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

./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。
