现的问题:

1. npm的升级：

npm升级流程如下:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

　　升级的原因，在npm install 的时候出现下面的错误:

.....................
npm ERR! Error: No dist in undefined package
npm ERR!     at next (/usr/share/npm/lib/cache.js:746:26)
npm ERR!     at /usr/share/npm/lib/cache.js:739:5
npm ERR!     at saved (/usr/share/npm/node_modules/npm-registry-client/lib/get.js:142:7)
npm ERR!     at /usr/lib/nodejs/graceful-fs/polyfills.js:133:7
npm ERR!     at Object.oncomplete (fs.js:107:15)
npm ERR! If you need help, you may report this log at:

npm ERR! or email it to:
npm ERR!     <npm-@googlegroups.com>

npm ERR! System Linux 4.4.0-137-generic
npm ERR! command "/usr/bin/nodejs" "/usr/bin/npm" "install"
npm ERR! cwd /home/darrykinger/blog57
npm ERR! node -v v0.10.25
npm ERR! npm -v 1.3.10
.............

　　参考github 牛人的提示说，这是由于其npm的版本比较旧了，要使用比较新的版本，大于1版本的比较好

 2. cross-env命令找不到，错误提示如下：

 

darrykinger@darrykinger-laravel:/mnt/hgfs/workspace/blog57$ sudo npm run dev
[sudo] password for darrykinger: 

> @ dev /mnt/hgfs/workspace/blog57
> npm run development


> @ development /mnt/hgfs/workspace/blog57
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

　　错误分析:

          没有找到cross-env包

      解决方案，安装cross-env 

         

sudo npm install cross-env

3. 我在安装crosfs-env的情况，这种情况出现的错误如下:

darrykinger@darrykinger-laravel:/mnt/hgfs/workspace/blog57$ sudo npm install cross-env
npm ERR! path ../semver/bin/semver
npm ERR! code ENOTSUP
npm ERR! errno -95
npm ERR! syscall symlink
npm ERR! nospc ENOTSUP: operation not supported on socket, symlink '../semver/bin/semver' -> '/mnt/hgfs/workspace/blog57/node_modules/.bin/semver'
npm ERR! nospc There appears to be insufficient space on your system to finish.
npm ERR! nospc Clear up some disk space and try again.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/darrykinger/.npm/_logs/2019-04-08T12_13_05_644Z-debug.log

npm ERR! nospc ENOTSUP: operation not supported on socket, symlink '../semver/bin/semver' 

　　错误原因分析:

       我的项目所在目录，是通过vmware 的文件共享功能，将window 的一个目录，共享到vmware 的linux中去，通过挂载到/mnt/hgfs/workspace/my_project_dir  下，

　　而挂载的目录，通过执行ln -s 的时候，发现不能 支持建立软连接 ，只有是属于系统本身的目录才能进行软连接处理

        将项目移动到/home/current_user_name/ 下，然后执行以上命令，发现没有问题了。
