Yarn berry 错误：必须构建，因为以前从未构建过或最后一个失败

Question

我最近将我们的项目升级为yarn berry。仍然使用node_modules和nodeLinker：node-modules。

\n

运行“yarn”命令时，我看到以下错误：

\n

\xe2\x9e\xa4 YN0000: \xe2\x94\x8c Link step\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 core-js@npm:2.6.12 must be built because it never has been before or the last one failed\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 @getgauge/cli@npm:1.4.3 must be built because it never has been before or the last one failed\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 protobufjs@npm:6.11.3 must be built because it never has been before or the last one failed\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 core-js@npm:3.18.3 must be built because it never has been before or the last one failed\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 husky@npm:3.1.0 must be built because it never has been before or the last one failed\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 node-sass@npm:7.0.1 must be built because it never has been before or the last one failed\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 taiko@npm:1.2.7 must be built because it never has been before or the last one failed\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 taiko@npm:1.3.1 must be built because it never has been before or the last one failed\n\xe2\x9e\xa4 YN0007: \xe2\x94\x82 core-js-pure@npm:3.18.3 must be built because it never has been before or the last one failed\n

我不确定为什么纱线要求构建这些包。之前我们从未在node_modules 中构建过包。我怎样才能解决这个问题？

Answer 1

在我的项目中，当遇到此错误时，在Link step上面问题引用之前，我也遇到了许多must be built because it never has been before or the last one failed错误，其中有许多警告Resolution step，例如：

\n

\xe2\x9e\xa4 YN0000: \xe2\x94\x8c Resolution step\n\xe2\x9e\xa4 YN0002: \xe2\x94\x82 vendor-frontend@workspace:. doesn't provide @babel/core (pa3ad5), requested by @babel/plugin-proposal-class-properties\n\xe2\x9e\xa4 YN0002: \xe2\x94\x82 vendor-frontend@workspace:. doesn't provide @babel/core (p4b1ed), requested by @babel/plugin-proposal-decorators\n\xe2\x9e\xa4 YN0002: \xe2\x94\x82 (... about a dozen more ...)\n\xe2\x9e\xa4 YN0000: \xe2\x94\x82 Some peer dependencies are incorrectly met; run yarn explain peer-requirements <hash> for details, where <hash> is the six-letter p-prefixed code\n\xe2\x9e\xa4 YN0000: \xe2\x94\x94 Completed in 0s 239ms\n

\n

正如 Yarn 在最后一条消息中建议的那样，我运行了：

\n

yarn explain peer-requirements pxxxxx\n

\n

在我的例子中，pxxxxx实际上是pa3ad5第一个“”警告中的代码doesn't provide。

\n

对我来说，这产生了：

\n

\xe2\x9e\xa4 YN0000: vendor-frontend@workspace:. doesn't provide @babel/core, breaking the following requirements:\n\xe2\x9e\xa4 YN0000: @babel/helper-create-class-features-plugin@npm:7.20.7 [967d5] \xe2\x86\x92 ^7.0.0   \xe2\x9c\x98\n\xe2\x9e\xa4 YN0000: @babel/plugin-proposal-class-properties@npm:7.18.6 [8c8ef]    \xe2\x86\x92 ^7.0.0-0 \xe2\x9c\x98\n\xe2\x9e\xa4 YN0000: Note: these requirements start with @babel/plugin-proposal-class-properties@npm:7.18.6 [8c8ef]\n

\n

“npm”，是吗？这促使我运行：

\n

npm install\n

\n

至此成功完成：

\n

added 23 packages, removed 32 packages, changed 18 packages, and audited 1351 packages in 15s\n

\n

但我的应用程序（在本地开发环境中运行）仍然显示编译错误。

\n

所以我尝试回到原来的命令，再次运行：

\n

yarn install\n

\n

这成功完成，并让我的本地应用程序再次启动并运行。
