错误:在使用Ionic时找不到模块“../lib/utils/unsupported.js”

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

在Mac OS X(10.12.6)上，我通过以下方法解决了这个问题:

brew uninstall --force node
brew install node

然后我得到一个错误，抱怨节点postinstall失败，并重新运行brew postinstall节点

然后我得到一个错误:

permission denied @ rb_sysopen /usr/local/lib/node_modules/npm/bin/npx

我通过以下方法解决了这个错误:

sudo chown -R $(whoami):admin /usr/local/lib/node_modules

现在我不会再得到这个错误了。

我通过运行下面的命令解决了这个问题

NVM安装节点——reinstall-packages-from=node

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

如前所述。

 sudo rm -rf /usr/local/lib/node_modules/npm
 brew uninstall --force node                
 brew install 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。
