Bazel build issues npm install failed

[Shiwen K]

Yesterday I successfully build onos 2.7.0 , but when I try to implement the same procedures today on another machine I got stuck with the npm issues. I remember I had the same problem yesterday, I was able to solve it by reinstall npm, but iI won't work today.

First, I tried to use 'which npm" and remove all relevant files by using

    sudo apt-get remove --purge npm
    sudo apt-get remove --purge nodejs
    sudo apt-get remove --purge nodejs-legacy
    sudo apt-get autoremove

Second, I turned off my proxy settings so my machine could directly access the internet.

And the following errors keeps the same.

Hi,

Every time I see these errors, I never remember the best approach to solve them.

I can see the error is "Error in fail: npm_install failed:  (Unhandled rejection Error: EACCES: permission denied, mkdir". Did you do any of the previous steps as root? Seems like a permission error could be because of that.

I believe your solution is likely in one of these three previous threads. Check this, this or this.

Cheers,
