This is the flow often happens in this case  You run a command with no admin rights  you get message npm ERR  Please try running this command again as root Administrator   Then you open one more CLI cmd  powershell  bash or whatever  and don t close the previous CLI  It appears you have 2 prompts opened in the same directory  And until you close CLI which runs with no admin rights you will be continuously getting npm ERR  Please try running this command again as root Administrator  So close CLI which runs with no admins rights before running a new one   NOTE  a lot of IDE has embedded CLI Visual Studio  VS Code etc  so please close the instance of IDE as well

Here is how I fixed this on my Windows  7  Dev  environment   I assume the following      You are Running  Command Prompt  Git Bash  Cmder or your favorite Terminal  as an Administrator by right clicking Privileges Permissions have been granted for Read Write  i e chmod -777    Okay  let s get to it    Update any packages where a version check is returning a warning   npm WARN     for example     npm update -g npm  npm update -g graceful-fs Next we want to force a cache clean  This is flagged by an  --f  or  -f     npm cache clean --f In Widows Explorer search for the following path             APPDATA  npm-cache      And Delete it s contents   Start a fresh instance of your Terminal  remembering to  Right-Click  and  Run as Administrator   install the packages again    Hope this helps someone

On windows 10  npm cache clean --force and npm cache verify did not work for me   Tried to delete cache folder and file with administrator permission  did not work   The process-explorer tool helped me finding that Node exe is holding on the cache file  I killed the process and tried to clean  worked

Close the IDE Close the node terminals running ng serve or npm start Go to your project folder node modules and see you if can find the package that you are trying to install If you find the package you are searching then delete package folder In case  this is your 1st npm install then skip step 4 and delete everything inside the node modules  If you don t find node modules then create one folder in your project  Open the terminal in admin mode and do npm install    That should fix the issue hopefully

I don t know which steps worked for me  But these are my steps to get rid of this error    Updated Node js  Ran npm cache clean command in Command prompt   With some element of doubt for cache presence  Ran react-native init in command prompt as Administrator  on Windows OS   hoping works well with sudo react-native init on Mac OS

Deleting the global npm-cache and or running my cmd line as admin did not work for me  Also  as of npm version 5 x x  it supposedly recovers from cache corruption by itself   This did work   1  Deleted the node modules folder in my current project   2  Deleted the package-lock json in my current project  3  Installed the new package  In my case  npm install bootstrap next --save  4  Ran npm install for my current project   Everything now works  In general  nuking node modules and package-lock json usually fix these  no apparent reason  bugs for me   EDIT  I just had the same problem again  But I noticed that everything was installed correctly even though it threw the error after I had followed the steps outlined above  So I could just run ng serve  for Angular   and everything worked    This sure is a weird error

I messed with this problem 2 times and tried all suggestions here with mediocre success    First time I tried  and succeeded luckily  by    delete the node modules folder in your project npm clean cache -f check your  APPDATA  npm-cache and delete everything if not empty start the terminal as administrator  in my opinion  it isnt a problem of rights  but it wont hurt if you do so   npm install and then npm update you will get errors  just install every module that throws an error manually and step by step try to eliminate everything whats wrong    However  this method is quite frustrating and not working everytime  So try this    Second time I had no luck with the steps above  so I tried to completely reinstall npm and it failed  So I thought there must something be wrong with my node js installation  My team is running 6 10  and I had the 6 11  and tried it with the 6 10  with no luck    So I completely wiped everything off my system  Deleted all node modules  checked every path where node or npm could be and cleaned my system   Then I installed newest 8 1 3 Deleted my project and cloned it to a complete different directory  Now I installed and updated everything with npm install npm update Then I compiled with just 2 modules missing and installed them manually    Tadaaaaa  its working now  So all in all it was a problem with node js  I recommend to everyone who runs into this problem  Try different node versions  And clean ABSOLUTE everything

Here is how I fixed the problem in Windows  I was trying to install the CLI for Angular    Turn off firewall and antivirus protections  Right click the nodejs folder  under Program Files   select Properties  scroll all the way down   click the Security tab  and click all items in the ALLOW column  for All System Packages and any user or group that allows you to add the    allow    checkmark   Click the Windows icon  Type cmd  Right click the top result and select Run as Administrator  A command window results  Type npm cache clean  If there is an error  close log files or anything open and rerun  Type npm install -g  angular cli  Or whatever npm install command you are using  Check the installation by typing ng    version  Or whatever you need to verify your install    Good luck  Note  If you are still having problems  check the Path in Environmental Variables   To access   Control Panel   System and Security   System   Advanced system settings   Environment variables   My path variable included the following  C  Users Michele AppData Roaming npm

I was already running the Node Command Window as Administrator  As mentioned by many above  the following command with --f  force  solved my issue            npm cache clean -f      After the Cache Clean  the install was flawless  See the screenshot for reference

It turns out that you don   t have to run the command again as Administrator  and doing so won   t fix the problem    Try    npm cache clean first    If that doesn   t fix things  take a look in  APPDATA  npm-cache  or if you   re using PowerShell   env APPDATA npm-cache      After cleaning the cache  you may still be left with remnants   Manually remove everything in that directory  and try again   This has always fixed things for me    As  Crazzymatt was mentioning  as of the npm 5 version and up  we need to use npm cache verify instead of npm cache clean  Or else you will get an error as preceding       npm ERR  As of npm 5  the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid  If you want to make sure everything is consistent  use  npm cache verify  instead     Source  MSDN Blog post

Like the other answers  clean npm cache and make sure the cache folder is empty  then run npm install several times  Each time the error message comes for different packages  and the final time  after X attempts  it succeeds    Run npm clean cache --force cd  APPDATA  npm-cache  or cd  env APPDATA npm-cache for PowerShell  del   to delete everything in the folder Go back into the project folder and run npm install several times until it succeeds  Notice that the error messages come for different packages every time

As my last resort with this error I created a fresh windows 10 virtual machine and installed the latest nodejs  v6   But there was a host of other  ERRs   to work through    I had to run npm cache clean --force which ironically will give you a message that reads  I sure hope you know what you are doing   That seems to have worked   It doesn t solve the issue on my main Dev machine  I m canning nodejs as I found over the last few years that you spend more time on fixing it rather than on actual development  I had fewer issues with node on linux ubuntu 14 04 if that s any help
