无法更新 npm 包：ERR！ 代码 EEXIST

Question

I'm trying to to upgrade npm packages via

npm update -g

But, I get this error:

npm ERR! path C:\Program Files\nodejs\npm
npm ERR! code EEXIST
npm ERR! Refusing to delete C:\Program Files\nodejs\npm: is outside C:\Program Files\nodejs\node_modules\npm and not a link
npm ERR! File exists: C:\Program Files\nodejs\npm
npm ERR! Move it away, and try again.

I've googled but none of the solutions work. One sadi to remove the npm.cmd and npm files from here:

C:\Program Files\nodejs\

I tried that, but it fails as npm is now missing.

That folder, C:\\Program Files\\nodejs\\, is actually a shortcut pointing to

C:\Users\lthurman\AppData\Roaming\nvm\v8.11.1

I'm using nvm to manage my node installations, any ideas on how to fix this?

Thanks

Answer 1

在删除文件夹C:\\Users\\xxx\\AppData\\Roaming\\npm ， C:\\Users\\xxx\\AppData\\Roaming\\npm-cache后尝试执行以下命令。

npm install -g npm@latest

Answer 2

To resolve this issue I took the following steps

Where [userName] is your Windows user name -- [nodeVer] is your current version of Node, or the one that is giving you issues using NVM

Delete these four files:

C:\Users\[userName]\AppData\Roaming\nvm\[nodeVer]\npm
C:\Users\[userName]\AppData\Roaming\nvm\[nodeVer]\npm.cmd
C:\Users\[userName]\AppData\Roaming\nvm\[nodeVer]\npx
C:\Users\[userName]\AppData\Roaming\nvm\[nodeVer]\npx.cmd

Then in C:\\Users\\[userName]\\AppData\\Roaming\\nvm\\[nodeVer]\\node_modules\\ , rename the npm directory to npm_old

Open up your console of choice -- run as admin if necessary -- and navigate into the \\npm_old\\bin directory then install NPM at latest (or replace latest w/a version of your choosing) using the command below:

node npm-cli.js i -g npm@latest

Clean-up by deleting the npm_old directory from earlier. Now all should be good to go...I hope!

Answer 3

It will fixed it by forcing the install with --force

npm install -g npm@latest --force

Uninstall old version first

npm uninstall -g your-package-name

install the latest

npm install -g your-package-name@latest
