错误: 无法找到模块’. ./lib/cli’

我对 javascript 开发完全是新手，当我在主干 _ 蓝图手册中工作时，我遇到了以下错误。我得到的错误是:

> simple-blog@0.1.0 start /Users/noahc/Projects/backbone_blueprints/blog

我认为这可能是一个路径问题，所以我将 export NODE_PATH=/opt/lib/node_modules添加到我的。然后找到了它的源代码，这似乎没有任何影响。

有什么想法，无论如何，我可以故障排除这个或试图更好地理解实际发生了什么？

I found the fix. I had to install nodemon globally doing this: npm install nodemon -g

My solution was to just delete the directory /node_modules/ and to make a fresh install afterwards with npm install.

Had the same problem.

I use protractor --elementExplorer and it works for me

You can try doing the following

npm uninstall nodemon
npm install nodemon

Nodedemon is looking for its ../lib/cli folder in its own directory and not finding it. You probably have a messed up install. This can happen sometimes when you use finder to copy a project from one folder to another.

If you blow away your node_modules directory and reinstall from scratch, you should restore the folder.

cd your_project_folder
rm -rf node_modules
npm install

Edit:

You might also use yarn.

cd your_project_folder
rm -rf node_modules
yarn

Protractor have changed the location.The lib/built protractor files now reside in the built directory of the package. You should just be able to direct your IDE to built/cli.js This worked for me.

Check their Github Issue link :

For me npm was broken, probably because I ran it with sudo at some point.

I needed to fix brew, upgrade/update

brew uninstall node
sudo chown -R $(whoami) /usr/local/*
brew cleanup
brew install node

So npm creates a symbolic link between modules that have an executable declared in the package.json file and the node_modules/.bin directory.

Read from npm to understand.

Dr. Axel Rauschmayer explains more here.

When ever a project directory and its node_modules folder is copied using macos finder, windows file explorer or command line, this symlink is destroyed. Thus calls to the symbolically linked file on the node_modules/.bin directory cannot hit the supposed package.

In your case it was nodemon . To manually fixed this run

ln -s ./node_modules/nodemon/bin/nodemon.js ./node_modules/.bin/nodemon

for any other package, check the "bin": { } key in it's package.json and see the the symlinked executable, then modify the link command above and run according.

brew uninstall node
brew upgrade
brew install node
brew link --overwrite node
npm -v

Worked for me.

I had this error, leaving this here in case it helps anyone.

I installed yarn and apparently messed up my node install, tried to fix it by uninstalling stuff, made a total mess. Brew wouldn't install node successfully (old OS maybe out of LTS, installing from source code wouldn't make npm work).

Even

npm -v

would give the error (so nothing to do with node_modules). Finally fixed it by installing node using a package manager from here.

brew link --overwrite node

Is all that is needed. No need to uninstall.

In macOS BigSur i had to clean up the node modules folder first:

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

Note: Reason i needed sudo is some of the folders need special permission to remove them.

After removing node_modules I had reinstalled npm package by:

brew postinstall node

Finally i was able to see npm back into my mac:

npm -v
7.21.1

I was getting same error after installing nodejs using homebrew to fix it I have downloaded and installed nodejs from it's official website. It's working fine now.
