无法从 pyproj 导入名称转换器 注意：

问题描述

我正在尝试使用以下代码从 pyproj 中使用 Transformer。但是，我收到了一个错误。可能是什么问题？

ImportError                               Traceback (most recent call last)

解决方法

此问题已在github上解决并关闭。当我创建 mix.js('resources/js/app.js','public/js') .sass('resources/sass/app.scss','public/css'),.css( ['public/css/sidenav.css','public/css/general.css','resources/asset/jqueryui/jquery-ui.min.css','resources/asset/jqueryui/jquery-ui.structure.min.css','public/css/stt.css','public/css/ilightbox.css','public/css/flex.css','resources/asset/fontawesome/css/all.css','public/css/smartforms/smart-forms.css','public/css/smartforms/smart-themes/blue.css','public/css/hover-min.css','public/css/klik.css','public/css/spectrum.css','public/css/infobox.css',],'resources/css/app.css',.postCss('resources/css/app.css','public/css',[ require('tailwindcss')], 时，我使用了 0 info it worked if it ends with ok 1 verbose cli [ 1 verbose cli 'C:\\Program Files\\nodejs\\node.exe',1 verbose cli 'C:\\Users\\Jim\\AppData\\Roaming\\npm\\node_module\\npm\\bin\\npm-cli.js',1 verbose cli 'run',1 verbose cli 'dev' 1 verbose cli ] 2 info using npm@6.14.10 3 info using node@v14.15.3 4 verbose run-script [ 'predev','dev','postdev' ] 5 info lifecycle @~predev: @ 6 info lifecycle @~dev: @ 7 verbose lifecycle @~dev: unsafe-perm in lifecycle true 8 verbose lifecycle @~dev: PATH: C:\Users\Jim\AppData\Roaming\npm\node_modules\npm\node_modules\npm-lifecycle\node-gyp-bin;C:\Laravel\jsp\node_modules\.bin;C:\Python39\Scripts\;C:\Python39\;C:\Python27\;C:\Python27\Scripts;C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\System32\OpenSSH\;c:\php;c:\bat;C:\Program Files\Calibre2\;C:\ProgramData\ComposerSetup\bin;C:\Program Files\PuTTY\;C:\ProgramData\chocolatey\bin;C:\Program Files\nodejs\;C:\Program Files\Git\cmd;C:\Program Files\dotnet\;C:\Program Files\MySQL\MySQL Shell 8.0\bin\;C:\Users\Jim\AppData\Local\Microsoft\WindowsApps;C:\Users\Jim\AppData\Local\atom\bin;C:\Users\Jim\AppData\Roaming\Composer\vendor\bin;C:\Program Files\nodejs;C:\Program Files\Git\bin;C:\Users\Jim\AppData\Roaming\npm;C:\Users\Jim\.dotnet\tools 9 verbose lifecycle @~dev: CWD: C:\Laravel\jsp 10 silly lifecycle @~dev: Args: [ '/d /s /c','npm run development' ] 11 silly lifecycle @~dev: Returned: code: 1 signal: null 12 info lifecycle @~dev: Failed to exec dev script 13 verbose stack Error: @ dev: `npm run development` 13 verbose stack Exit status 1 13 verbose stack at EventEmitter.<anonymous> (C:\Users\Jim\AppData\Roaming\npm\node_modules\npm\node_modules\npm-lifecycle\index.js:332:16) 13 verbose stack at EventEmitter.emit (events.js:315:20) 13 verbose stack at ChildProcess.<anonymous> (C:\Users\Jim\AppData\Roaming\npm\node_modules\npm\node_modules\npm-lifecycle\lib\spawn.js:55:14) 13 verbose stack at ChildProcess.emit (events.js:315:20) 13 verbose stack at maybeClose (internal/child_process.js:1048:16) 13 verbose stack at Process.ChildProcess._handle.onexit (internal/child_process.js:288:5) 14 verbose pkgid @ 15 verbose cwd C:\Laravel\jsp 16 verbose Windows_NT 10.0.18363 17 verbose argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Users\\Jim\\AppData\\Roaming\\npm\\node_modules\\npm\\bin\\npm-cli.js" "run" "dev" 18 verbose node v14.15.3 19 verbose npm v6.14.10 20 error code ELIFECYCLE 21 error errno 1 22 error @ dev: `npm run development` 22 error Exit status 1 23 error Failed at the @ dev script. 23 error This is probably not a problem with npm. There is likely additional logging output above. 24 verbose exit [ 1,true ] ，因此您应该降级您的版本。它应该工作。您可以通过以下方式下载：

noiseplanet

这应该可以解决您的问题。

注意：

pyproj==2.6.1.post1 结构在 pip install pyproj==2.6.1.post1 中发生了变化，所以我猜这是您错误的根源。不幸的是，我不再从事 pyproj 的工作。我可能会更新软件包以使用较新的版本，但这需要时间。欢迎任何拉取请求:)

祝您有美好的一天，编码愉快！
