1.1 installation NVM


Use Taobao Mirror



1.2 installation node


Install Taobao image


Installation of yarn


1. Environment installation

Operating system: Ubuntu 16.04.2 LTS

1.1 installation NVM

ryan@ryan- 900.X5L:~/temp$ curl https://raw.githubusercontent.com/creationix/nvm/v033.4./install.sh | bashCopy the code

Use Taobao Mirror

Domestic environment, using Taobao mirror. Configure environment variables, modify. Bashrc append

# taobao npm mirror
export NVM_NODEJS_ORG_MIRROR=http://npm.taobao.org/mirrors/node
Copy the code

1.2 installation node

Install the latest Node

nvm install nodeCopy the code

Or specify the node version

ryan@ryan- 900.X5L:~$ nvm install 6.114.Copy the code

You can then check the current installed version of Node

ryan@ryan- 900.X5L:~$ nvm ls
    iojs-v33.1.
->      v611.4.
         v87.. 0
default -> node (-> v87.0).node -> stable (-> v87.. 0) (default)
stable -> 8.7 (-> v87.. 0) (default)
iojs -> iojs-v33. (-> iojs-v33.1.) (default)
lts/* -> lts/boron (-> v611.4.)
lts/argon -> v48.4.(- >N/A)
lts/boron -> v611.4.Copy the code

You can see that the arrow points to V6.11.4, now switch back to the latest version:

ryan@ryan-900X5L:~$ nvm use 8.7.0Copy the code

You can view the Node version at this point

ryan@ryan- 900.X5L:~$ node -v
v87.. 0
ryan@ryan- 900.X5L:~$ npm -v
5.42.Copy the code

Install Taobao image

npm install -g cnpm --registry=https://registry.npm.taobao.orgCopy the code

Note that the CNPM is installed under the current VERSION of NPM. Such as:

ryan@ryan- 900.X5L:~$ nvm use 6.114.
Now using node v611.4. (npm v310.10.)
ryan@ryan- 900.X5L:~$ node -v
v611.4.
ryan@ryan- 900.X5L:~$CNPM not found'cnpm'Command, you want to enter: command'cpm'From the package'cpm'(universe) command'npm'From the package'npm'(universe) command'cxpm'From the package'xpmutils'(universe) CNPM: The command Ryan was not found@ryan- 900.X5L:~$ nvm use 8.7. 0
Now using node v87.. 0 (npm v54.2.)
ryan@ryan- 900.X5L:~$ cnpm -v
cnpm@5.11. (/home/ryan/.nvm/versions/node/v87.. 0/lib/node_modules/cnpm/lib/parse_argv.js)
npm@5.51. (/home/ryan/.nvm/versions/node/v87.. 0/lib/node_modules/cnpm/node_modules/npm/lib/npm.js)
node@8.7. 0 (/home/ryan/.nvm/versions/node/v87.. 0/bin/node)
npminstall@3.14. (/home/ryan/.nvm/versions/node/v87.. 0/lib/node_modules/cnpm/node_modules/npminstall/lib/index.js)
prefix=/home/ryan/.nvm/versions/node/v87.. 0 
linux x64 4.8. 0- 58-generic 
registry=http://registry.npm.taobao.orgCopy the code

Unfortunately, updating and replacing the NPM requires reinstalling the CNPM. This is recommended:

Add alias to ~/.bashrc:

echo '#alias for cnpm alias cnpm="npm --registry=https://registry.npm.taobao.org --cache=~/.npm/.cache/cnpm --disturl=https://npm.taobao.org/dist --userconfig=~/.cnpmrc"' >> ~/.bashrc && source ~/.bashrcCopy the code

This way, no matter what version NPM switches, CNPM can use:

ryan@ryan- 900.X5L:~$ node -v
v87.. 0
ryan@ryan- 900.X5L:~$ cnpm -v
5.42.
ryan@ryan- 900.X5L:~$ nvm ls
    iojs-v33.1.
        v611.4.
->       v87.. 0
default -> node (-> v87.0).node -> stable (-> v87.. 0) (default)
stable -> 8.7 (-> v87.. 0) (default)
iojs -> iojs-v33. (-> iojs-v33.1.) (default)
lts/* -> lts/boron (-> v611.4.)
lts/argon -> v48.4.(- >N/A)
lts/boron -> v611.4.
ryan@ryan- 900.X5L:~$ nvm use 6.114.
Now using node v611.4. (npm v310.10.)
ryan@ryan- 900.X5L:~$ cnpm -v
3.1010.
Copy the code

If I close terminal, I open it again

ryan@ryan- 900.X5L:~$node The program "node" is not installed. To install nodejs-legacy, run the following command: sudo apt install nodejs-legacyCopy the code

What the hell? Don’t put on?

If this happens, you can look at the current NVM LS and see that no node version is specified. In this case, NVM use 6.11.4 specifies a version.
