MacOS Sierra install nodejs

It was originally installed with brew, but now it prompts that the version is too low.

• Re-brew install node, installed a 9.4.
• But running node -v, it is always 4.6.
• Find the running path of node: which node
• It's fucking hidden here: /opt/local/bin
• Exclusion: sudo rm / opt / local / bin / node

Reinstall:

• brew install node
• cd /opt/local/bin/
• Establish a soft connection: ln -s /usr/local/Cellar/node/9.4.0/bin/node node
• Running node -v shows that the version is correct.
• But the npm version is too low, and then install npm: brew install npm, but it cannot be installed, prompting node has been installed! ! !
• Node is also TMD too weird! ! !

Finally, go to https://nodejs.org/en/ and download a pkg file , after installation:

• Running node -v still doesn't work.
• Close and reopen the terminal window and node and npm finally work.

Also, on Linux, npm i always fails and needs to set up a proxy .

But npm config edit is useless, use the following method to set:

$npm config set proxy http://server:port
$npm config set https-proxy http://server:port

On MacOS, it is set uniformly in the network and set as a global proxy, and there is no such problem.

I got an error when doing npm install sha3:

[email protected] install: `node-gyp rebuild`

Someone said to do it with the following method ( https://github.com/nodejs/node-gyp/issues/773 ):

cd /usr/local/lib && sudo ln -s ../../lib/libSystem.B.dylib libgcc_s.10.5.dylib

But I still can't.

On Ubuntu someone said to use ( https://github.com/phusion/node-sha3/issues/27 ):

apt-get -y install g++

or:

sudo apt-get install libgmp-dev

Still useless.

Finally, installed the 6x series on Ubuntu, installed g++, and it barely worked.
