npm - Can't install phantom-js to angular project. -


i add phantomjs library angular4 project continuous integration jenkins. tried dfo in many ways, same (or similar) error.

for example, this tutorial when tried install phantomjs , launcher in way: npm install --save-dev phantomjs-prebuilt karma-phantomjs-launcher got error:

npm err! path c:\users\jarkro\appdata\roaming\npm\node_modules\phantomjs-prebuilt\node_modules\sshpk\node_modules\assert-plus\package.json npm err! code eperm npm err! errno -4048 npm err! syscall unlink npm err! error: eperm: operation not permitted, unlink 'c:\users\jarkro\appdata\roaming\npm\node_modules\phantomjs-prebuilt\node_modules\sshpk\node_modules\assert-plus\package.json' npm err!     @ error (native) npm err!  { error: eperm: operation not permitted, unlink 'c:\users\jarkro\appdata\roaming\npm\node_modules\phantomjs-prebuilt\node_modules\sshpk\node_modules\assert-plus\package.json' npm err!     @ error (native) npm err!   cause: npm err!    { error: eperm: operation not permitted, unlink 'c:\users\jarkro\appdata\roaming\npm\node_modules\phantomjs-prebuilt\node_modules\sshpk\node_modules\assert-plus\package.json' npm err!        @ error (native) npm err!      errno: -4048, npm err!      code: 'eperm', npm err!      syscall: 'unlink', npm err!      path: 'c:\\users\\jarkro\\appdata\\roaming\\npm\\node_modules\\phantomjs-prebuilt\\node_modules\\sshpk\\node_modules\\assert-plus\\package.json' }, npm err!   stack: 'error: eperm: operation not permitted, unlink \'c:\\users\\jarkro\\appdata\\roaming\\npm\\node_modules\\phantomjs-prebuilt\\node_modules\\sshpk\\node_modules\\assert-plus\\package.json\'\n    @ error (native)', npm err!   errno: -4048, npm err!   code: 'eperm', npm err!   syscall: 'unlink', npm err!   path: 'c:\\users\\jarkro\\appdata\\roaming\\npm\\node_modules\\phantomjs-prebuilt\\node_modules\\sshpk\\node_modules\\assert-plus\\package.json', npm err!   parent: 'phantomjs-prebuilt' } npm err! npm err! please try running command again root/administrator.

for clarification: have administrator praviliage.

anyone can me , tell me whats going on?

ok. found solution / walkaround. has moved here , here.

latest npm version have bugs installing libaries, in case when use fsevent dependency. in case, have downgrade npm version 5.0.3.

just use command:

npm install -g npm@5.0.3

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
