为什么 npm 我无法完成安装？ 为什么它告诉节点和 npm 是无效命令？

Question

试图运行一个 React 项目。 我已经安装了最新的节点，并根据自述文件尝试了旧版本。 我已经卸载了 Node，从 APPDATA/ROAMING 和 ProgramFiles 中清除了它的所有痕迹，然后重新安装。 同事机器上有各种版本的Node和npm，可以在本地运行项目。 我检查了我的环境变量并确保正确设置了 PATH 属性。 我已经从 JSON 文件中删除了这个特定的 package 并重试并看到类似的问题。 节点和 npm 安装清晰。 有人遇到过这种情况或有尝试的建议吗？ 我已经为此工作了好几天。 谢谢。

Answer 1

我会尝试再次重新安装 Node！

Answer 2

我曾经在它似乎安装的地方安装过它，但在执行命令时却没有。 就像你一样。 即使重新安装npm和node，结果还是一样。 我重新启动了计算机，这为我解决了问题。 相当蹩脚的解决方案，我花了一段时间才发现。

希望这对你也有帮助。
