当我运行“Ionic start project name”时,我总是得到这个错误消息:

错误消息

当前回答

我通过删除node_modules,然后重新安装节点稳定版本来解决这个问题。

其他回答

我也遇到过类似的问题。当我尝试通过npm test执行Mocha时,无法找到/lib/utils目录。我尝试了这里提到的解决方案,但没有成功。最终,我卸载并重新安装了Mocha包,它是我工作的npm项目中的一个依赖项,在那之后它就工作了。因此,如果有人在将npm包作为依赖项安装时遇到了这个问题,请尝试卸载并重新安装该包(如果您还没有安装过)!

只需遵循三个步骤;

强制清除npm缓存: NPM缓存清理-f 使用npm全局安装n个包: NPM install -g 从以下三个选项中任意一个安装: A. sudo n stable(获取稳定版) B. sudo n latest(获取节点的最新版本) C. sudo n X.X.X(获取节点的具体版本)

尝试删除/usr/local/lib/node_modules/npm并重新安装node。这应该有用。

在MacOS上使用Homebrew:

sudo rm -rf /usr/local/lib/node_modules/npm
brew reinstall node

./lib/node_modules/npm/bin/npm-cli.js中的require('../lib/utils/unsupported.js')导致无法找到模块'../lib/utils/unsupported.js'错误。

根据nodejs require docs,所需的模块相对于文件进行搜索,因为它以../开头。

因此,如果我们从。/lib/node_modules/npm/bin/npm-cli.js开始选择相对路径../lib/utils/unsupported.js,那么所需的模块必须位于。/lib/node_modules/npm/lib/utils/unsupported.js中。如果它不在那里,我看到两个选项:

the installation is corrupt, in which case Vincent Ducastel's answer to reinstall node might work npm is no symlink to ./lib/node_modules/npm/bin/npm-cli.js. This is what caused the error in my setup. If you call npm, it will typically find it be searching it in the directories listed in the PATH env var. It might for example be located in ./bin. However, npm in a ./bin directory should only be a symlink to the aforementioned ./lib/node_modules/npm/bin/npm-cli.js. If it is not a symlink but directly contains the code, somewhere in the installation process the symlink got replaced by the file it links to. In this case, it should be sufficient to recreate the symlink: cd ./bin; rm npm; ln -s ../lib/node_modules/npm/bin/npm-cli.js npm (update: command fixed, thx @massimo)

所有建议检查NODE_PATH或npmrc配置的答案都应该被忽略,因为相对地搜索模块时不会考虑这些。

在fedora 27上,我这样解决了这个问题:

sudo rm -f  /usr/local/lib/node_modules/npm
sudo dnf reinstall nodejs
