I have NVM 0.30.1 and used it to install node.js v5.4.0 (with NPM 3.5.4) on Fedora 22. When I run npm update -g, I receive the following warnings:

我有 NVM 0.30.1 并用它在 Fedora 22 上安装 node.js v5.4.0（带有 NPM 3.5.4）。当我运行时npm update -g，我收到以下警告：

npm WARN EBUNDLEOVERRIDE Replacing bundled npm > node-gyp with new installed version
npm WARN EBUNDLEOVERRIDE Replacing bundled npm > npm-install-checks with new installed version
npm WARN EBUNDLEOVERRIDE Replacing bundled npm > npmlog with new installed version
npm WARN EBUNDLEOVERRIDE Replacing bundled npm > read-package-json with new installed version

And after that, when I run npm I get this error:

之后，当我运行 npm 时，出现此错误：

    throw err;
    ^

Thanks for the answers. It was a bugand it has already been fixed in Node v5.4.1. Now it's working as usual.

What fixed this for me was

为我解决这个问题的是

sudo rm -rf /usr/local/lib/node_modules/

and then re-installing node (with npm).

然后重新安装节点（使用 npm）。

It looks like npm update -gcannot update npm to the newest version. I solve the problem by updating npm installation manually.

看起来npm update -g无法将 npm 更新到最新版本。我通过手动更新 npm 安装解决了这个问题。

1. Install/ reinstall node to get the bundled npm
2. run npm install -g [email protected]to update the global npm installation
3. now npm update -gshould work

1. 安装/重新安装节点以获取捆绑的 npm
2. 运行npm install -g [email protected]以更新全局 npm 安装
3. 现在npm update -g应该工作

I have faced the same issue in my Windows 10 PC. After looking into solutions, since i couldn't find the exact solution for the issue i was facing Cannot find module 'npmlog'I just uninstalled the node js and then, deleted both 'npm' and 'npm-cache' in "C:\Users\YourPCName\AppData\Roaming"

我在 Windows 10 PC 中遇到了同样的问题。在研究解决方案后，由于我找不到我面临的问题的确切解决方案 无法找到模块“npmlog”，我只是卸载了节点 js，然后在“C: \Users\YourPCName\AppData\Roaming”

Then, i downloaded the latest version of node from Node JS Website

然后，我从Node JS 网站下载了最新版本的 node

And, installed node js

并且，安装了节点js

After that i checked with the path in environment variables.

之后我检查了环境变量中的路径。

Finally run the command prompt 'run as administrator' and npm install npm -g

最后运行命令提示符“以管理员身份运行”和npm install npm -g

Checking your version will show the latest version. 'npm -v'

检查您的版本将显示最新版本。'npm -v'

I got the latest version - v3.10.9

我得到了最新版本 - v3.10.9

Try this. this should work.

尝试这个。这应该有效。

If people with linux are facing the problem, here is the solution:

如果使用 linux 的人遇到问题，这里是解决方案：

As of the date of this post, the NPM version packaged with Nodejs doesn't work. If you installed this package, run

截至本文发布之日，与 Nodejs 一起打包的 NPM 版本不起作用。如果你安装了这个包，运行

sudo rm -rf /usr/local/bin/npm
sudo apt-get install node
sudo mv /usr/bin/npm /usr/local/bin/npm

New version should be 3.10.8 and the old error gone

新版本应该是 3.10.8 并且旧的错误消失了

init-package-json, node-gyp, npm-install-checks, npmlog, read-package-json didn't installed correctly. Not sure why though.

init-package-json、node-gyp、npm-install-checks、npmlog、read-package-json 未正确安装。不知道为什么。

Didn't find the root cause for the issue but I used the hacky way to install the packages above for now:

没有找到问题的根本原因，但我现在使用 hacky 方式来安装上面的软件包：

• Roll back to the previous node version which npm didn't be updated. For example, nvm use iojs
• cdto where npm installed, for example, cd /home/peflorencio/.nvm/versions/node/v5.4.0/lib/node_modules/npmand reinstall those packages like rm -rf node_modules/init-package-json && npm install init-package-jsonetc.

• 回滚到之前没有更新 npm 的节点版本。例如，nvm use iojs
• cd例如，安装到 npm 的位置，cd /home/peflorencio/.nvm/versions/node/v5.4.0/lib/node_modules/npm然后重新安装这些软件包等rm -rf node_modules/init-package-json && npm install init-package-json。

Some of the answers already answered the question, but I will still like to throw in my own idea. I encountered same issue after I was told to run npm update -g npmafter running that piece of code, the error started. I solved mine by using Node Version Manager(nvm):

一些答案已经回答了这个问题，但我仍然想提出我自己的想法。在我被告知npm update -g npm在运行那段代码后运行后，我遇到了同样的问题，错误开始了。我使用 Node Version Manager( nvm)解决了我的问题：

nvm install 8

Note:not actually 8, but to a version of your choice e.g(6,5). Writing the version number will automatically install the stable of the version specified. After the installation you should get a CLI message:

注意：实际上不是 8，而是您选择的版本，例如（6,5）。写入版本号将自动安装指定版本的稳定版。安装后，您应该会收到一条 CLI 消息：

Now using node v8.11.4 (npm v5.6.0)

If you're using a Mac, perform the following steps, to remedy (assuming you have Homebrew installed already):

如果您使用的是 Mac，请执行以下步骤以进行补救（假设您已经安装了 Homebrew）：

sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*

(to overcome bash: /usr/local/bin/npm: No such file or directoryerror):

（克服bash: /usr/local/bin/npm: No such file or directory错误）：

hash -r 

Then go ahead with updating brew (to keep its kegs up to date) and the reinstallation process, linking is optional.

然后继续更新 brew（以使其小桶保持最新）和重新安装过程，链接是可选的。

brew update

brew reinstall node

brew link --overwrite node

At any point inbetween you can use npm -vor node -vto test whether or not you are making progress. If you have nodereturning a version, but not npmthen you will need to add your path to your environment with:

在两者之间的任何时候，您都可以使用npm -v或node -v来测试您是否正在取得进展。如果您node返回了一个版本，但没有返回，npm那么您需要将您的路径添加到您的环境中：

export PATH="/usr/local/bin:$PATH"
