使用cnpm 安装jest会出现如下警告：
peerDependencies WARNING jest@26.6.3 › jest-cli@26.6.3 › jest-config@^26.6.3 requires a peer of ts-node@>=9.0.0 but none was installed
peerDependencies WARNING jest@26.6.3 › jest-cli@26.6.3 › jest-config@26.6.3 › jest-environment-jsdom@26.6.2 › jsdom@^16.4.0 requires a peer of canvas@^2.5.0 but none was installed
peerDependencies WARNING jest@26.6.3 › jest-cli@26.6.3 › jest-config@26.6.3 › jest-environment-jsdom@26.6.2 › jsdom@16.5.3 › ws@^7.4.4 requires a peer of bufferutil@^4.0.1 but none was installed

然后后面使用npm去安装其他依赖时，就会报canvas找不到的错，请问老师这个是什么原因，是不是jest的版本问题？
