Failing to install ghost local install

When i try to install ghost using the ghost local command i keep getting the following error:
error https://registry.yarnpkg.com/gscan/-/gscan-3.5.4.tgz: Extracting tar content of undefined failed, the file appears to be corrupt: "ENOENT : no such file or directory, symlink 'test/fixtures/themes/030-assets/symlink/assets/foo.png' -> '/home//.cache/yarn/v6/npm-gscan-3.5.4 -b9214433b5e866d364e4997b32b2d2c8f5a5fef7-integrity/node_modules/gscan/test/fixtures/themes/030-assets/symlink/assets/mysymlink.png'"
I've tried different versions and node versions but I always get the same error, anyone came across this before? Thanks
if you are using yarn, try this below:
yarn cache clean
yarn install --network-concurrency 1
also if you still facing the error try to delete the yarn.lock file and reinstall.

path variable of yarn

I have installed yarn in my 16.04 LTS version according to this tutorial tutorial
have added the environment path as well, but the termial does not take any yarn commands.
on typing yarn init, it gives ::-
ERROR: [Errno 2] No such file or directory: 'init'
same for when i type yarn global bin ::-
ERROR: [Errno 2] No such file or directory: 'global'
I think it is because of the PATH variable issue, can anyone tell me what else i need to add.
Thanks
So i found the resolution to this problem . their is a package called cmdtest which was installed in my system, which also contained a package called yarn.
This yarn was conflicting with the yarnpkg, and when i was running yarn init or any other yarn commands it was probably running that yarn package with the argument, hance the error. the yarn --version and which yarn was running correctly which further convoluted the issue. i uninstalled cmdtest and installed yarn again which fixed the issue. More details about this issue can be found in this bug report

ionic cli: all commands giving error undefined:1 SyntaxError: Unexpected token

I have downloaded and installed nodejs (setup file node-v0.12.5-x64) in my Windows7 pc.
Also installed ionic via command: npm install -g ionic cordova
All ionic commands are giving same error i.e. undefined:1.
In command prompt it looks like below:
E:\programs>ionic -v
undefined:1
SyntaxError: Unexpected token
I am not able to resolve after many installation and un-installation.
Please help.
The issue on another thread
My C:\Users\USER\ .ionic\ionic.config had been corrupted and deleting it solved the issue
if that's not the issue then navigate to where you have ionic installed, for me it's
C:\Users\USER\AppData\Roaming\npm\node_modules\ionic\lib\ionic
then open a command prompt and run "npm install -g node-debug
after installing run "node-debug app.js" from that folder and step through the program to identify the error
